|
|
|
|
|
|
|
I. IMPORTANT CHANGES
|
|
|
|
|
|
|
|
|
|
- Some fields in the `CID_FaceDictRec`, `CID_FaceInfoRec`, and
|
|
|
|
|
`FT_Data` structures have been changed from signed to unsigned
|
|
|
|
|
type, which better reflects the actual usage. It is also an
|
|
|
|
|
additional means to protect against malformed input.

II. MISCELLANEOUS
|
|
|
|
|
|
|
|
|
|
- Cmake support has been further improved. To do that various
|
|
|
|
|
backward-incompatible changes were necessary; please see file
|
|
|
|
|
`CMakeLists.txt` for more details.
|
|
|
|
|
|
|
|
|
|
- Since version 2.11.0, a C99 compiler is necessary to compile
|
|
|
|
|
FreeType.
|
|
|
|
|
|
|
|
|
|
- The experimental 'COLR' v1 API has been updated to the latest
|
|
|
|
|
OpenType standard 1.9.
|
|
|
|
|
|
|
|
|
|
- The `apinames` tool got a new option `-wV` to output an OpenVMS
|
|
|
|
|
Linker Option File.
|
|
|
|
|
|
|
|
|
|
- VMS support was updated.
|
|
|
|
|
|
|
|
|
|
- MS Visual Studio support was added to build the demo programs.

I. IMPORTANT CHANGES
|
|
|
|
|
|
2021-06-08 17:44:34 +02:00
|
|
|
- A new rendering module has been added to create 8-bit Signed
|
2020-12-24 07:44:16 +01:00
|
|
|
Distance Field (SDF) bitmaps for both outline and bitmap glyphs.
|
|
|
|
|
The new rendering mode is called `FT_RENDER_MODE_SDF`, the pixel
|
2021-06-08 17:44:34 +02:00
|
|
|
mode is `FT_PIXEL_MODE_GRAY8`, and the corresponding raster flag
|
2020-12-24 07:44:16 +01:00
|
|
|
is `FT_RASTER_FLAG_SDF`.

|
|
|
|
2021-01-15 14:49:32 +01:00
|
|
|
- A new, experimental API is now available for surfacing properties
|
|
|
|
|
of 'COLR' v1 color fonts (as the name says, this is an extension
|
|
|
|
|
to the 'COLR' table for outline color fonts using the SFNT
|
|
|
|
|
container format). 'COLR' v1 fonts are a recently proposed
|
|
|
|
|
addition to OFF and OpenType; specification work currently happens
|
|
|
|
|
in
|
|
|
|
|
|
|
|
|
|
https://github.com/googlefonts/colr-gradients-spec/
|
|
|
|
|
|
|
|
|
|
'COLR' v1 is expected to be merged to OpenType; the ISO
|
|
|
|
|
standardisation process for adding 'COLR' v1 as an amendment to
|
|
|
|
|
OFF is underway.
|
|
|
|
|
|
|
|
|
|
Functions similar to the already existing 'COLR' API have been
|
|
|
|
|
added to access the corresponding data.
|
|
|
|
|
|
|
|
|
|
FT_Get_Color_Glyph_Paint
|
|
|
|
|
Retrieve the root paint for a given glyph ID.
|
|
|
|
|
|
|
|
|
|
FT_Get_Paint_Layers
|
|
|
|
|
Access the layers of a `PaintColrLayers` table.
|
|
|
|
|
|
|
|
|
|
FT_Get_Colorline_Stops
|
|
|
|
|
Retrieve the 'color stops' on a color line. As an input, a
|
|
|
|
|
color stop iterator gets used, which in turn is retrieved from
|
|
|
|
|
a paint.
|
|
|
|
|
|
|
|
|
|
FT_Get_Paint
|
|
|
|
|
Dereference an `FT_OpaquePaint` object and retrieve the
|
|
|
|
|
corresponding `FT_COLR_Paint` object, which contains details
|
|
|
|
|
on how to draw the respective 'COLR' v1 `Paint` table.

II. MISCELLANEOUS
|
|
|
|
|
|
2021-01-16 15:45:13 +01:00
|
|
|
- FreeType has moved its infrastructure to
|
|
|
|
|
|
|
|
|
|
https://gitlab.freedesktop.org/freetype
|
|
|
|
|
|
|
|
|
|
A side effect is that the git repositories are now called
|
|
|
|
|
`freetype.git` and `freetype-demos.git`, which by default expand
|
|
|
|
|
to the directories `freetype` and `freetype-demos`, respectively.
|
|
|
|
|
The documentation has been updated accordingly.
|
|
|
|
|
|
|
|
|
|
FreeType's Savannah repositories will stay; they are now mirrors
|
|
|
|
|
of the 'freedesktop.org' repositories.
|
|
|
|
|
|
2021-02-13 08:52:58 +01:00
|
|
|
- A new function `FT_Get_Transform` returns the values set by
|
|
|
|
|
`FT_Set_Transform`.
|
|
|
|
|
|
|
|
|
|
- A new configuration macro `FT_DEBUG_LOGGING` is available. It
|
|
|
|
|
provides extended debugging capabilities for FreeType, for example
|
|
|
|
|
showing a time stamp or displaying the component a tracing message
|
|
|
|
|
comes from. See file `docs/DEBUG` for more information.

|
|
|
|
|
|
2021-07-18 07:53:57 +02:00
|
|
|
- The legacy Type 1 and CFF engines are further demoted due to lack
|
|
|
|
|
of CFF2 charstring support. You now need to use `FT_Property_Set`
|
|
|
|
|
to enable them besides the `T1_CONFIG_OPTION_OLD_ENGINE` and
|
|
|
|
|
`CFF_CONFIG_OPTION_OLD_ENGINE` options, respectively.
|
|
|
|
|
|
2021-07-12 22:03:25 +02:00
|
|
|
- The experimental 'warp' mode (AF_CONFIG_OPTION_USE_WARPER) for the
|
|
|
|
|
auto-hinter has been removed.
|
|
|
|
|
|
2021-07-16 08:20:44 +02:00
|
|
|
- The smooth rasterizer performance has been improved by >10%. Note
|
|
|
|
|
that due to necessary code changes there might be very subtle
|
|
|
|
|
differences in rendering. They are not visible by the eye,
|
|
|
|
|
however.

|
|
|
|
2021-06-08 18:23:16 +02:00
|
|
|
- PCF bitmap fonts compressed with LZW (these are usually files with
|
|
|
|
|
the extension `.pcf.Z`) are now handled correctly.
|
|
|
|
|
|
2021-07-18 07:53:57 +02:00
|
|
|
- Improved Meson build files, including support to build the
|
|
|
|
|
FreeType demo programs.
|
2021-06-08 17:44:34 +02:00
|
|
|
|
2021-06-30 10:23:42 +02:00
|
|
|
- A new demo program `ftsdf` is available to display Signed Distance
|
|
|
|
|
Fields of glyphs.
|
2021-02-13 08:52:58 +01:00
|
|
|
|
2021-06-30 10:23:42 +02:00
|
|
|
- The `ftlint` demo program has been extended to do more testing of
|
|
|
|
|
its input. In particular, it can display horizontal and vertical
|
|
|
|
|
acutances for quality assessment, together with computing MD5
|
|
|
|
|
checksums of rendered glyphs.
|
|
|
|
|
|
|
|
|
|
[The acutance measures how sharply the pixel coverage changes at
|
|
|
|
|
glyph edges. For monochrome bitmaps, it is always 2.0 in either
|
|
|
|
|
X or Y direction. For anti-aliased bitmaps, it depends on the
|
|
|
|
|
hinting and the shape of a glyph and might approach or even reach
|
|
|
|
|
value 2.0 for glyphs like 'I', 'L', '+', '-', or '=', while it
|
|
|
|
|
might be lower for glyphs like 'O', 'S', or 'W'.]
|
|
|
|
|
|
|
|
|
|
- The `ttdebug` demo program didn't show changed point coordinates
|
|
|
|
|
(bug introduced in version 2.10.3).
|
|
|
|
|
|
|
|
|
|
- It is now possible to adjust the axis increment for variable fonts
|
|
|
|
|
in the `ftmulti` demo program.
|
|
|
|
|
|
|
|
|
|
- It is now possible to change the hinting engine in the `ftstring`
|
|
|
|
|
demo program.
|
|
|
|
|
|
|
|
|
|
- The graphical demo programs work better now in native color depth
|
|
|
|
|
on win32 and x11.

I. IMPORTANT BUG FIXES
|
|
|
|
|
|
|
|
|
|
- A heap buffer overflow has been found in the handling of embedded
|
|
|
|
|
PNG bitmaps, introduced in FreeType version 2.6.
|
|
|
|
|
|
|

|
|
|
|
|
|
|
|
|
|
If you use option FT_CONFIG_OPTION_USE_PNG you should upgrade
|
|
|
|
|
immediately.

CHANGES BETWEEN 2.10.2 and 2.10.3 (2020-Oct-10)
|
2020-10-10 12:48:18 +02:00
|
|
|
|
|
|
|
|
I. IMPORTANT CHANGES
|
|
|
|
|
|
|
|
|
|
- New flag `FT_OUTLINE_OVERLAP'. If set, make the smooth rasterizer
|
|
|
|
|
do 4x4 oversampling to mitigate artifacts in pixels partially
|
|
|
|
|
covered by overlapping contours. Note that this at least
|
|
|
|
|
quadruples the rendering time.
|
|
|
|
|
|
|
|
|
|
If a glyph in a TrueType font has the `OVERLAP_SIMPLE' or
|
|
|
|
|
`OVERLAP_COMPOUND' bit set, FreeType automatically selects this
|
|
|
|
|
rendering mode.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
II. MISCELLANEOUS
|
|
|
|
|
|
|
|
|
|
- Using the arcane method of including FreeType header files with
|
|
|
|
|
macros like `FT_FREETYPE_H' is no longer mandatory (but retained
|
|
|
|
|
as an optional feature for backward compatibility).
|
|
|
|
|
|
|
|
|
|
- Support for building the library with Meson. Building the demo
|
|
|
|
|
programs with Meson will follow in a forthcoming release.
|
|
|
|
|
|
|
|
|
|
- Minor improvements to the B/W rasterizer.
|
|
|
|
|
|
|
|
|
|
- Auto-hinter support for Medefaidrin script.
|
|
|
|
|
|
|
|
|
|
- Fix various memory leaks (mainly for CFF) and other issues that
|
|
|
|
|
might cause crashes in rare circumstances.
|
|
|
|
|
|
|
|
|
|
- Jam support has been removed.
|
|
|
|
|
|
|
|
|
|
- In `ftview', custom LCD filter values are now normalized and
|
|
|
|
|
balanced. Unorthodox filters are still available through the `-L'
|
|
|
|
|
command line option.
|
|
|
|
|
|
|
|
|
|
- The GUI demo programs can now be resized.
|
|
|
|
|
|
|
|
|
|
- Demo programs that accept command line option `-k' can now handle
|
|
|
|
|
function keys, too. The corresponding character codes start with
|
|
|
|
|
0xF1. As an example, the POSIX shell syntax (accepted by bash,
|
|
|
|
|
ksh, and zsh)
|
|
|
|
|
|
|
|
|
|
-k $'\xF3q'
|
|
|
|
|
|
|
|
|
|
emulates the pressing of function key `F3' followed by key `q'.

|
|
|
|
|
|
2019-08-27 14:07:05 +02:00
|
|
|
- Support of WOFF2 fonts. This code contribution was Nikhil
|
|
|
|
|
Ramakrishnan's GSoC 2019 project.

|
|
|
|
|
MM fonts.
|
|
|
|
|
|
2020-05-05 20:14:14 +02:00
|
|
|
- Type 1 fonts with non-integer metrics are now supported by the new
|
|
|
|
|
(CFF) engine introduced in FreeType 2.9.
|
|
|
|
|
|
2020-03-21 15:47:17 +01:00
|
|
|
- Drop support for Python 2 in Freetype's API reference generator
|
|
|
|
|
`docwriter' (Python >= 3.5 is required for targets `make refdoc'
|
|
|
|
|
and `make refdoc-venv').
|
|
|
|
|
|
2020-10-10 12:48:18 +02:00
|
|
|
- Auto-hinter support for Hanifi Rohingya.
|
2020-05-05 20:14:14 +02:00
|
|
|
|
|
|
|
|
- Document the `FT2_KEEP_ALIVE' debugging environment variable.
|
|
|
|
|
|
|
|
|
|
- The Visual C++ (and Visual C) project files for Windows builds no
|
|
|
|
|
longer generate libraries that contain the FreeType version in its
|
|
|
|
|
filenames. Instead, a resource file gets used to make the
|
|
|
|
|
libraries contain the corresponding information.
|
|
|
|
|
|
2020-04-30 08:37:16 +02:00
|
|
|
- The next release will remove Jam build support.

I. IMPORTANT BUG FIXES
|
|
|
|
|
|
2019-05-16 12:52:57 +02:00
|
|
|
- The bytecode hinting of OpenType variation fonts was flawed, since
|
|
|
|
|
the data in the `CVAR' table wasn't correctly applied.
|
|
|
|
|
|
2019-04-06 06:51:08 +02:00
|
|
|
|
|
|

|
II. MISCELLANEOUS
|
|
|
|
|
|
|
|
|
|
- Auto-hinter support for Mongolian.
|
|
|
|
|
|
|
|
|
|
- For distribution, `.tar.bz2' packages are replaced with `.tar.xz'
|
|
|
|
|
bundles.
|
|
|
|
|
|
2019-04-17 07:49:17 +02:00
|
|
|
- The handling of the default character in PCF fonts as introduced
|
2019-04-19 07:07:01 +02:00
|
|
|
in version 2.10.0 was partially broken, causing premature abortion
|
2019-04-17 07:49:17 +02:00
|
|
|
of charmap iteration for many fonts.
|
|
|
|
|
|
2019-04-22 07:41:35 +02:00
|
|
|
- If `FT_Set_Named_Instance' was called with the same arguments
|
|
|
|
|
twice in a row, the function returned an incorrect error code the
|
|
|
|
|
second time.
|
|
|
|
|
|
2019-06-10 15:37:33 +02:00
|
|
|
- Direct rendering using FT_RASTER_FLAG_DIRECT crashed (bug
|
|
|
|
|
introduced in version 2.10.0).
|
|
|
|
|
|
2019-05-16 12:52:57 +02:00
|
|
|
- Increased precision while computing OpenType font variation
|
|
|
|
|
instances.
|
|
|
|
|
|
2019-06-10 15:37:33 +02:00
|
|
|
- The flattening algorithm of cubic Bezier curves was slightly
|
|
|
|
|
changed to make it faster. This can cause very subtle rendering
|
|
|
|
|
changes, which aren't noticeable by the eye, however.
|
|
|
|

2019-06-19 16:45:39 +02:00
|
|
|
- The auto-hinter now disables hinting if there are blue zones
|
|
|
|
|
defined for a `style' (i.e., a certain combination of a script and
|
|
|
|
|
its related typographic features) but the font doesn't contain any
|
|
|
|
|
characters needed to set up at least one blue zone.
|
|
|
|
|
|
2019-06-10 15:37:33 +02:00
|
|
|
- The `ftmulti' demo program now supports multiple hidden axes with
|
|
|
|
|
the same name tag.
|
|
|
|
|
|
|
|
|
|
- `ftview', `ftstring', and `ftgrid' got a `-k' command line option
|
|
|
|
|
to emulate a sequence of keystrokes at start-up.
|
|
|
|
|
|
|
|
|
|
- `ftview', `ftstring', and `ftgrid' now support screen dumping to a
|
|
|
|
|
PNG file.
|
|
|
|
|
|
|
|
|
|
- The bytecode debugger, `ttdebug', now supports variation TrueType
|
|
|
|
|
fonts; a variation font instance can be selected with the new `-d'
|
|
|
|
|
command line option.

I. IMPORTANT CHANGES
|
2018-08-19 07:27:21 +02:00
|
|
|
|
2018-09-01 11:01:52 +02:00
|
|
|
- A bunch of new functions has been added to access and process
|
2019-02-23 11:21:48 +01:00
|
|
|
COLR/CPAL data of OpenType fonts with color-layered glyphs.
|
2018-08-19 07:27:21 +02:00
|
|
|
|
|
|
|
|
FT_Palette_Data_Get
|
2019-02-23 11:21:48 +01:00
|
|
|
Retrieve color palette data.
|
2018-08-19 07:27:21 +02:00
|
|
|
FT_Palette_Select
|
2019-02-23 11:21:48 +01:00
|
|
|
Select and activate a color palette for color-layered
|
|
|
|
|
glyphs.
|
2018-08-19 07:27:21 +02:00
|
|
|
FT_Palette_Set_Foreground_Color
|
2019-02-23 11:21:48 +01:00
|
|
|
Set text foreground color for palette index 0xFFFF.
|
|
|
|
|
|
2018-08-19 07:27:21 +02:00
|
|
|
FT_Get_Color_Glyph_Layer
|
2019-02-23 11:21:48 +01:00
|
|
|
Get color layers for a given glyph (using an interator
|
|
|
|
|
object).
|
|
|
|
|
|
2018-08-19 07:27:21 +02:00
|
|
|
FT_Bitmap_Blend
|
2019-02-23 11:21:48 +01:00
|
|
|
Blend one bitmap onto another with a given color.
|
|
|
|
|
|
|
|
|
|
- An experimental feature is the new behaviour of the
|
|
|
|
|
`FT_LOAD_COLOR' load flag for color-layered glyphs: Internally
|
|
|
|
|
it sets a flag so that if `FT_Render_Glyph' is called with
|
|
|
|
|
`FT_RENDER_MODE_NORMAL' (or `FT_Load_Glyph' with
|
|
|
|
|
`FT_LOAD_RENDER'), a default blending of the color glyph layers
|
|
|
|
|
will happen automatically for convenience.
|

|
|
|
|
2019-03-08 00:13:08 +01:00

|
|
|
|
|
overhauled and modernized the API reference.

II. MISCELLANEOUS
|
2018-08-19 07:27:21 +02:00
|
|
|
|
2019-02-06 07:38:25 +01:00
|
|
|
- The logic for computing the global ascender, descender, and
|
|
|
|
|
height of OpenType fonts has been slightly adjusted for
|
|
|
|
|
consistency.
|
|
|
|
|
|
|
|
|
|
. If the `useTypoMetrics' flag (i.e., bit 7 in the `fsSelection'
|
|
|
|
|
field) in the `OS/2' table is set, use the `sTypo' fields in
|
|
|
|
|
`OS/2' unconditionally.
|
|
|
|
|
. Otherwise use the metrics data from the `hhea' table (if not
|
|
|
|
|
zero).
|
2019-03-08 00:13:08 +01:00
|
|
|
. Otherwise use the `sTypo' fields from the `OS/2' table (if not
|
|
|
|
|
zero).
|
2019-02-06 07:38:25 +01:00
|
|
|
. Otherwise use the `usWin' data from the `OS/2' table as a last
|
|
|
|
|
resort.
|
|
|
|
|
|
|
|
|
|
Variable fonts will apply the `MVAR' deltas to whichever metrics
|
|
|
|
|
were picked.
|
|
|
|
|
|
2018-09-01 11:01:52 +02:00
|
|
|
- `TT_Set_MM_Blend' could fail if call repeatedly with the same
|
2018-08-19 07:27:21 +02:00
|
|
|
arguments.
|
|
|
|
|
|
2018-09-01 11:01:52 +02:00
|
|
|
- The precision of handling deltas in Variation Fonts has been
|
|
|
|
|
increased. The problem did only show up with multidimensional
|
2018-08-19 07:27:21 +02:00
|
|
|
designspaces.
|
|
|
|
|
|
2018-09-01 11:01:52 +02:00
|
|
|
- New function `FT_Library_SetLcdGeometry' to set up the geometry
|
2018-08-19 07:27:21 +02:00
|
|
|
of LCD subpixels.
|
|
|
|
|
|
|
|
|
|
- FreeType now uses the `defaultChar' property of PCF fonts to set
|
2018-09-01 11:01:52 +02:00
|
|
|
the glyph for the undefined character at glyph index 0 (as
|
2018-08-19 07:27:21 +02:00
|
|
|
FreeType already does for all other supported font formats). As
|
2018-09-01 11:01:52 +02:00
|
|
|
a consequence, the order of glyphs of a PCF font if accessed
|
|
|
|
|
with FreeType can be different now compared to previous
|
|
|
|
|
versions.
|
2018-08-19 07:27:21 +02:00
|
|
|
|
|
|
|
|
This change doesn't affect PCF font access with cmaps.
|
|
|
|
|
|
2018-09-01 11:01:52 +02:00
|
|
|
- `FT_Select_Charmap' has been changed to allow parameter value
|
2018-08-19 07:27:21 +02:00
|
|
|
`FT_ENCODING_NONE', which is valid for BDF, PCF, and Windows FNT
|
2018-09-01 11:01:52 +02:00
|
|
|
formats to access built-in cmaps that don't have a predefined
|
2018-08-19 07:27:21 +02:00
|
|
|
`FT_Encoding' value.
|
|
|
|
|
|
2018-09-01 11:01:52 +02:00
|
|
|
- A previously reserved field in the `FT_GlyphSlotRec' structure
|
2018-08-19 07:27:21 +02:00
|
|
|
now holds the glyph index.
|
|
|
|
|
|
2018-09-01 11:01:52 +02:00
|
|
|
- On Win32 platforms, the use of `_DLL' to build the library has
|
2018-08-19 07:27:21 +02:00
|
|
|
been replaced with `DLL_EXPORT' and `DLL_IMPORT'.
|
|
|
|
|
|
2018-09-01 11:01:52 +02:00
|
|
|
- The usual round of fuzzer bug fixes to better reject malformed
|
2018-08-19 07:27:21 +02:00
|
|
|
fonts.
|
|
|
|
|
|
2018-09-01 11:01:52 +02:00
|
|
|
- `FT_Outline_New_Internal' and `FT_Outline_Done_Internal' have
|
|
|
|
|
been removed. These two functions were public by oversight only
|
2018-12-10 12:11:54 +01:00
|
|
|
and were never documented.
|
|
|
|
|
|
|
|
|
|
- A new function `FT_Error_String' returns descriptions of error
|
|
|
|
|
codes if configuration macro FT_CONFIG_OPTION_ERROR_STRINGS is
|
|
|
|
|
defined.
|
|
|
|
|
|
|
|
|
|
- `FT_Set_MM_WeightVector' and `FT_Get_MM_WeightVector' are new
|
|
|
|
|
functions limited to Adobe MultiMaster fonts to directly set and
|
|
|
|
|
get the weight vector.
|
2018-09-01 11:01:52 +02:00
|
|
|
|
2019-02-20 12:48:36 +01:00
|
|
|
- Support for Position Independent Code as needed by systems that
|
|
|
|
|
prohibit automatic address fixups, such as BREW, has been
|
|
|
|
|
removed. [Compilation with modern compilers that use flags like
|
|
|
|
|
`-fPIC' or `-fPIE' is not affected.]
|
|
|
|
|
|
2019-02-23 11:21:48 +01:00
|
|
|
- The `ftdump' demo program has new options `-c' and `-C' to
|
|
|
|
|
display charmaps in compact and detailed format, respectively.
|
|
|
|
|
Option `-V' has been removed.
|
|
|
|
|
|
|
|
|
|
- The `ftview', `ftstring', and `ftgrid' demo programs use a new
|
|
|
|
|
command line option `-d' to specify the program window's width,
|
|
|
|
|
height, and color depth.
|
|
|
|
|
|
|
|
|
|
- The `ftview' demo program now displays red boxes for zero-width
|
|
|
|
|
glyphs.
|
|
|
|
|
|
|
|
|
|
- `ftglyph' has limited support to display fonts with
|
|
|
|
|
color-layered glyphs. This will be improved later on.
|
|
|
|
|
|
|
|
|
|
- `ftgrid' can now display bitmap fonts also.
|
|
|
|
|
|
|
|
|
|
- The `ttdebug' demo program has a new option `-f' to select a
|
|
|
|
|
member of a TrueType collection (TTC).
|
|
|
|
|
|
|
|
|
|
- Other various improvements to the demo programs.

II. MISCELLANEOUS
|
|
|
|
|
|
|
|
|
|
- Bug fix: Multiple calls to `FT_Get_MM_Var' returned garbage.
|
|
|
|
|
|
|
|
|
|
- The base extensions `ftlcdfil' and `ftfntfmt' are now part of
|
|
|
|
|
the base module (and thus no longer configurable in file
|
|
|
|
|
`modules.cfg').
|
|
|
|
|
|
* Version 2.9.1 released.
=========================
Tag sources with `VER-2-9-1'.

|
- Emboldening of bitmaps didn't work correctly sometimes, showing
|
|
|
|
|
various artifacts (bug introduced in version 2.8.1).
|
|
|
|
|
|
2018-03-08 06:36:47 +01:00
|
|
|
- Use of the `freetype-config' script to get compilation and
|
|
|
|
|
linking options is deprecated since it doesn't support
|
|
|
|
|
cross-compiling, among other deficiencies. Instead, you should
|
|
|
|
|
use the `pkg-config' interface.
|
|
|
|
|
|
|
|
|
|
The `configure' script no longer installs `freetype-config' by
|
2020-10-10 12:48:18 +02:00
|
|
|
default. For backward compatibility, a new configure option
|
2018-03-08 06:36:47 +01:00
|
|
|
`--enable-freetype-config' is provided that reverts this
|
|
|
|
|
decision.
|
|
|
|
|
|
* Version 2.9.1 released.

|
|
- The auto-hinter script ranges have been updated for Unicode 11.
|
|
|
|
|
No support for new scripts have been added, however, with the
|
|
|
|
|
exception of Georgian Mtavruli.
|
|
|
|
|
|
|
|
|
|
- Support for cmake has been improved.

|
Code as needed by systems that prohibit automatic address
|
|
|
|
|
fixups, such as BREW. [Compilation with modern compilers that

CHANGES BETWEEN 2.8.1 and 2.9 (2018-Jan-08)
|
2017-12-30 20:50:50 +01:00
|
|
|
|
|
|
|
|
I. IMPORTANT BUG FIXES
|
|
|
|
|
|
|
|
|
|
- Advance width values of variation fonts were often wrong.
|
|
|
|
|
|
|
|
|
|
- More fixes for variation font support; you should update to this
|
|
|
|
|
version if you want to support them.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
II. IMPORTANT CHANGES
|
|
|
|
|
|
|
|
|
|
- As a GSoC project, Ewald Hew extended the new (Adobe) CFF engine
|
|
|
|
|
to handle Type 1 fonts also, thus greatly improving the
|
|
|
|
|
rendering of this format. This is the new default. The old
|
|
|
|
|
engine is still available if the configuration macro
|
|
|
|
|
`T1_CONFIG_OPTION_OLD_ENGINE' gets defined; using the
|
|
|
|
|
`hinting-engine' property of the `type1' driver module you can
|
|
|
|
|
then switch between the two engines.
|
|
|
|
|
|
|
|
|
|
- A new function, `FT_Set_Named_Instance', can be used to set or
|
|
|
|
|
change the current named instance.
|
|
|
|
|
|
|
|
|
|
- Starting with this FreeType version, resetting variation
|
|
|
|
|
coordinates will return to the currently selected named
|
|
|
|
|
instance. Previously, FreeType returned to the base font (i.e.,
|
|
|
|
|
no instance set).
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
III. MISCELLANEOUS
|
|
|
|
|
|
|
|
|
|
- The `face_flags' field of the `FT_Face' structure has a new bit,
|
|
|
|
|
`FT_FACE_FLAG_VARIATION', which is set if a variation font has
|
|
|
|
|
been altered with `FT_Set_MM_Design_Coordinates',
|
|
|
|
|
`FT_Set_Var_Design_Coordinates', or
|
|
|
|
|
`FT_Set_Var_Blend_Coordinates'.
|
|
|
|
|
|
|
|
|
|
- If the current face is a named instance, the new macro
|
|
|
|
|
`FT_IS_NAMED_INSTANCE' returns true.
|
|
|
|
|
|
|
|
|
|
- `FT_IS_VARIATION' is a new macro that returns true whenever a
|
|
|
|
|
face object has been altered by `FT_Set_MM_Design_Coordinates',
|
|
|
|
|
`FT_Set_Var_Design_Coordinates', or
|
|
|
|
|
`FT_Set_Var_Blend_Coordinates'.
|
|
|
|
|
|
|
|
|
|
- Changing the design coordinates of a variation font with
|
|
|
|
|
`FT_Set_Var_Design_Coordinates' or
|
|
|
|
|
`FT_Set_Var_Blend_Coordinates' does not influence the named
|
|
|
|
|
instance index value (only `FT_Set_Named_Instance' does that).
|
|
|
|
|
|
|
|
|
|
- Special PostScript names for named instances are only returned
|
|
|
|
|
if the named instance is set with `FT_Set_Named_Instance' (and
|
|
|
|
|
the font has corresponding entries in its `fvar' table). If
|
|
|
|
|
`FT_IS_VARIATION' returns true, the algorithmically derived
|
|
|
|
|
PostScript name is provided, not looking up special entries for
|
|
|
|
|
named instances.
|
|
|
|
|
|
2018-01-06 08:39:36 +01:00
|
|
|
- A new function `FT_Done_MM_Var' is provided to free the memory
|
|
|
|
|
returned in a call to `FT_Get_MM_Var'.
|
|
|
|
|
|
2017-12-30 20:50:50 +01:00
|
|
|
- On platforms using the `configure' script, the installed
|
|
|
|
|
`ftoption.h' file now correctly reflects configuration options
|
|
|
|
|
like `--with-harfbuzz'.
|
|
|
|
|
|
|
|
|
|
- Better support to build FreeType as a DLL on Windows using
|
|
|
|
|
Visual C.
|
|
|
|
|
|
|
|
|
|
- All data specific to driver modules is now collected in a single
|
|
|
|
|
file, `FT_DRIVER_H'. Consequently, the macros
|
|
|
|
|
`FT_AUTOHINTER_H', `FT_CFF_DRIVER_H', `FT_TRUETYPE_DRIVER_H',
|
|
|
|
|
and `FT_PCF_DRIVER_H' still work but are deprecated.
|
|
|
|
|
|
|
|
|
|
- Some fuzzer fixes to better reject malformed fonts.
|
|
|
|
|
|
2017-12-31 11:16:36 +01:00
|
|
|
- The `ftbench' demo program has a new test for opening a new face
|
|
|
|
|
and loading some glyphs.
|
|
|
|
|
|
|
|
|
|
- The `ftbench' demo program has a new option `-j' to specify the
|
|
|
|
|
last glyph index to be used in the tests.
|
|
|
|
|
|
|
|
|
|
- The `ftgrid' demo program has a new option `-n' to suppress
|
|
|
|
|
display of named instances of variation fonts.
|
|
|
|
|
|
|
|
|
|
- The `ttdebug' demo program can now show a stack trace (key `K')
|
|
|
|
|
and switch between hexadecimal and decimal display of integers
|
|
|
|
|
(key `I').

CHANGES BETWEEN 2.8 and 2.8.1 (2017-Sep-16)
|
2017-08-01 09:34:24 +02:00
|
|
|
|
|
|
|
|
I. IMPORTANT BUG FIXES
|
|
|
|
|
|
|
|
|
|
- B/W hinting of TrueType fonts didn't work properly if
|
|
|
|
|
interpreter version 38 or 40 was selected.
|
|
|
|
|
|
|
|
|
|
- Some severe problems within the handling of TrueType Variation
|
|
|
|
|
Fonts were found and fixed.
|
|
|
|
|
|
2017-08-10 12:56:50 +02:00
|
|
|
- Function `FT_Set_Var_Design_Coordinates' didn't correctly handle
|
|
|
|
|
the case with less input coordinates than axes.
|
|
|
|
|
|
2017-08-01 09:34:24 +02:00
|
|
|
|
2017-08-14 05:08:39 +02:00
|
|
|
II. IMPORTANT CHANGES
|
|
|
|
|
|
2017-10-02 06:09:50 +02:00
|
|
|
- By default, FreeType now offers high quality LCD-optimized
|
|
|
|
|
output without resorting to ClearType techniques of resolution
|
|
|
|
|
tripling and filtering. In this method, called Harmony, each
|
|
|
|
|
color channel is generated separately after shifting the glyph
|
|
|
|
|
outline, capitalizing on the fact that the color grids on LCD
|
|
|
|
|
panels are shifted by a third of a pixel. This output is
|
2017-08-14 05:08:39 +02:00
|
|
|
indistinguishable from ClearType with a light 3-tap filter.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
III. MISCELLANEOUS
|
2017-08-01 09:34:24 +02:00
|
|
|
|
2017-08-05 18:22:17 +02:00
|
|
|
- Using the new function `FT_Get_Var_Axis_Flags', an application
|
|
|
|
|
can access the `flags' field of a variation axis (introduced in
|
|
|
|
|
OpenType version 1.8.2)
|
|
|
|
|
|
2017-08-01 09:34:24 +02:00
|
|
|
- More sanity checks.
|
|
|
|
|
|
2017-08-06 06:35:19 +02:00
|
|
|
- The internal representation of buffers for LCD rendering has
|
|
|
|
|
changed (to be more precise, the amount of padding gets computed
|
|
|
|
|
differently). Applications that use the FreeType API are not
|
|
|
|
|
affected.
|
|
|
|
|
|
2017-08-10 12:56:50 +02:00
|
|
|
- To reset all design axis values of a variation font to its
|
|
|
|
|
default values you can now say
|
|
|
|
|
|
|
|
|
|
error = FT_Set_Var_Design_Coordinates( face, 0, NULL );
|
|
|
|
|
|
|
|
|
|
This also works with functions `FT_Set_MM_Design_Coordinates'
|
|
|
|
|
and `FT_Set_MM_Blend_Coordinates'.
|
|
|
|
|
|
2017-08-11 07:11:43 +02:00
|
|
|
- FreeType now synthesizes a missing Unicode cmap for (older)
|
|
|
|
|
TrueType fonts also if glyph names are available.
|
|
|
|
|
|
2017-09-05 15:28:21 +02:00
|
|
|
- FreeType has improved handling of BDF fonts without the
|
|
|
|
|
`POINT_SIZE', `RESOLUTION_X', or `RESOLUTION_Y' properties; the
|
|
|
|
|
library now uses the values of the `SIZE' keyword if they are
|
|
|
|
|
missing. Previously, `SIZE' was completely ignored, and
|
|
|
|
|
FreeType used heuristic values instead.
|
|
|
|
|
|
2017-09-05 23:02:04 +02:00
|
|
|
- Multiple calls to `FT_Bitmap_Convert' do work now as advertised.
|
|
|
|
|
Previously, they failed with an assertion error if there was an
|
|
|
|
|
empty bitmap between non-empty ones.
|
|
|
|
|
|
2017-09-09 19:01:11 +02:00
|
|
|
- The warping option has moved from `light' to `normal' hinting
|
|
|
|
|
where it replaces the original hinting algorithm. The `light'
|
|
|
|
|
mode is now always void of any hinting in x-direction.
|
2017-09-09 03:34:47 +02:00
|
|
|
|
2017-09-09 06:31:03 +02:00
|
|
|
- 16bit compiler support is now officially ended. We didn't
|
2017-09-16 04:23:01 +02:00
|
|
|
provide any maintenance since many years, and given that there
|
2017-09-09 06:31:03 +02:00
|
|
|
were no error or problem reports either it seems that it is no
|
|
|
|
|
longer needed.
|
|
|
|
|
|
2017-10-02 06:09:50 +02:00
|
|
|
- The `ftgrid' demo program can now toggle the display of grid
|
|
|
|
|
lines with the `G' key.

I. IMPORTANT CHANGES
|
|
|
|
|
|
2017-05-02 12:32:19 +02:00
|
|
|
- Support for OpenType Variation Fonts is now complete. The last
|
|
|
|
|
missing part was handling the `VVAR' and `MVAR' tables, which is
|
|
|
|
|
available with this release.
|
2017-04-08 17:58:57 +02:00
|
|
|
|
2017-02-20 09:58:43 +01:00
|
|
|
- A new function `FT_Face_Properties' allows the control of some
|
|
|
|
|
module and library properties per font. Currently, the
|
|
|
|
|
following properties can be handled: stem darkening, LCD filter
|
|
|
|
|
weights, and the random seed for the `random' CFF operator.
|
|
|
|
|
|
2019-02-23 11:21:48 +01:00
|
|
|
- The PCF change to show more `colorful' family names (introduced
|
2017-01-09 11:30:32 +01:00
|
|
|
in version 2.7.1) was too radical; it can now be configured with
|
|
|
|
|
PCF_CONFIG_OPTION_LONG_FAMILY_NAMES at compile time. If
|
|
|
|
|
activated, it can be switched off at run time with the new pcf
|
|
|
|
|
property `no-long-family-names'. If the `FREETYPE_PROPERTIES'
|
|
|
|
|
environment variable is available, you can say
|
|
|
|
|
|
|
|
|
|
FREETYPE_PROPERTIES=pcf:no-long-family-names=1
|
|
|
|
|
|
2017-05-11 00:28:05 +02:00
|
|
|
- Support for the following scripts has been added to the
|
|
|
|
|
auto-hinter.

II. IMPORTANT BUG FIXES
|
|
|
|
|
|
2017-05-02 12:32:19 +02:00
|
|
|
- `Light' auto-hinting mode no longer uses TrueType metrics for
|
|
|
|
|
TrueType fonts. This bug was introduced in version 2.4.6,
|
|
|
|
|
causing horizontal scaling also. Almost all GNU/Linux
|
|
|
|
|
distributions (with Fedora as a notable exception) disabled the
|
|
|
|
|
corresponding patch for good reasons; chances are thus high that
|
|
|
|
|
you won't notice a difference.
|
|
|
|
|
|
|
|
|
|
If optical backward compatibility for legacy applications is
|
|
|
|
|
necessary, you might enable the AF_CONFIG_OPTION_TT_SIZE_METRICS
|
|
|
|
|
configuration option. However, it is strongly recommended to
|
|
|
|
|
avoid that, adjusting font sizes instead.
|
|
|
|
|
|
2017-07-12 10:48:41 +02:00
|
|
|
- Global size metrics values in the `FT_Size_Metrics' structure
|
|
|
|
|
can be different for TrueType fonts. Reason is that in older
|
|
|
|
|
FreeType versions the metrics were rounded differently to
|
|
|
|
|
integer pixels compared to all other font formats, yielding an
|
|
|
|
|
inconsistent behaviour if you used non-native hinting. Starting
|
|
|
|
|
with this version, global size metrics for TrueType fonts are
|
|
|
|
|
handled the same as other font formats: `ascender' gets rounded
|
|
|
|
|
up, `descender' gets rounded down, `height' gets normally
|
|
|
|
|
rounded, and `max_advance' gets normally rounded, too.
|
|
|
|
|
|
|
|
|
|
If you need more precise values of (global) ascender, descender,
|
|
|
|
|
height, or `max_advance', please take the corresponding values
|
|
|
|
|
from the `FT_Face' structure and scale them manually.
|
|
|
|
|
|
2017-04-08 17:58:57 +02:00
|
|
|
- If a TrueType font gets loaded with FT_LOAD_NO_HINTING, FreeType
|
|
|
|
|
now scales the font linearly again (bug introduced in version
|
|
|
|
|
2.4.6).
|
|
|
|
|
|
2017-04-27 13:25:58 +02:00
|
|
|
- CVE-2017-8105, CVE-2017-8287: Older FreeType versions have
|
|
|
|
|
out-of-bounds writes caused by heap-based buffer overflows
|
|
|
|
|
related to Type 1 fonts.

III. MISCELLANEOUS
|
2017-01-23 12:53:18 +01:00
|
|
|
|
|
|
|
|
- A new function `FT_Set_Default_Properties' has been added to
|
|
|
|
|
parse the `FREETYPE_PROPERTIES' environment variable
|
|
|
|
|
(previously, it was internal only). `FT_Init_FreeType' always
|
|
|
|
|
call this function, but `FT_New_Library' does not (similar to
|
|
|
|
|
`FT_Add_Default_Modules').
|
|
|
|
|
|
2017-01-24 17:00:36 +01:00
|
|
|
- To be in sync with OpenType version 1.7 and newer, macros
|
|
|
|
|
|
|
|
|
|
FT_PARAM_TAG_IGNORE_PREFERRED_FAMILY,
|

The old macro names are deprecated (but still available).
|
|
|
|
|
|
2017-01-26 21:41:38 +01:00
|
|
|
- Support for SFNT `name' tables has been improved.
|
|
|
|
|
|
2017-01-27 00:06:52 +01:00
|
|
|
. Format 1 `name' tables are now supported. Use new function
|
|
|
|
|
`FT_Get_Sfnt_LangTag' to access associated language tags.

|
|
|
|
2017-01-27 08:45:46 +01:00
|
|
|
. Language, encoding, and name IDs have been updated to OpenType
|
2017-01-27 00:06:52 +01:00
|
|
|
version 1.8.1.
|
2017-01-26 21:41:38 +01:00
|
|
|
|
2017-02-20 09:58:43 +01:00
|
|
|
- The new CFF engine now handles the `random' operator. All CFF
|
|
|
|
|
opcodes are now supported.
|
|
|
|
|
|
|
|
|
|
- The CFF module has a new property `random-seed' to control the
|
|
|
|
|
pseudo-random number generation for the `random' operator.
|
|
|
|
|
|
2017-02-04 20:30:40 +01:00
|
|
|
- The `freetype-config' script is now a wrapper of `pkg-config' if
|
|
|
|
|
this program is available in the path.
|
|
|
|
|
|
2017-04-08 17:58:57 +02:00
|
|
|
- FT_LOAD_TARGET_LCD is now a variant of FT_LOAD_TARGET_LIGHT;
|
|
|
|
|
this should provide better rendering results.
|
|
|
|
|
|
2018-02-17 10:34:47 +01:00
|
|
|
- A mode to display light auto-hinting with subpixel positioning

I. IMPORTANT CHANGES
|
|
|
|
|
|
2016-12-27 10:20:23 +01:00
|
|
|
- Support for the new CFF2 font format as introduced with OpenType
|
|
|
|
|
1.8 has been contributed by Dave Arnolds from Adobe.
|
|
|
|
|
|
|
|
|
|
- Preliminary support for variation fonts as specified in OpenType
|
|
|
|
|
1.8 (in addition to the already existing support for Adobe's MM
|
|
|
|
|
and Apple's GX formats). Dave Arnolds contributed handling of
|
|
|
|
|
advance width change variation; more will come in the next
|
|
|
|
|
version.

II. IMPORTANT BUG FIXES
|
|
|
|
|
|
2016-10-08 19:20:33 +02:00
|
|
|
- Handling of raw CID fonts was partially broken (bug introduced
|
|
|
|
|
in 2.6.4).
|
|
|
|
|
|
2017-04-26 09:35:39 +02:00
|
|
|
- CVE-2016-10328: Older FreeType versions had an out-of-bounds
|
|
|
|
|
write caused by a heap-based buffer overflow related to the CFF
|
|
|
|
|
fonts.

III. MISCELLANEOUS
|
|
|
|
|
|
|
|
|
|
- Some limits for TrueType bytecode execution have been tightened
|
|
|
|
|
to speed up FreeType's handling of malformed fonts, in
|
|
|
|
|
particular to quickly abort endless loops.
|
|
|
|
|
|
|
|
|
|
- The number of twilight points can no longer be set to an
|
|
|
|
|
arbitrarily large value.
|
|
|
|
|
|
|
|
|
|
- The total number of jump opcode instructions (like JMPR) with
|
|
|
|
|
negative arguments is dynamically restricted; the same holds
|
|
|
|
|
for the total number of iterations in LOOPCALL opcodes.
|
|
|
|
|
|
|
|
|
|
The dynamic limits are based on the number of points in a glyph
|
|
|
|
|
and the number of CVT entries. Please report if you encounter a
|
|
|
|
|
font where the selected values are not adequate.
|
|
|
|
|
|
2019-02-23 11:21:48 +01:00
|
|
|
- PCF family names are made more `colorful'; they now include the
|
2016-09-30 08:11:52 +02:00
|
|
|
foundry and information whether they contain wide characters.
|
|
|
|
|
For example, you no longer get `Fixed' but rather `Sony Fixed'
|
|
|
|
|
or `Misc Fixed Wide'.
|
|
|
|
|
|
2016-10-26 16:00:00 +02:00
|
|
|
- A new function `FT_Get_Var_Blend_Coordinates' (with its alias
|
|
|
|
|
name `FT_Get_MM_Blend_Coordinates') to retrieve the normalized
|
|
|
|
|
blend coordinates of the currently selected variation instance
|
|
|
|
|
has been added to the Multiple Masters interface.
|
|
|
|
|
|
2016-12-27 10:20:23 +01:00
|
|
|
- A new function `FT_Get_Var_Design_Coordinates' to retrieve the
|
|
|
|
|
design coordinates of the currently selected variation instance
|
|
|
|
|
has been added to the Multiple Masters interface.
|
|
|
|
|
|
2016-11-06 12:32:51 +01:00
|
|
|
- A new load flag `FT_LOAD_BITMAP_METRICS_ONLY' to retrieve bitmap
|
|
|
|
|
information without loading the (embedded) bitmap itself.
|
|
|
|
|
|
2016-12-27 10:20:23 +01:00
|
|
|
- Retrieving advance widths from bitmap strikes (using
|
|
|
|
|
`FT_Get_Advance' and `FT_Get_Advances') have been sped up.
|
|
|
|
|
|
|
|
|
|
- The usual round of fuzzer fixes to better reject malformed
|
|
|
|
|
fonts.
|
|
|
|
|
|
|
|
|
|
- The `ftmulti' demo program can now switch engines with key `H'.
|
|
|
|
|
|
|
|
|
|
- The `ftstring' demo program can now show some built-in,
|
|
|
|
|
non-latin sample strings (to be selected with the TAB key).
|
|
|
|
|
|
|
|
|
|
- The `ftview' demo program can now switch between a font's
|
|
|
|
|
charmaps using the TAB key.

CHANGES BETWEEN 2.6.5 and 2.7 (2016-Sep-08)

|
|
|

|
|
|
I. IMPORTANT CHANGES
|
|
|
|
|
|
|
|
|
|
- As announced earlier, the 2.7.x series now uses the new subpixel
|
|
|
|
|
hinting mode as the default, emulating a modern version of
|
|
|
|
|
ClearType.
|
|
|
|
|
|
|
|
|
|
This change inevitably leads to different rendering results, and
|
|
|
|
|
you might change the `TT_CONFIG_OPTION_SUBPIXEL_HINTING'
|
|
|
|
|
configuration option to adapt it to your taste (or use the new
|
|
|
|
|
`FREETYPE_PROPERTIES' environment variable). See the
|
|
|
|
|
corresponding entry below for version 2.6.4, which gives more
|
|
|
|
|
information.
|
|
|
|
|
|
|
|
|
|
- A new option `FT_CONFIG_OPTION_ENVIRONMENT_PROPERTIES' has been
|
|
|
|
|
introduced. If set (which is the default), an environment
|
|
|
|
|
variable `FREETYPE_PROPERTIES' can be used to control driver
|
|
|
|
|
properties. Example:
|
|
|
|
|
|
|
|
|
|
FREETYPE_PROPERTIES=truetype:interpreter-version=35 \
|
|
|
|
|
cff:no-stem-darkening=1 \
|
|
|
|
|
autofitter:warping=1
|
|
|
|
|
|
|
|
|
|
This allows to select, say, the subpixel hinting mode at runtime
|
|
|
|
|
for a given application. See file `ftoption.h' for more.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
II. IMPORTANT BUG FIXES
|
2016-07-14 10:25:20 +02:00
|
|
|
|
|
|
|
|
- After loading a named instance of a GX variation font, the
|
|
|
|
|
`face_index' value in the returned `FT_Face' structure now
|
|
|
|
|
correctly holds the named instance index in the upper 16bits as
|
|
|
|
|
documented.
|
|
|
|
|
|

III. MISCELLANEOUS
|
2016-07-14 15:01:55 +02:00
|
|
|
|
2016-09-02 08:24:01 +02:00
|
|
|
- A new macro `FT_IS_NAMED_INSTANCE' to test whether a given face
|
2016-07-14 15:01:55 +02:00
|
|
|
is a named instance.
|
|
|
|
|
|
2016-09-02 08:24:01 +02:00
|
|
|
- More fixes to GX font handling.
|
|
|
|
|
|
|
|
|
|
- Apple's `GETVARIATION' bytecode operator (needed for GX
|
|
|
|
|
variation font support) has been implemented.
|
|
|
|
|
|
|
|
|
|
- Another round of fuzzer fixes, mainly to reject invalid fonts
|
|
|
|
|
faster.
|
|
|
|
|
|
|
|
|
|
- Handling of raw CID fonts was broken (bug introduced in version
|
|
|
|
|
2.6.4).

- The new subpixel hinting mode is now disabled by default; it
|
|
|
|
|
will be enabled by default in the forthcoming 2.7.x series.
|
|
|
|
|
Main reason for reverting this feature is the principle of least
|
|
|
|
|
surprise: a sudden change in appearance of all fonts (even if
|
|
|
|
|
the rendering improves for almost all recent fonts) should not
|
|
|
|
|
be expected in a new micro version of a series.

I. IMPORTANT CHANGES
|
|
|
|
|
|
|
|
|
|
- A new subpixel hinting mode has been contributed by Nikolaus
|
|
|
|
|
Waxweiler, which is now the default rendering mode for TrueType
|
|
|
|
|
fonts. It implements (almost everything of) version 40 of the
|
|
|
|
|
bytecode engine.
|
|
|
|
|
|
|
|
|
|
The existing code base in FreeType (the `Infinality code') was
|
|
|
|
|
stripped to the bare minimum and all configurability removed in
|
|
|
|
|
the name of speed and simplicity. The configurability was
|
|
|
|
|
mainly aimed at legacy fonts like Arial, Times New Roman, or
|
|
|
|
|
Courier. [Legacy fonts are fonts that modify vertical stems to
|
|
|
|
|
achieve clean black-and-white bitmaps.] The new mode focuses on
|
|
|
|
|
applying a minimal set of rules to all fonts indiscriminately so
|
|
|
|
|
that modern and web fonts render well while legacy fonts render
|
|
|
|
|
okay.
|
|
|
|
|
|
|
|
|
|
Activation of the subpixel hinting support can be controlled
|
|
|
|
|
with the `TT_CONFIG_OPTION_SUBPIXEL_HINTING' configuration
|
|
|
|
|
option at compile time: If set to value 1, you get the old
|
|
|
|
|
Infinality mode (which was never the default due to its
|
|
|
|
|
slowness). Value 2 activates the new subpixel hinting mode, and
|
|
|
|
|
value 3 activates both. The default is value 2.
|
|
|
|
|
|
|
|
|
|
At run time, you can select the subpixel hinting mode with the
|
|
|
|
|
`interpreter-version' property (provided you have compiled in
|
|
|
|
|
the corresponding hinting mode); see `ftttdrv.h' for more.
|
|
|
|
|
|
|
|
|
|
- Support for the following scripts has been added to the
|
|
|
|
|
auto-hinter.
|
|
|
|
|
|
|
|
|
|
Armenian, Cherokee, Ethiopic, Georgian, Gujarati, Gurmukhi,
|
|
|
|
|
Malayalam, Sinhala, Tamil
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
II. MISCELLANEOUS
|
|
|
|
|
|
|
|
|
|
- Type 42 fonts as created by LilyPond are now supported.
|
|
|
|
|
|
2017-01-18 05:45:08 +01:00
|
|
|
- Minor rendering improvements in the auto-hinter.

|
|
|
|
|
|
- For experimental reasons, the old CFF engine now supports all
|
|
|
|
|
CFF operators except `random', including the deprecated Multiple
|
|
|
|
|
Masters instructions. This allows the display of fonts like
|
|
|
|
|
`ITCGaramondMM-It.otf' (without font variations, though).
|
|
|
|
|
|
|
|
|
|
- Another round of fixes to improve handling of invalid fonts.
|
|
|
|
|
|
|
|
|
|
- The `ftgrid' demo program now displays the rendered pixels also;
|
|
|
|
|
this can be switched off with the `b' key. Selection of various
|
|
|
|
|
LCD filtering modes can be done with the `L' key.
|
|
|
|
|
|
|
|
|
|
- The demo programs have been extended to allow selection of all
|
|
|
|
|
available TrueType bytecode engines.
|
|
|
|
|
|
|
|
|
|
- A very early beta version of a new, Qt based demo program called
|
|
|
|
|
`ftinspect' is part of the source code bundle; it will
|
|
|
|
|
eventually supersede the other demo programs. Currently, you
|
|
|
|
|
have to compile it manually with `qmake; make'; note that many
|
|
|
|
|
features are still missing.

CHANGES BETWEEN 2.6.2 and 2.6.3 (2016-Feb-08)
|
2016-02-08 19:51:40 +01:00
|
|
|
|
|
|
|
|
I. IMPORTANT CHANGES
|
|
|
|
|
|
|
|
|
|
- Khmer, Myanmar, Bengali, and Kannada script support has been
|
|
|
|
|
added to the auto-hinter.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
II. MISCELLANEOUS
|
|
|
|
|
|
|
|
|
|
- Better support of Indic scripts like Devanagari by using a
|
|
|
|
|
top-to-bottom hinting flow.
|
|
|
|
|
|
|
|
|
|
- All FreeType macros starting with two underscores have been
|
|
|
|
|
renamed to avoid a violation of both the C and C++ standards.
|
|
|
|
|
Example: Header macros of the form `__FOO_H__' are now called
|
|
|
|
|
`FOO_H_'. In most cases, this should be completely transparent
|
|
|
|
|
to the user. The exception to this is `__FTERRORS_H__', which
|
|
|
|
|
must be sometimes undefined by the user to get FreeType error
|
|
|
|
|
strings: Both this form and the new `FTERRORS_H_' macro are
|
2017-05-03 23:54:29 +02:00
|
|
|
accepted for backward compatibility.
|
2016-02-08 19:51:40 +01:00
|
|
|
|
|
|
|
|
- Minor improvements mainly to the Type 1 driver.
|
|
|
|
|
|
|
|
|
|
- The new CFF engine now supports all Type 2 operators except
|
|
|
|
|
`random'.
|
|
|
|
|
|
|
|
|
|
- The macro `_STANDALONE_', used for compiling the B/W and smooth
|
|
|
|
|
rasterizers as stand-alone modules, has been renamed to
|
|
|
|
|
`STANDALONE_', since macro names starting with an underscore and
|
|
|
|
|
followed by an uppercase letter are reserved in both C and C++.
|
|
|
|
|
|
|
|
|
|
- Function `FT_Library_SetLcdFilterWeights' now also activates
|
|
|
|
|
custom LCD filter weights (instead of just adjusting them).
|
|
|
|
|
|
|
|
|
|
- Support for `unpatented hinting' has been completely removed:
|
|
|
|
|
Consequently, the two functions `FT_Face_CheckTrueTypePatents'
|
|
|
|
|
and `FT_Face_SetUnpatentedHinting' now return always false,
|
|
|
|
|
doing nothing.
|
|
|
|
|
|
|
|
|
|
- The `ftgamma' demo program has been modernized; the gamma grid
|
|
|
|
|
display has been moved from `ftview' to this program.
|
|
|
|
|
|
2016-02-09 08:05:55 +01:00
|
|
|
- In `ftview', it is now possible to cycle through the available
|
|
|
|
|
LCD filtering modes.

|
|
properties. This is an experimental feature contributed by
|
|
|
|
|
Nikolaus Waxweiler, and the interface might change in a future
|
|
|
|
|
release.
|
2015-11-21 13:12:06 +01:00
|
|
|
|
|
|
|
|
- By default, stem darkening is now switched off (for both the CFF
|
|
|
|
|
engine and the auto-hinter). The main reason is that you need
|
|
|
|
|
linear alpha blending and gamma correction to get correct
|
|
|
|
|
rendering results, and the latter is not yet available in most
|
|
|
|
|
freely available rendering stacks like X11. Applying stem
|
|
|
|
|
darkening without proper gamma correction leads to far too dark
|
|
|
|
|
rendering results.
|
|
|
|
|
|
|
|
|
|
- The meaning of `FT_RENDER_MODE_LIGHT' has been slightly
|
|
|
|
|
modified. It now essentially means `no hinting along the
|
|
|
|
|
horizontal axis'; in particular, no change of glyph advance
|
|
|
|
|
widths. Consequently, the auto-hinter is used for all scalable
|
|
|
|
|
font formats except for CFF. It is planned that other
|
|
|
|
|
font-specific rendering engines (TrueType, Type 1) will follow.

|
|
- The default LCD filter has been changed to be normalized and
|
|
|
|
|
color-balanced.
|
|
|
|
|
|
2015-11-21 13:12:06 +01:00
|
|
|
- For better compatibility with FontConfig, function
|
|
|
|
|
`FT_Library_SetLcdFilter' accepts a new enumeration value
|
|
|
|
|
`FT_LCD_FILTER_LEGACY1' (which has the same meaning as
|
|
|
|
|
`FT_LCD_FILTER_LEGACY').
|
|
|
|
|
|
|
|
|
|
- A large number of bugs have been detected by using the libFuzzer
|
|
|
|
|
framework, which should further improve handling of invalid
|
|
|
|
|
fonts. Thanks again to Kostya Serebryany and Bungeman!
|
|
|
|
|
|
|
|
|
|
- `TT_CONFIG_OPTION_MAX_RUNNABLE_OPCODES', a new configuration
|
|
|
|
|
option, controls the maximum number of executed opcodes within a
|
|
|
|
|
bytecode program. You don't want to change this except for very
|
|
|
|
|
special situations (e.g., making a library fuzzer spend less
|
|
|
|
|
time to handle broken fonts).
|
|
|
|
|
|
|
|
|
|
- The smooth renderer has been made faster.
|
|
|
|
|
|
2018-02-17 10:34:47 +01:00
|
|
|
- The `ftstring' demo program now supports subpixel rendering; use
|
|
|
|
|
key `l' to cycle through the LCD modes.

Fix Savannah bug #45097.
We no longer `pollute' the namespace of possible header file names;
instead we move `ft2build.h' up by one level so that it gets
installed in the default include directory (e.g.,
/usr/local/include). After this commit, only `ft2build.h' stays in
the compiler's include path.
No visible changes for the user who follows the standard FreeType
header inclusion rules.

- A new load flag `FT_LOAD_COMPUTE_METRICS' has been added; it
|
2015-10-01 17:39:31 +02:00

makes FreeType ignore pre-computed metrics, as needed by font

Fix Savannah bug #45097.
We no longer `pollute' the namespace of possible header file names;
instead we move `ft2build.h' up by one level so that it gets
installed in the default include directory (e.g.,
/usr/local/include). After this commit, only `ft2build.h' stays in
the compiler's include path.
No visible changes for the user who follows the standard FreeType
header inclusion rules.
* include/*: Move to ...
* include/freetype2/*: This directory, except `ft2build.h'.
* CMakeLists.txt (PUBLIC_HEADERS, PUBLIC_CONFIG_HEADERS,
PRIVATE_HEADERS), Jamfile (HDRMACRO, RefDoc), autogen.sh: Updated.
* builds/amiga/include/config/ftconfig.h, builds/freetype.mk
(PUBLIC_DIR), builds/symbian/bld.inf, builds/toplevel.mk (work),
builds/unix/install.mk (install, uninstall),
builds/unix/freetype2.in: Updated.
* builds/unix/freetype-config.in: Updated.
Emit -I directory only if it is not `/usr/include'.

I. IMPORTANT CHANGES
|
2015-01-14 20:06:19 +01:00
|
|
|
|
|
|
|
|
- Behdad Esfahbod contributed code for improved thread-safety,
|
|
|
|
|
which results in the following model.
|
|
|
|
|
|
|
|
|
|
* An `FT_Face' object can only be safely used from one thread at
|
|
|
|
|
a time.
|
|
|
|
|
|
|
|
|
|
* An `FT_Library' object can now be used without modification
|
|
|
|
|
from multiple threads at the same time.
|
|
|
|
|
|
|
|
|
|
* `FT_Face' creation and destruction with the same `FT_Library'
|
|
|
|
|
object can only be done from one thread at a time.
|
|
|
|
|
|
|
|
|
|
One can use a single `FT_Library' object across threads as long
|
|
|
|
|
as a mutex lock is used around `FT_New_Face' and `FT_Done_Face'.
|
|
|
|
|
Any calls to `FT_Load_Glyph' and similar API are safe and do not
|
|
|
|
|
need the lock to be held as long as the same `FT_Face' is not
|
|
|
|
|
used from multiple threads at the same time.
|
|
|
|
|
|
2015-03-10 11:15:15 +01:00
|
|
|
- Thai script support has been added to the auto-hinter.
|
|
|
|
|
|
2015-03-11 16:45:58 +01:00
|
|
|
- Arabic script support has been added to the auto-hinter.
|
|
|
|
|
|
2015-04-28 10:56:19 +02:00
|
|
|
- Following OpenType version 1.7, advance widths and side bearing
|
|
|
|
|
values in CFFs (wrapped in an SFNT structure) are now always
|
2015-04-21 07:51:41 +02:00
|
|
|
taken from the `hmtx' table.
|
|
|
|
|
|
2015-04-28 10:56:19 +02:00
|
|
|
- Following OpenType version 1.7, the PostScript font name of a
|
|
|
|
|
CFF font (wrapped in an SFNT structure) is now always taken from
|
|
|
|
|
the `name' table. This is also true for OpenType Collections
|
|
|
|
|
(i.e., TTCs using CFFs subfonts instead of TTFs), where it may
|
|
|
|
|
have a significant difference.
|
|
|
|
|
|
2015-05-22 22:02:15 +02:00
|
|
|
- Fonts natively hinted for ClearType are now supported, properly
|
|
|
|
|
handling selector index 3 of the INSTCTRL bytecode instruction.
|
|
|
|
|
|
2015-05-31 12:32:11 +02:00
|
|
|
- Major improvements to the GX TrueType variation font handling.

II. MISCELLANEOUS
|
2015-02-25 06:55:00 +01:00
|
|
|
|
2015-04-21 07:51:41 +02:00
|
|
|
- A new auto-hinter property `warping' can switch on and off the
|
|
|
|
|
warping code if this experimental feature is compiled in (by
|
2015-05-31 12:32:11 +02:00
|
|
|
defining the AF_CONFIG_OPTION_USE_WARPER configuration option;
|
|
|
|
|
by default this option is now enabled but warping is switched
|
2015-04-22 11:14:35 +02:00
|
|
|
off).
|
2015-04-21 07:51:41 +02:00
|
|
|
|
|
|
|
|
The AF_CONFIG_OPTION_USE_WARPER option itself is an old feature,
|
|
|
|
|
available since 2006. Warping only works in `light'
|
|
|
|
|
auto-hinting mode. The idea of the code is to slightly scale
|
|
|
|
|
and shift a glyph along the non-hinted dimension (which is
|
|
|
|
|
usually the horizontal axis) so that as much of its segments are
|
|
|
|
|
aligned (more or less) to the grid. To find out a glyph's
|
|
|
|
|
optimal scaling and shifting value, various parameter
|
|
|
|
|
combinations are tried and scored.
|
|
|
|
|
|
|
|
|
|
See file `ftautoh.h' for more; the demo programs `ftdiff',
|
|
|
|
|
`ftview', and `ftgrid' can toggle warping with key `w'.
|
|
|
|
|
|
2015-02-25 06:55:00 +01:00
|
|
|
- Some fields in the `FTC_ImageTypeRec' structure have been
|
|
|
|
|
changed from signed to unsigned type, which better reflects the
|
|
|
|
|
actual usage. It is also an additional means to protect against
|
|
|
|
|
malformed input.
|
|
|
|
|
|
|
|
|
|
This change doesn't break the ABI; however, it might cause
|
|
|
|
|
compiler warnings.
|
|
|
|
|
|
2015-03-11 07:32:58 +01:00
|
|
|
- Function `FT_Bitmap_New' has been renamed to `FT_Bitmap_Init',
|
2017-05-03 23:54:29 +02:00
|
|
|
since this name better reflects its function. For backward
|
2015-03-10 11:15:15 +01:00
|
|
|
compatibility, the old function name is still available.
|
|
|
|
|
|
2015-03-11 07:32:58 +01:00
|
|
|
- Function `FT_Get_X11_Font_Format' has been renamed to
|
|
|
|
|
`FT_Get_Font_Format', since this name better reflects its
|
2017-05-03 23:54:29 +02:00
|
|
|
function. For backward compatibility, the old function name is
|
2015-03-11 07:32:58 +01:00
|
|
|
still available.
|
|
|
|
|
|
2015-03-11 07:45:05 +01:00
|
|
|
Additionally, the header file macro for this function has been
|
|
|
|
|
renamed to `FT_FONT_FORMATS_H' (the old name `FT_XFREE86_H' is
|
2017-05-03 23:54:29 +02:00
|
|
|
retained for backward compatibility).
|
2015-03-11 07:45:05 +01:00
|
|
|
|
2015-04-21 07:51:41 +02:00
|
|
|
- Various improvements to the `ftgrid' demo program.
|
|
|
|
|
|
2015-05-31 12:32:11 +02:00
|
|
|
. It can now display GX and MM fonts while interactively
|
2015-04-21 07:51:41 +02:00
|
|
|
manipulating the axes (with keys F2, F3, and F4).
|
|
|
|
|
|
|
|
|
|
. Anti-aliasing rendering modes can now be selected (with keys
|
|
|
|
|
F5 and F6).
|
|
|
|
|
|
2015-06-06 23:52:42 +02:00
|
|
|
. The display of point numbers can be toggled with key `D'.
|
|
|
|
|
|
2015-04-21 07:51:41 +02:00
|
|
|
- Various improvements to the `ftdump' demo program.
|
|
|
|
|
|
|
|
|
|
. It now displays information on MM and GX variation axes.
|
|
|
|
|
|
|
|
|
|
. New command line option `-u' makes it output data in utf-8
|
|
|
|
|
encoding.
|
|
|
|
|
|
2015-05-31 12:32:11 +02:00
|
|
|
- The `ftmulti' demo program can now handle up to six MM or GX
|
|
|
|
|
axes.

|
|
|
|
|
|
- More bug fixes related to correct positioning of composite
|
|
|
|
|
glyphs.
|
|
|
|
|
|
|
|
|
|
- Many fixes to better protect against malformed input.

|
II. IMPORTANT CHANGES
|
|
|
|
|
|
|
|
|
|
- FreeType can now use the HarfBuzz library to greatly improve the
|
|
|
|
|
auto-hinting of fonts that use OpenType features: Many glyphs
|
|
|
|
|
that are part of such features but don't have cmap entries are
|
|
|
|
|
now handled properly, for example small caps or superscripts.
|
|
|
|
|
Define the configuration macro FT_CONFIG_OPTION_USE_HARFBUZZ to
|
|
|
|
|
activate HarfBuzz support.
|
|
|
|
|
|
|
|
|
|
You need HarfBuzz version 0.9.19 or newer.
|
|
|
|
|
|
|
|
|
|
Note that HarfBuzz depends on FreeType; this currently causes a
|
|
|
|
|
chicken-and-egg problem that can be solved as follows in case
|
|
|
|
|
HarfBuzz is not yet installed on your system.
|
|
|
|
|
|
|
|
|
|
1. Compile and install FreeType without the configuration
|
|
|
|
|
macro FT_CONFIG_OPTION_USE_HARFBUZZ.
|
|
|
|
|
|
|
|
|
|
2. Compile and install HarfBuzz.
|
|
|
|
|
|
|
|
|
|
3. Define macro FT_CONFIG_OPTION_USE_HARFBUZZ, then compile
|
|
|
|
|
and install FreeType again.
|
|
|
|
|
|
|
|
|
|
With FreeType's `configure' script the procedure boils down to
|
2017-09-08 04:36:02 +02:00
|
|
|
configure, build, and install FreeType, then configure, compile,

|
and install HarfBuzz, then configure, compile, and install
|
|
|
|
|
FreeType again (after executing `make distclean').
|
|
|
|
|
|
|
|
|
|
- All libraries FreeType depends on are now checked using the
|
|
|
|
|
`pkg-config' configuration files first, followed by alternative
|
|
|
|
|
methods.
|
|
|
|
|
|
|
|
|
|
- The new value `auto' for the various `--with-XXX' library
|
|
|
|
|
options (for example `--with-harfbuzz=auto') makes the
|
|
|
|
|
`configure' script automatically link to the libraries it finds.
|
|
|
|
|
This is now the default.
|
|
|
|
|
|
|
|
|
|
- In case FreeType's `configure' script can't find a library, you
|
|
|
|
|
can pass environment variables to circumvent pkg-config, and
|
|
|
|
|
those variables have been harmonized as a consequence of the
|
|
|
|
|
changes mentioned above:
|
|
|
|
|
|
|
|
|
|
LIBZ -> removed; use LIBZ_CFLAGS and LIBZ_LIBS
|
|
|
|
|
LIBBZ2 -> removed; use BZIP2_CFLAGS and BZIP2_LIBS
|
|
|
|
|
LIBPNG_LDFLAGS -> LIBPNG_LIBS
|
|
|
|
|
|
|
|
|
|
`./configure --help' shows all available environment variables.
|
|
|
|
|
|
|
|
|
|
- The `freetype-config' script now understands option `--static'
|
|
|
|
|
to emit static linking information.

I. IMPORTANT BUG FIXES
|
|
|
|
|
|
|
|
|
|
- Improving the display of some broken TrueType fonts introduced a
|
|
|
|
|
bug that made FreeType crash on some popular (but not fully
|
|
|
|
|
conformant) fonts like `ahronbd.ttf'.
|
|
|
|
|
|
|
|
|
|
- Another round of improvements to correct positioning and hinting
|
|
|
|
|
of composite glyphs in TrueType fonts.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
II. MISCELLANEOUS
|
|
|
|
|
|
|
|
|
|
- Version 2.5.1 introduced a bug in handling embedded bitmap
|
|
|
|
|
strikes of TrueType fonts, causing garbage display under some
|
|
|
|
|
circumstances.
|
|
|
|
|
|
|
|
|
|
- The `ftgrid' demo program couldn't be compiled in
|
|
|
|
|
non-development builds.

I. IMPORTANT BUG FIXES
|
|
|
|
|
|
|
|
|
|
- For some WinFNT files, the last glyph wasn't displayed but
|
|
|
|
|
incorrectly marked as invalid.
|
|
|
|
|
|
2013-09-20 07:23:34 +02:00
|
|
|
- The vertical size of glyphs was incorrectly set after a call to
|
|
|
|
|
`FT_GlyphSlot_Embolden', resulting in clipped glyphs.
|
2013-06-28 07:57:32 +02:00
|
|
|
|
2013-10-03 06:16:50 +02:00
|
|
|
- Many fields of the `PCLT' table in SFNT based fonts (if accessed
|
|
|
|
|
with `FT_Get_Sfnt_Table') were computed incorrectly.
|
|
|
|
|
|
2013-11-06 07:14:49 +01:00
|
|
|
- In TrueType fonts, hinting of composite glyphs could sometimes
|
|
|
|
|
deliver incorrect positions of components or even distorted
|
|
|
|
|
shapes.

|
|
|
|
|
fine-tuned with the new `darkening-parameters' property.
|
|
|
|
|
|
2013-06-28 07:59:42 +02:00
|
|
|
- `ftgrid' has been updated to toggle various engines with the `H'
|
|
|
|

`T' shows the twilight point table, key `S' the storage data,
|
|
|
|
|
and key `C' the control value table.
|

|
|
|
uppercase equivalents; for example `q' to quit the program is
|
|
|
|
|
now `Q'.

|
|
|
- Better support of ARMv7 and x86_64 processors.
|
|
|
|
|
|
|
|
|
|
- Apple's `sbix' color bitmap format is now supported.
|
|
|
|
|
|
|
|
|
|
- Improved auto-hinter rendering for many TrueType fonts,
|
|
|
|
|
especially in the range 20-40ppem.
|
|
|
|
|
|
|
|
|
|
- A new face flag `FT_FACE_FLAG_COLOR' has been added (to be
|
|
|
|
|
accessed with the macro `FT_HAS_COLOR').
|
|
|
|
|
|
|
|
|
|
- `FT_Gzip_Uncompress' (modeled after zlib's `uncompress'
|
|
|
|
|
function) has been added; this is a by-product of the newly
|
|
|
|
|
added WOFF support.
|
|
|
|
|
|
2013-10-24 08:50:34 +02:00
|
|
|
- Support for a build with `cmake' has been contributed by John
|
|
|
|
|
Cary <cary@txcorp.com>.
|
|
|
|
|
|
|
|
|
|
- Support for x64 builds with Visual C++ has been contributed by
|
|
|
|
|
Kenneth Miller <kennethadammiller@yahoo.com>
|
|
|
|
|
|
2013-11-01 22:27:27 +01:00
|
|
|
- Manual pages for most demo programs have been added.
|
|
|
|
|
|
2013-11-02 11:36:37 +01:00
|
|
|
- The GETINFO bytecode instruction for TrueType fonts was buggy if
|
|
|
|
|
used to retrieve subpixel hinting information. It was necessary
|
|
|
|
|
to set selector bit 6 to get results for selector bits 7-10,
|
|
|
|
|
which is wrong.
|
|
|
|
|
|
2013-11-06 07:14:49 +01:00
|
|
|
- Improved computation of emulated vertical metrics for TrueType
|
|
|
|
|
fonts.
|
|
|
|
|
|
|
|
|
|
- Fixed horizontal start-up position of vertical phantom points in
|
|
|
|
|
TrueType bytecode.

I. IMPORTANT BUG FIXES
|
|
|
|
|
|
|
|
|
|
- The cache manager function `FTC_Manager_Reset' didn't flush the
|
|
|
|
|
cache.

II. IMPORTANT CHANGES
|
2013-01-11 09:02:22 +01:00
|
|
|
|
Add support for color embedded bitmaps (eg. color emoji).
A new load flag, FT_LOAD_COLOR, makes FreeType load color
embedded-bitmaps, following this draft specification
https://color-emoji.googlecode.com/git/specification/v1.html
which defines two new SFNT tables, `CBDT' and `CBLC' (named and
modeled after `EBDT' and `EBLC', respectively). The color bitmaps
are stored in the new FT_PIXEL_MODE_BGRA format to represent BGRA
pre-multiplied sRGB images. If PNG support is available, PNG color
images as defined in the same proposed specification are supported
also.
Note that color bitmaps are converted to grayscale if client didn't
ask for color.
* builds/unix/configure.raw: Search for libpng.
Add `--without-png' option.
* devel/ftoption.h, include/freetype/config/ftoption.h
(FT_CONFIG_OPTION_USE_PNG): New macro.
* include/freetype/freetype.h (FT_LOAD_COLOR): New load flag.
* include/freetype/ftimage.h (FT_Pixel_Mode): Add
`FT_PIXEL_MODE_BGRA'.
* include/freetype/tttags.h (TTAG_CBDT, TTAG_CBLC): New tags.
* src/base/ftbitmap.c (FT_Bitmap_Embolden): Updated.
(ft_gray_for_premultiplied_srgb_bgra): New function.
(FT_Bitmap_Convert): Handle FT_PIXEL_MODE_BGRA.
* src/sfnt/pngshim.c, src/sfnt/pngshim.h: New files.
* src/sfnt/sfnt.c: Include `pngshim.c'.
* src/sfnt/ttsbit.c: Include FT_BITMAP_H and `pngshim.h'
(tt_face_load_eblc): Load `CBLC'.
(tt_sbit_decoder_init): Load `CBDT'.
(tt_sbit_decoder_alloc_bitmap): Pass load flags to select between
color and grayscale bitmaps.
Set `num_grays'. This is used by `ftview' to choose the blending
algorithm.
(tt_sbit_decoder_load_byte_aligned,
tt_sbit_decoder_load_bit_aligned, tt_sbit_decoder_load_compound,
tt_sbit_decoder_load_image): Pass load flag.
s/write/pwrite/.
Don't call `tt_sbit_decoder_alloc_bitmap'.
Updated.
(tt_sbit_decoder_load_png) [FT_CONFIG_OPTION_USE_PNG]: New function.
(tt_sbit_decoder_load_bitmap): Pass load flag.
Handle new glyph formats 17, 18, and 19.
Call `tt_sbit_decoder_alloc_bitmap'.
Flatten color bitmaps if necessary.
(tt_face_load_sbit_image): Updated.
* src/sfnt/rules.mk (SFNT_DRV_SRC): Add `pngshim.c'.

|
|
|
- As announced in the previous release, the old FreeType CFF
|
|
|
|
|
engine is now disabled by default. It can be conditionally
|
|
|
|
|
compiled by defining the configuration macro
|
|
|
|
|
CFF_CONFIG_OPTION_OLD_ENGINE.
|
|
|
|
|
|
2013-05-10 07:58:47 +02:00
|
|
|
- As announced in the previous release, all code related to macro
|
|
|
|
|
FT_CONFIG_OPTION_OLD_INTERNALS has been removed, thus becoming
|
|
|
|
|
obsolete.

III. MISCELLANEOUS
|
2013-06-03 12:41:58 +02:00
|
|
|
|
|
|
|
|
- The property API (`FT_Property_Get' and `FT_Property_Set') is
|
|
|
|
|
now declared as stable.
|
|
|
|
|
|
2013-06-19 00:25:06 +02:00
|
|
|
The exception, however, are the experimental auto-hinter
|
|
|
|
|
properties `glyph-to-script-map' and `fallback-script' which are
|
|
|
|
|
subject to change in a forthcoming release.
|
|
|
|
|
|
|
|
|
|
- `ftview' has been updated to support color embedded bitmaps; it
|
|
|
|
|
can be toggled on and off with key `c'. The small cache toggle
|
|
|
|
|
is now key `K'.
|
2013-06-03 12:41:58 +02:00
|
|
|
|
|
|
|
|
- It is now possible to control the version of the TrueType
|
|
|
|
|
hinting engine using the new `interpreter-version' property of
|
|
|
|
|
the `truetype' module: Versions 35 and 38 (the default) are
|
|
|
|
|
supported, which roughly corresponds to disable and enable
|
|
|
|
|
subpixel hinting support, respectively.
|
|
|
|
|
|
|
|
|
|
In both `ftview' and `ftdiff', switching between the two
|
|
|
|
|
versions can be done with key `H'. In the `ftbench' demo
|
|
|
|
|
program, command line option `-H' has been extended to activate
|
|
|
|
|
the non-default interpreter version.
|
|
|
|
|
|
2013-06-19 00:25:06 +02:00
|
|
|
- The `ttdebug' program has been further improved. In particular,
|
|
|
|
|
it accepts a new command line option `-H' to select the hinting
|
|
|
|
|
engine.
|
|
|
|
|
|
2014-06-10 06:51:52 +02:00
|
|
|
- `ftdump's verbose option has been renamed to `-V'. For all demo
|
|
|
|
|
programs, `-v' now shows version information.
|
|
|
|
|
|
2013-06-03 12:41:58 +02:00
|
|
|
- Another round of TrueType subpixel hinting fixes.
|
|
|
|
|
|
|
|
|
|
- The `apinames' tool can now create an import file for NetWare.
|
|
|
|
|
|
|
|
|
|
- 64bit compilation of the new CFF engine was buggy.
|
|
|
|
|
|
2013-06-19 00:25:06 +02:00
|
|
|
- Some fixes to improve robustness in memory-tight situations.

|
|
|
- We have another CFF parsing and hinting engine! Written by Dave
|
|
|
|
|
Arnold <darnold@adobe.com>, this work has been contributed by
|
|
|
|
|
Adobe in collaboration with Google. It is vastly superior to
|
|
|
|
|
the old CFF engine, and it will replace it in the next release.
|
|
|
|
|
Right now, it is still off by default, and you have to
|
|
|
|
|
explicitly select it using the new `hinting-engine' property of
|
|
|
|
|
the cff driver:

The code has a (mature) beta status; we encourage all users to
|
|
|
|
|
test it and report any problems.

- The macro FT_CONFIG_OPTION_OLD_INTERNALS is no longer set by
|
|
|
|
|
default. In the next release, we will completely remove the
|
|
|
|
|
associated code. Please update your programs in case you are

II. MISCELLANEOUS
|
|
|
|
|
|
|
|
|
|
- The (top-level) `configure' script now respects the MAKE
|
2017-05-03 23:54:29 +02:00
|
|
|
environment variable to specify a `make' binary. For backward
|
2013-03-21 09:00:27 +01:00
|
|
|
compatibility, GNUMAKE still overrides MAKE, though.
|
|
|
|
|
|
2013-04-27 08:09:35 +02:00
|
|
|
- The `ftview' and `ftdiff' demo programs have been redesigned,
|
|
|
|
|
showing more options permanently on the screen, among other
|
|
|
|
|
minor improvements.
|
|
|
|
|
|
|
|
|
|
- Using the `H' key, it is now possible to select the CFF engine
|
|
|
|
|
in both `ftview' and `ftdiff'.
|
|
|
|
|
|
2013-05-08 10:00:49 +02:00
|
|
|
- The new command line option `-H' for `ftbench' selects the Adobe
|
|
|
|
|
CFF engine.
|
|
|
|
|
|
2013-04-27 08:09:35 +02:00
|
|
|
- It is now possible to directly select the LCD rendering mode
|
|
|
|
|
with the keys `A'-`F' in `ftview'. The key mapping for cycling
|
|
|
|
|
through LCD modes has been changed from `K' and `L' to `k' and
|
|
|
|
|
`l', and toggling custom LCD filtering is no longer mapped to
|
|
|
|
|
key `F' but to key `L'.
|
|
|
|
|
|
|
|
|
|
- In `ftdiff', key `x' toggles between layout modes: Either use
|
|
|
|
|
the advance width (this is new and now the default) or the
|
|
|
|
|
bounding box information to determine line breaks.
|
|
|
|
|
|
|
|
|
|
- For all demo tools, the new command line option `-v' shows the
|
|
|
|
|
version.
|
|
|
|
|
|
|
|
|
|
- For the demo tools with a GUI, the new command line options `-w'
|
|
|
|
|
and `-h' select the width and the height of the output window,
|
|
|
|
|
respectively.
|
|
|
|
|
|
|
|
|
|
- The `ttdebug' program was broken and has been reactivated. Note
|
|
|
|
|
that this program is not compiled by default.

|
|
and which has been integrated.
|
|
|
|
|
|
|
|
|
|
Note that ClearType support is not completely implemented! In
|
|
|
|
|
particular, full support for the options `compatible_widths',
|
|
|
|
|
`symmetrical_smoothing, and `bgr' (via the GETINFO bytecode
|
|
|
|
|
instruction) is missing.
|
|
|
|
|
|
|
|
|
|
Activation of subpixel hinting support can be controlled with
|
|
|
|
|
the `TT_CONFIG_OPTION_SUBPIXEL_HINTING' configuration option; it
|
|
|
|
|
is switched off by default. This feature is still experimental;
|
|
|
|
|
we welcome test reports!
|
|
|
|
|
|
|
|
|
|
- Support for OpenType collections (OTC) has been added.
|
|
|
|
|
|
|
|
|
|
- Pure CFF fonts within an SFNT wrapper are now supported.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
III. MISCELLANEOUS
|
|
|
|
|
|
|
|
|
|
- Minor rendering improvements to the auto-hinter.
|
|
|
|
|
|
|
|
|
|
- `FT_GlyphSlot_Oblique' now uses a shear angle of 12°.
|
|
|
|
|
|
|
|
|
|
- Experimental support to handle `property modules', for example
|
|
|
|
|
to control the behaviour of the auto-hinter. The API consists
|
|
|
|
|
of two new functions, `FT_Property_Set' and `FT_Property_Get'.
|
|
|
|
|
|
|
|
|
|
The code is still subject to change and should not be used for
|
|
|
|
|
production.
|
|
|
|
|
|
|
|
|
|
- The `ftdiff' demo program now supports UTF-8 encoded input files
|
|
|
|
|
for option `-f'.
|
|
|
|
|
|
|
|
|
|
- Using keys `r' and `R', you can now adjust the stroker radius in
|
|
|
|
|
the `ftview' demo program.
|
|
|
|
|
|
|
|
|
|
- Other, minor fixes and improvements.

|
|
similar code in `ftview') has been improved.
|

I. IMPORTANT BUG FIXES
|
|
|
|
|
|
|
|
|
|
- Another round of fixes to better handle invalid fonts. Many of
|
|
|
|
|
them are vulnerabilities (see CVE-2012-1126 up to CVE-2012-1144
|
|
|
|
|
and SA48320) so all users should upgrade.
|
|
|

|
|
|
|
|
II. MISCELLANEOUS
|
2012-02-26 08:46:05 +01:00
|
|
|
|
|
|
|
|
- The `ENCODING -1 <n>' format of BDF fonts is now supported.
|
|
|
|
|
|
|
|
|
|
- For BDF fonts, support for the whole Unicode encoding range has
|
|
|
|
|
been added.
|
|
|
|
|
|
|
|
|
|
- Better TTF support for x_ppem != y_ppem.
|
|
|
|
|
|
|
|
|
|
- `FT_Get_Advances' sometimes returned bogus values.
|
|
|
|
|
|
* Version 2.4.9 released.

|
- For TrueType based fonts, the ascender and descender values were
|
|
|
|
|
incorrect sometimes (off by a pixel if the ppem value was not a
|
|
|
|
|
multiple of 5). Depending on the use you might now experience
|
|
|
|
|
a different layout; the change should result in better, more
|
|
|
|
|
consistent line spacing.
|
|
|
|
|
|
|
|
|
|
- Fix CVE-2011-0226 which causes a vulnerability while handling
|
|
|
|
|
Type 1 fonts.
|
|
|

2011-06-29 10:01:42 +02:00
|
|
|
- BDF fonts containing glyphs with negative values for ENCODING
|
|
|
|
|
were incorrectly rejected. This bug has been introduced in
|
|
|
|
|
FreeType version 2.2.0.
|
|
|
|

- David Bevan contributed a major revision of the FreeType stroker
|
|
|
|
|
code:
|
|
|
|
|
|
|
|
|
|
. The behaviour of FT_STROKER_LINEJOIN_BEVEL has been corrected.
|
|
|
|
|
|
|
|
|
|
. A new line join style, FT_STROKER_LINEJOIN_MITER_FIXED, has
|
|
|
|
|
been introduced to support PostScript and PDF miter joins.
|
|
|
|
|
|
|
|
|
|
. FT_STROKER_LINEJOIN_MITER_VARIABLE has been introduced as an
|
|
|
|
|
alias for FT_STROKER_LINEJOIN_MITER.
|
|
|
|
|
|
|
|
|
|
. Various stroking glitches has been fixed.

I. IMPORTANT BUG FIXES
|
|
|
|
|
|
|
|
|
|
- A rendering regression for second-order Bézier curves has been
|
|
|
|
|
fixed, introduced in 2.4.3.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
II. IMPORTANT CHANGES
|
|
|
|
|
|
|
|
|
|
- If autohinting is not explicitly disabled, FreeType now uses
|
|
|
|
|
the autohinter if a TrueType based font doesn't contain native
|
|
|
|
|
hints.
|
|
|
|
|
|
2011-04-21 08:21:37 +02:00
|
|
|
- The load flag FT_LOAD_IGNORE_GLOBAL_ADVANCE_WIDTH has been made
|
|
|
|
|
redundant and is simply ignored; this means that FreeType now
|
|
|
|
|
ignores the global advance width value in TrueType fonts.

|
|
|
|
|
a font.
|
|
|
|
|
|
2010-12-31 17:47:09 +01:00
|
|
|
- Support for PCF files compressed with bzip2 has been contributed
|
|
|
|
|
by Joel Klinghed. To make this work, the OS must provide a
|
|
|
|
|
bzip2 library.

|
|
Visual Studio 2010 format.
|
|
|
|
|
|
|
|
|
|
- Again some fixes to better handle broken fonts.
|
|
|
|
|
|
|
|

|
|
2011-06-24 13:18:41 +02:00

zones for CJK Ideographs, improving the alignment of horizontal
|
|
|
|
|
stems at the top or bottom edges.

I. IMPORTANT BUG FIXES
|
|
|
|
|
|
|
|
|
|
- UVS support (TrueType/OpenType cmap format 14) support is fixed.
|
|
|
|

II. MISCELLANEOUS
|
|
|
|
|
|
|
|
|
|
- Detect tricky fonts (e.g. MingLiU) by the lengths and checksums
|
|
|
|
|
of Type42-persistent subtables (`cvt ', `fpgm', and `prep') when
|
2010-11-28 15:31:23 +01:00
|
|
|
a TrueType font without family name is given. The previous fix,
|
|
|
|
|
introduced in 2.4.3, was too rigorous, causing many subsetted
|
|
|
|
|
fonts (mainly from PDF files) displayed badly because FreeType
|
|
|
|
|
forced rendering with the TrueType bytecode engine instead of
|
|
|
|
|
the autohinter.
|
|
|
|
|
|
|
|
|
|
- Better support for 64bit platforms.
|
|
|

I. IMPORTANT BUG FIXES
|
|
|
|
|
|
2009-04-30 20:00:22 +02:00
|
|
|
- If all ASCII digits in a font have the same (unscaled) width,
|
2009-04-27 19:40:35 +02:00
|
|
|
the autohinter respects this and won't change it.
|
|
|
|
|
|
2009-07-19 11:18:00 +02:00
|
|
|
- TrueType fonts are now rasterized correctly if the horizontal
|
|
|
|
|
and vertical resolution differ.
|
|
|
|
|
|
|
|
|
|
- Type 1 fonts are now handled with increased precision internally
|
|
|
|
|
to avoid serious rounding issues if non-integral coordinates are
|
|
|
|
|
encountered.
|
|
|
|
|
|
2009-08-27 00:10:56 +02:00
|
|
|
- Horizontally condensed CFF fonts (using the font matrix) were

|
|
|
|
rendered incorrectly. This bug has been introduced after
|
|
|
|
|
release 2.3.5.

|
|
|
|
|
|
2009-06-18 16:07:11 +02:00
|
|
|
- B/W rasterization of well-hinted TrueType fonts at small sizes
|
|
|
|
|
has been greatly improved.
|
|
|
|
|
|
2009-09-23 09:28:48 +02:00

2009-09-23 09:28:48 +02:00
|
|
|
- The 5-levels grayscale mode of the `ftraster' module (which
|
|
|
|
|
FreeType doesn't use by default) was broken since version 2.3.0.
|
|
|
|
|
|
|
|
|
|
- Compilation of the `ftgrays' and `ftraster' modules was broken
|
|
|
|

CHANGES BETWEEN 2.3.9 and 2.3.8
|
|
|
|
|
|
|
|
|
|
I. IMPORTANT BUG FIXES
|
|
|
|
|
|
2009-03-03 22:35:32 +01:00
|
|
|
- Very unfortunately, FreeType 2.3.8 contained a change that broke
|
|
|
|
|
its official ABI. The end result is that programs compiled
|
2009-03-03 21:49:32 +01:00
|
|
|
against previous versions of the library, but dynamically linked
|
2009-03-03 22:35:32 +01:00
|
|
|
to 2.3.8 can experience memory corruption if they call the
|
|
|
|
|
`FT_Get_PS_Font_Info' function.
|
2009-03-03 21:49:32 +01:00
|
|
|
|
2009-03-03 22:35:32 +01:00
|
|
|
We recommend all users to upgrade to 2.3.9 as soon as possible,
|
|
|
|
|
or to downgrade to a previous release of the library if this is
|
2009-03-03 21:49:32 +01:00
|
|
|
not an option.
|
|
|
|
|
|
2009-03-03 22:35:32 +01:00
|
|
|
The origin of the bug is that a new field was added to the
|
|
|
|
|
publicly defined `PS_FontInfoRec' structure. Unfortunately,
|
|
|
|
|
objects of this type can be stack or heap allocated by callers
|
|
|
|
|
of `FT_Get_PS_Font_Info', resulting in a memory buffer
|
|
|
|
|
overwrite with its implementation in 2.3.8.
|
2009-03-03 21:49:32 +01:00
|
|
|
|
2009-03-03 22:35:32 +01:00
|
|
|
If you want to know whether your code is vulnerable to this
|
|
|
|
|
issue, simply search for the substrings `PS_FontInfo' and
|
|
|
|
|
`PS_Font_Info' in your source code. If none is found, your code
|
|
|
|
|
is safe and is not affected.
|
2009-03-03 21:49:32 +01:00
|
|
|
|
|
|
|
|
The FreeType team apologizes for the problem.
|
|
|
|
|
|
2009-01-22 04:50:37 +01:00
|
|
|
- The POSIX support of MacOS resource-fork fonts (Suitcase fonts
|
|
|
|
|
and LaserWriter Type1 PostScript fonts) was broken in 2.3.8. If
|
|
|
|
|
FreeType2 is built without Carbon framework, these fonts are not
|
2009-01-22 06:53:35 +01:00
|
|
|
handled correctly. Version 2.3.7 didn't have this bug.
|
|
|
|
|
|
2009-02-24 22:34:51 +01:00
|
|
|
- `FT_Get_Advance' (and `FT_Get_Advances') returned bad values for
|
|
|
|
|
almost all font formats except TrueType fonts.
|
|
|
|
|
|
2009-03-04 00:34:49 +01:00
|
|
|
- Fix a bug in the SFNT kerning table loader/parser which could
|
|
|
|
|
crash the engine if certain malformed tables were encountered.
|
2009-01-18 07:42:59 +01:00
|
|
|
|
2009-03-09 19:06:28 +01:00
|
|
|
- Composite SFNT bitmaps are now handled correctly.
|
2009-01-18 07:42:59 +01:00
|
|
|
|
|
|
|
|
|
2009-03-11 22:29:54 +01:00
|
|
|
II. IMPORTANT CHANGES
|
|
|
|
|
|
|
|
|
|
- The new functions `FT_Get_CID_Is_Internally_CID_keyed' and
|
|
|
|
|
`FT_Get_CID_From_Glyph_Index' can be used to access CID-keyed
|
|
|
|
|
CFF fonts via CID values. This code has been contributed by
|
|
|
|
|
Michael Toftdal.

III. MISCELLANEOUS
|
2009-01-18 07:42:59 +01:00
|
|
|
|
|
|
|
|
- `FT_Outline_Get_InsideBorder' returns FT_STROKER_BORDER_RIGHT
|
|
|
|
|
for empty outlines. This was incorrectly documented.
|
|
|
|
|
|
2009-03-11 08:10:26 +01:00
|
|
|
- The `ftview' demo program now supports UTF-8 encoded strings.

CHANGES BETWEEN 2.3.8 and 2.3.7
|
|
|
|
|
|
|
|
|
|
I. IMPORTANT BUG FIXES
|
|
|
|
|
|
2008-09-20 14:20:21 +02:00
|
|
|
- CID-keyed fonts in an SFNT wrapper were not handled correctly.
|
|
|
|
|
|
2008-09-20 18:12:05 +02:00
|
|
|
- The smooth renderer produced truncated images (on the right) for
|
|
|
|
|
outline parts with negative horizontal values. Most fonts don't
|
|
|
|
|
contain outlines left to the y coordinate axis, but the effect
|
|
|
|
|
was very noticeable for outlines processed with FT_Glyph_Stroke,
|
|
|
|
|
using thick strokes.
|
|
|
|
|
|
2008-12-11 09:55:48 +01:00
|
|
|
- `FT_Get_TrueType_Engine_Type' returned a wrong value if both
|
|
|
|
|
configuration macros TT_CONFIG_OPTION_BYTECODE_INTERPRETER and
|
|
|
|
|
TT_CONFIG_OPTION_UNPATENTED_HINTING were defined.
|
2008-11-05 15:34:29 +01:00
|
|
|
|
2008-12-26 00:52:00 +01:00
|
|
|
- The `face_index' field in the `FT_Face' structure wasn't
|
|
|
|
|
initialized properly after calling FT_Open_Face and friends with
|
|
|
|
|
a positive face index for CFFs, WinFNTs, and, most importantly,
|
|
|
|
|
for TrueType Collections (TTCs).

|
|
in an SFNT wrapper has been added -- such fonts are used on the
|
|
|
|
|
Mac. The core SFNT tables `TYP1' and `CID ' are passed to the
|
|
|
|
|
PS Type 1 and CID-keyed PS font drivers; other tables (`ALMX',
|
|
|
|
|
`BBOX', etc.) are not supported yet.

|
|
|
- A new interface to extract advance values of glyphs without
|
|
|
|
|
loading their outlines has been added. The functions are called
|
|
|
|
|
`FT_Get_Advance' and `FT_Get_Advances'; they are defined in file
|
|
|
|
|
`ftadvanc.h' (to be accessed as FT_ADVANCES_H).
|
|
|
|
|
|
2008-12-18 07:32:10 +01:00
|
|
|
- A new function `FT_Get_FSType_Flags' (in FT_FREETYPE_H) has been
|
|
|
|
|
contributed by David Bevan to access the embedding and
|
|
|
|
|
subsetting restriction information of fonts.

III. MISCELLANEOUS
|
|
|
|
|
|
|
|
|
|
- FT_MulFix is now an inlined function; by default, assembler code
|
|
|
|
|
is provided for x86 and ARM. See FT_CONFIG_OPTION_INLINE_MULFIX
|
|
|
|
|
and FT_CONFIG_OPTION_NO_ASSEMBLER (in ftoption.h) for more.
|
|
|
|
|
|
2008-12-11 09:55:48 +01:00
|
|
|
- The handling of `tricky' fonts (this is, fonts which don't work
|
|
|
|
|
with the autohinter, needing the font format's hinting engine)
|
|
|
|
|
has been generalized and changed slightly:
|
|
|
|
|
|
|
|
|
|
. A new face flag FT_FACE_FLAG_TRICKY indicates that the font
|
|
|
|
|
format's hinting engine is necessary for correct rendering.
|
|
|
|
|
The macro FT_IS_TRICKY can be used to check this flag.
|
|
|
|
|
|
|
|
|
|
. FT_LOAD_NO_HINTING is now ignored for tricky fonts. To really
|
|
|
|
|
force raw loading of such fonts (without hinting), both
|
|
|
|
|
FT_LOAD_NO_HINTING and FT_LOAD_NO_AUTOHINT must be used --
|
|
|
|
|
this is something which you probably never want to do.
|
|
|
|
|
|
|
|
|
|
. Tricky TrueType fonts always use the bytecode interpreter,
|
|
|
|
|
either the patented or unpatented version.
|
|
|
|
|
|
2008-12-17 11:50:31 +01:00
|
|
|
- The function `FT_GlyphSlot_Own_Bitmap' has been moved from
|
|
|
|
|
FT_SYNTHESIS_H to FT_BITMAP_H; it is now part of the `official'
|
|
|
|
|
API. (The functions in FT_SYNTHESIS_H are still subject to
|
|
|
|
|
change, however.)
|
|
|
|
|
|
2009-01-07 09:27:37 +01:00
|
|
|
- In the `ftdiff' demo program you can now toggle the use of
|
|
|
|
|
FT_LOAD_IGNORE_GLOBAL_ADVANCE_WIDTH with key `a'.

CHANGES BETWEEN 2.3.7 and 2.3.6
|
|
|
|
|
|
|
|
|
|
I. IMPORTANT BUG FIXES
|
|
|
|
|
|
|
|
|
|
- If the library was compiled on an i386 platform using gcc, and
|
|
|
|
|
compiler option -O3 was given, `FT_MulFix' sometimes returned
|
|
|
|
|
incorrect results which could have caused problems with
|
|
|
|
|
`FT_Request_Metrics' and `FT_Select_Metrics', returning an
|
|
|
|
|
incorrect descender size.
|
|
|
|
|
|
2008-06-19 18:23:43 +02:00
|
|
|
- Pure CFFs without subfonts were scaled incorrectly if the font
|
|
|
|
|
matrix was non-standard. This bug has been introduced in
|
|
|
|
|
version 2.3.6.
|
|
|
|
|
|
2008-06-18 08:16:39 +02:00
|
|
|
- The `style_name' field in the `FT_FaceRec' structure often
|
|
|
|
|
contained a wrong value for Type 1 fonts. This misbehaviour
|
|
|
|
|
has been introduced in version 2.3.6 while trying to fix
|
|
|
|
|
another problem. [Note, however, that this value is
|
|
|
|
|
informative only since the used algorithm to extract it is
|
|
|
|
|
very simplistic.]

II. IMPORTANT CHANGES
|
|
|
|
|
|
|
|
|
|
- Two new macros, FT_OUTLINE_SMART_DROPOUTS and
|
|
|
|
|
FT_OUTLINE_EXCLUDE_STUBS, have been introduced. Together with
|
2008-06-25 22:58:33 +02:00
|
|
|
FT_OUTLINE_IGNORE_DROPOUTS (which was ignored previously) it is
|
2008-06-23 00:41:24 +02:00
|
|
|
now possible to control the dropout mode of the `raster' module
|
|
|
|
|
(for B&W rasterization), using the `flags' field in the
|
|
|
|
|
`FT_Outline' structure.
|
|
|
|
|
|
|
|
|
|
- The TrueType bytecode interpreter now passes the dropout mode to
|
|
|
|
|
the B&W rasterizer. This greatly increases the output for small
|
2008-06-29 09:43:41 +02:00
|
|
|
ppem values of many fonts like `pala.ttf'.

|
|
|
- Microsoft Unicode cmaps in TrueType fonts are now always
|
|
|
|
|
preferred over Apple cmaps. This is not a bug per se, but there
|
|
|
|
|
exist some buggy fonts created for MS which have broken Apple
|
|
|
|
|
cmaps. This affects only the automatic selection of FreeType;
|
|
|
|
|
it's always possible to manually select an Apple Unicode cmap if
|
|
|
|
|
desired.
|
|
|
|
|
|
2008-06-09 22:49:29 +02:00
|
|
|
- Many bug fixes to the TrueType bytecode interpreter.
|
|
|
|
|
|
2008-02-29 08:23:02 +01:00

|
|
|
|
2008-05-15 01:05:38 +02:00
|
|
|
- CID-keyed CFFs with subfonts which are scaled in a non-standard
|
|
|
|
|
way are now handled correctly.
|
|
|
|
|
|
2008-05-13 14:10:04 +02:00
|
|
|
- A call to FT_Open_Face with `face_index' < 0 crashed FreeType if
|
|
|
|
|
the font was a Windows (bitmap) FNT/FON.

2007-08-08 08:38:06 +02:00
|
|
|
- George Williams contributed code to validate the new `MATH'

|
|
2007-05-19 09:24:55 +02:00
|
|
|
I. IMPORTANT BUG FIXES
|
|
|
|
|
|
|
|
|
|
- Some subglyphs in TrueType fonts were handled incorrectly due to
|
|
|
|
|
a missing graphics state reinitialization.
|
|
|
|
|
|
2007-05-25 09:11:12 +02:00
|
|
|
- Large .Z files (as distributed with some X11 packages) weren't
|
|
|
|
|
handled correctly, making FreeType increase the heap stack in an
|
|
|
|
|
endless loop.
|
|
|
|
|
|
2007-07-02 17:14:50 +02:00
|

|
|
|
|
|
|
2007-05-25 09:11:12 +02:00
|
|
|
- The two new cache functions `FTC_ImageCache_LookupScaler' and
|
|
|
|
|
`FTC_SBit_Cache_LookupScaler' have been added to allow lookup of
|
|
|
|
|
glyphs using an `FTC_Scaler' object; this makes it possible to
|
2007-05-29 09:00:23 +02:00
|
|
|
use fractional pixel sizes in the cache. The demo programs have
|
|
|
|
|

|
- A new API `FT_Get_CMap_Format' has been added to get the cmap
|
2007-05-19 16:10:06 +02:00
|
|
|
format of a TrueType font. This is useful in handling PDF

|
|
- The auto-hinter now produces better output by default for
|
|
|
|
|
non-Latin scripts like Indic. This was done by using the CJK
|
|
|
|
|
hinting module as the default instead of the Latin one. Thanks

to Rahul Bhalerao for this suggestion.

out whether a given TrueType font uses patented bytecode
|
2007-06-16 11:32:31 +02:00

I. IMPORTANT BUG FIXES
|
|
|
|
|
|
|
|
|
|
- A serious bug in the handling of bitmap fonts (and bitmap
|
|
|
|
|
strikes of outline fonts) has been introduced in 2.3.3.

|
|
|
|
|
|
|
|
I. IMPORTANT BUG FIXES
|
|
|
|
|
|
|
|
|
|
- Remove a serious regression in the TrueType bytecode interpreter
|
2007-03-28 23:17:11 +02:00
|
|
|
that was introduced in version 2.3.2. Note that this does not
|
2007-05-19 16:10:06 +02:00
|
|
|
disable the improvements introduced to the interpreter in
|
|
|
|
|
version 2.3.2, only some ill cases that occurred with certain
|
|
|
|
|
fonts (though a few popular ones).
|
2007-03-28 23:17:11 +02:00
|
|
|
|
|
|
|
|
- The auto-hinter now ignores single-point contours for computing
|
|
|
|
|
blue zones. This bug created `wavy' baselines when rendering
|
|
|
|
|
text with various fonts that use these contours to model
|
|
|
|
|
mark-attach points (these are points that are never rasterized
|
|
|
|
|
and are placed outside of the glyph's real outline).
|
|
|
|
|
|
2007-05-19 16:10:06 +02:00
|
|
|
- The `rsb_delta' and `lsb_delta' glyph slot fields are now set to
|
2007-05-29 09:00:23 +02:00
|
|
|
zero for mono-spaced fonts. Otherwise code that uses them would
|
2007-03-26 15:37:17 +02:00
|
|
|
essentially ruin the fixed-advance property.
|
|
|
|
|
|
2007-05-19 16:10:06 +02:00
|
|
|
- Fix CVE-2007-1351 which can cause an integer overflow while
|
|
|
|
|
parsing BDF fonts, leading to a potentially exploitable heap
|
2007-04-05 04:28:23 +02:00
|
|
|
overflow condition.

II. MISCELLANEOUS
|
|
|
|
|
|
|
|
|
|
- Fixed compilation issues on some 64-bit platforms (see ChangeLog
|
|
|
|
|
for details).
|
|
|
|
|
|
|
|
|
|
- A new demo program `ftdiff' has been added to compare TrueType
|
|
|
|
|
hinting, FreeType's auto hinting, and rendering without hinting
|
|
|
|
|
in three columns.

|
|
|
I. IMPORTANT BUG FIXES
|
|
|
|
|
|
2007-03-09 08:59:35 +01:00
|
|
|
- FreeType returned incorrect kerning information from TrueType
|
|
|
|
|
fonts when the bytecode interpreter was enabled. This happened
|
|
|
|
|
due to a typo introduced in version 2.3.0.
|
2007-03-08 17:43:50 +01:00
|
|
|
|
2007-03-09 08:59:35 +01:00
|
|
|
- Negative kerning values from PFM files are now reported
|
|
|
|
|
correctly (they were read as 16-bit unsigned values from the
|
|
|
|
|
file).
|
2007-03-08 17:43:50 +01:00
|
|
|
|
2007-03-09 08:59:35 +01:00
|
|
|
- Fixed a small memory leak when `FT_Init_FreeType' failed for
|
|
|
|
|
some reason.
|
2007-03-08 17:43:50 +01:00
|
|
|
|
2007-03-09 08:59:35 +01:00
|
|
|
- The Postscript hinter placed and sized very thin and ghost stems
|
|
|
|
|
incorrectly.
|
|
|
|
|
|
|
|
|
|
- The TrueType bytecode interpreter has been fixed to get rid of
|
|
|
|
|
most of the rare differences seen in comparison to the Windows
|
|
|
|
|
font loader.

II. IMPORTANT CHANGES
|
|
|
|
|
|
2007-03-09 08:59:35 +01:00
|
|
|
- The auto-hinter now better deals with serifs and corner cases
|
|
|
|
|
(e.g., glyph '9' in Arial at 9pt, 96dpi). It also improves
|
|
|
|
|
spacing adjustments and doesn't change widths for non-spacing
|
|
|
|
|
glyphs.
|
|
|
|
|
|
|
|
|
|
- Many Mac-specific functions are deprecated (but still
|
|
|
|
|
available); modern replacements have been provided for them.

|
|
|
|
|

|
|
|

metrics due to a bug in the handling of the SHZ instruction.
|
|
|
|
|
|
2007-01-25 12:50:00 +01:00

CHANGES BETWEEN 2.2.1 and 2.2.2
I. IMPORTANT BUG FIXES
- Various integer overflows have been fixed.
- PFB fonts with MacOS resource fork weren't handled correctly on
non-MacOS platforms.
- The PCF font loarder has been seriously hardened against malformed
font files.
II. IMPORTANT CHANGES
- the unpatented hinter is now part of the default build of the
library, and we added code to automatically support "tricky"
fonts that need it.
what this means is that FreeType should "just work" with certain
Asian fonts, like MingLiu, which cannot properly load without a
bytecode interpreter, but fortunately do not use any of the
patented bytecode opcodes.
Note that the API didn't change, so you can still force
unpatented hinting with a special parameter to FT_Open_Face
as well.
if you're an embedded systems developer, you might want to
*disable* the feature to save code space by undefining
TT_CONFIG_OPTION_UNPATENTED_HINTING in ftoption.h.
- LCD-optimized rendering is now disabled in all default builds
of the library, mainly due to patent reasons. For more information
see:
http://lists.gnu.org/archive/html/freetype/2006-09/msg00064.html
a new configuration macro FT_CONFIG_OPTION_SUBPIXEL_RENDERING has
been introduced in ftoption.h; manually define it in this file
if you want to re-enable the feature.
the change only affects the implementation, not the FreeType API.
This means that clients don't need to be modified, because the
library still generates LCD decimated bitmaps, but with the added
constraint that R=G=B on each triplet.
- Some computation bugs in the TrueType bytecode interpreter were found,
which allow us to get rid of very subtle and rare differences we had
with the Windows renderer.
III. MISCELLANEOUS
- TrueType glyph loading is now about 25% faster.
- the anti-aliased rasterizer has been optimized and is now 15% to 25%
percent faster than the previous one, depending on content
- the Type 1 loader has been improved; as an example, it now skips
over top-level dictionaries properly

|
|
|
|
encode their names in UTF-16 (the specification was vague, and
|
|
|
|
|
the code incorrectly assumed UCS-4).

the change only affects the implementation, not the FreeType API.
This means that clients don't need to be modified, because the
library still generates LCD decimated bitmaps, but with the added
constraint that R=G=B on each triplet.
- Some computation bugs in the TrueType bytecode interpreter were found,
which allow us to get rid of very subtle and rare differences we had
with the Windows renderer.
III. MISCELLANEOUS
- TrueType glyph loading is now about 25% faster.
- the anti-aliased rasterizer has been optimized and is now 15% to 25%
percent faster than the previous one, depending on content
- the Type 1 loader has been improved; as an example, it now skips
over top-level dictionaries properly

CHANGES BETWEEN 2.2.1 and 2.2.2
I. IMPORTANT BUG FIXES
- Various integer overflows have been fixed.
- PFB fonts with MacOS resource fork weren't handled correctly on
non-MacOS platforms.
- The PCF font loarder has been seriously hardened against malformed
font files.
II. IMPORTANT CHANGES
- the unpatented hinter is now part of the default build of the
library, and we added code to automatically support "tricky"
fonts that need it.
what this means is that FreeType should "just work" with certain
Asian fonts, like MingLiu, which cannot properly load without a
bytecode interpreter, but fortunately do not use any of the
patented bytecode opcodes.
Note that the API didn't change, so you can still force
unpatented hinting with a special parameter to FT_Open_Face
as well.
if you're an embedded systems developer, you might want to
*disable* the feature to save code space by undefining
TT_CONFIG_OPTION_UNPATENTED_HINTING in ftoption.h.
- LCD-optimized rendering is now disabled in all default builds
of the library, mainly due to patent reasons. For more information
see:
http://lists.gnu.org/archive/html/freetype/2006-09/msg00064.html
a new configuration macro FT_CONFIG_OPTION_SUBPIXEL_RENDERING has
been introduced in ftoption.h; manually define it in this file
if you want to re-enable the feature.
the change only affects the implementation, not the FreeType API.
This means that clients don't need to be modified, because the
library still generates LCD decimated bitmaps, but with the added

|
|
|
|
|
|
2005-09-09 20:00:06 +02:00
|
|
|
- The FT_HAS_KERNING macro always returned 0.
|
|
|
|
|
|
2005-12-23 16:10:54 +01:00
|
|
|
- CFF OpenType fonts didn't return correct vertical metrics for

2005-11-17 09:12:00 +01:00
|
|
|
glyphs with outlines.
|
|
|
|
|
|
2005-11-18 22:10:59 +01:00

II. IMPORTANT CHANGES
|
|
|
|
|
|
2006-02-28 22:49:54 +01:00
|
|
|
- Version 2.2 no longer exposes its internals, this is, the header
|
|
|
|
|
files located in the `include/freetype/internal' directory of
|
|
|
|
|
the source package are not copied anymore by the `make install'
|
|
|
|
|
command. Consequently, a number of rogue clients which directly
|
|
|
|
|
access FreeType's internal functions and structures won't
|
|
|
|
|
compile without modification.
|
2006-03-24 12:54:53 +01:00
|
|
|
|
2006-02-28 22:49:54 +01:00
|
|
|
We provide patches for most of those rogue clients. See the
|
|
|
|
|
following page for more information:

|
|
|
|
|
|
|
|
Note that, as a convenience to our Unix desktop users, version
|
|
|
|
|
2.2 is *binary* compatible with FreeType 2.1.7, which means that
|
|
|
|
|
installing this release on an existing distribution shall not
|
|
|
|
|
break any working desktop.

Implement new, simplified module selection. With GNU make it is now
sufficient to modify a single file, `modules.cfg', to control the
inclusion of modules and base extension files.
This change also fixes the creation of ftmodule.h; it now depends on
`modules.cfg' and thus is rebuilt only if necessary.
Finally, a version of `ftoption.h' in OBJ_DIR is preferred over the
default location.
* modules.cfg: New file.
* builds/freetype.mk: Don't include `modules.mk'.
Include all `rules.mk' files as specified in `modules.cfg'.
(FTOPTION_FLAG, FTOPTION_H): New variables.
(FT_CFLAGS): Add macro definition for FT_CONFIG_MODULES_H.
Add FTOPTION_FLAG.
($(FT_INIT_OBJ)): Don't use FT_MODULE_LIST.
(CONFIG_H): Add FTMODULE_H and FTOPTION_H.
(INCLUDES): Add DEVEL_DIR.
(INCLUDE_FLAGS, FTSYS_SRC, FTSYS_OBJ, FTDEBUG_SRC, FTDEBUG_OBJ,
OBJ_M, OBJ_S): Use `:=', not `='.
(remove_ftmodule_h): New phony target to delete `ftmodule.h'.
(distclean): Add remove_ftmodule_h.
* builds/modules.mk: (MODULE_LIST): Removed.
(make_module_list, clean_module_list): Replace targets
with...
(FTMODULE_H_INIT, FTMODULE_H_CREATE, FTMODULE_H_DONE): New
variables. Reason for the change is that it is not possible to have
a phony prerequisite which is run only if the target file must be
rebuilt (phony prerequisites act like subroutines and are *always*
executed). We only want to rebuild `ftmodule.h' if `module.cfg' is
changed.
Update all callers.
($FTMODULE_H)): Rule to create `ftmodule.h', depending on
`modules.cfg'.
* builds/toplevel.mk: Rewrite and simplify module handling.
(MODULES_CFG, FTMODULE_H): New variables.
Include MODULES_CFG.
(MODULES): New variable to include all `module.mk' and `rules.mk'
files. We no longer use make's `wildcard' function for this.
* Makefile (USE_MODULES): Remove. Update all users.
(OBJ_DIR): Define it here.
* src/*/module.mk: Change
make_module_list: foo
foo: ...
to
FTMODULE_H_COMMANDS += FOO
define FOO
...
endef
in all files. `FTMODULE_H_COMMANDS' is used in `FTMODULE_H_CREATE'.
* src/base/rules.mk (BASE_EXT_SRC): Use BASE_EXTENSIONS.
* builds/unix/detect.mk (setup): Always execute `configure' script.
(have_mk): Rename to...
(have_Makefile): This.
Don't use `strip' function.
* builds/unix/unix.mk: Include `install.mk' only if BUILD_PROJECT is
defined.
(have_mk): Don't use `strip' function.
Test for unix-def.mk in OBJ_DIR, not BUILD_DIR (and invert the test
accordingly).
* builds/unix/install.mk (install, uninstall): Handle `ftmodule.h'.
* builds/os2/os2-dev.mk, builds/unix/unix-dev.mk,
builds/win32/w32-bccd.mk, builds/win32/w32-dev.mk: Don't define
BUILD_DIR but DEVEL_DIR for development header files.
* builds/ansi/ansi-def.mk (TOP_DIR, OBJ_DIR),
builds/beos/beos-def.mk (TOP_DIR, OBJ_DIR), builds/unix/unix-def.in
(TOP_DIR, OBJ_DIR): Removed. Defined elsewhere.
* builds/dos/dos-def.mk (OBJ_DIR), builds/os2/os2-def.mk (OBJ_DIR),
builds/win32/win32-def.mk (OBJ_DIR): Removed. Defined elsewhere.
* builds/unix/unixddef.mk: Don't define BUILD_DIR but DEVEL_DIR for
development header files.
Don't define PLATFORM.
* configure: Copy `modules.cfg' to builddir if builddir != srcdir.
Update snippet taken from autoconf's m4sh.m4 to current CVS version.
Be more verbose.
* include/freetype/config/ftmodule.h: Add comments -- this file is
no longer used if FreeType is built with GNU make.
* docs/CHANGES, docs/CUSTOMIZE, docs/INSTALL, docs/INSTALL.ANY,
docs/INSTALL.GNU, docs/INSTALL.UNX: Document new build mechanism.
Other minor updates.
* modules.txt: Removed. Contents included in `modules.cfg'.
* include/freetype/internal/ftmemory.h (FT_QAlloc_Debug,
FT_Free_Debug) [FT_STRICT_ALIASING]: Fix typos.
* src/base/ftdbgmem.c (FT_Alloc_Debug, FT_Realloc_Debug,
FT_QAlloc_Debug, FT_QRealloc_Debug, FT_Free_Debug)
[FT_STRICT_ALIASING]: Implement.
2006-01-31 21:17:42 +01:00
|
|
|
- FreeType's build mechanism has been redesigned. With GNU make
|
|
|
|
|
it is now sufficient in most cases to edit two files:
|
|
|
|
|
`modules.cfg', to select the library components, and the
|
|
|
|
|
configuration file `include/freetype/config/ftoption.h' (which
|
|
|
|
|
can be copied to the objects directory). Removing unused module
|
|
|
|
|
directories to prevent its compilation and editing
|
|
|
|
|
`include/freetype/config/ftmodule.h' is no longer necessary.
|
|
|
|
|
|
2005-12-23 16:10:54 +01:00
|
|
|
- The LIGHT hinting algorithm produces more pleasant results.
|
|
|
|
|
Also, using the FT_LOAD_TARGET_LIGHT flags within FT_Load_Glyph
|
2006-04-01 20:49:07 +02:00
|
|
|
always forces auto-hinting, as a special exception. This allows
|
|
|
|
|
you to experiment with it even if you have enabled the TrueType
|
2006-04-01 18:22:06 +02:00
|
|
|
bytecode interpreter in your build.
|
|
|
|
|
|
|
|
|
|
- The auto hinter now employs a new algorithm for CJK fonts, based
|
|
|
|
|
on Akito Hirai's patch. Note that this only works for fonts
|
|
|
|
|
with a Unicode charmap at the moment.

units.
. As we use the glyph's cbox to calculate the top bearing now
there iss no need to adjust `top'.
* src/otvalid/otvcommn.h (OTV_OPTIONAL_TABLE): Use FT_UShort to be
in sync with OTV_OPTIONAL_OFFSET. Reported by YAMATO Masatake.
* docs/release: Update.

|
|
|
- On MacOS, new APIs have been added as replacements for legacy
|
|
|
|
|
APIs: `FT_New_Face_From_FSRef' for `FT_New_Face_From_FSSpec',
|
|
|
|
|
and `FT_GetFile_From_Mac_ATS_Name' for
|
|
|
|
|
`FT_GetFile_From_Mac_Name'. Legacy APIs are still available, if
|
|
|
|
|
FreeType is built without disabling them.
|
|
|
|
|
|
2006-03-24 12:54:53 +01:00
|
|
|
- A new API `FT_Select_Size' has been added to select a bitmap
|
|
|
|
|
strike by its index. Code using other functions to select
|
|
|
|
|
bitmap strikes should be updated to use this function.
|
|
|
|
|
|
|
|
|
|
- A new API `FT_Get_SubGlyph_Info' has been added to retrieve
|
2006-04-01 20:49:07 +02:00
|
|
|
subglyph data. This can be used by rogue clients which used to
|
2006-04-01 18:22:06 +02:00
|
|
|
access the internal headers to get the corresponding data.
|
2006-01-14 06:09:30 +01:00
|
|
|
|
2006-03-24 12:54:53 +01:00
|
|
|
- In 2.1.10, the behaviour of `FT_Set_Pixel_Sizes' was changed for
|
2006-02-28 22:49:54 +01:00
|
|
|
BDF/PCF fonts, and only for them. This causes inconsistency.
|
|
|
|
|
In this release, we undo the change. The intent of the change
|
2006-01-14 06:09:30 +01:00
|
|
|
in 2.1.10 is to allow size selection through real dimensions,
|
|
|
|
|
which can now be done through `FT_Request_Size'.
|
|
|
|
|
|
2006-02-28 22:49:54 +01:00
|
|
|
- Some security issues were discovered and fixed in the CFF and
|
|
|
|
|
Type 1 loader, causing crashes of FreeType by malformed font
|
|
|
|
|
files.

III. MISCELLANEOUS
|
|
|
|
|
|
2005-12-23 16:10:54 +01:00
|
|
|
- The documentation for FT_LOAD_TARGET_XXX and FT_RENDER_MODE_XXX
|
|
|
|
|
values now better reflects its usage and differences: One set is
|
2006-03-20 12:48:13 +01:00
|
|
|
used to specify the hinting algorithm, the other to specify the
|
|
|
|
|
pixel rendering mode.
|
2006-02-28 22:49:54 +01:00
|
|
|
|
2007-01-09 11:37:36 +01:00
|
|
|
- `FT_New_Face' and `FT_New_Face_From_FSSpec' in ftmac.c have been
|
2005-12-23 16:10:54 +01:00
|
|
|
changed to count supported scalable faces (sfnt, LWFN) only, and
|
2006-03-24 12:54:53 +01:00
|
|
|
to return the number of available faces via face->num_faces.
|
2005-12-23 16:10:54 +01:00
|
|
|
Unsupported bitmap faces (fbit, NFNT) are ignored.
|
2005-12-23 13:22:46 +01:00
|
|
|
|
2006-01-11 11:57:42 +01:00
|
|
|
- builds/unix/configure has been improved for MacOS X. It now
|
|
|
|
|
automatically checks available functions in Carbon library, and
|
|
|
|
|
prepare to use newest functions by default. Options to specify
|
|
|
|
|
the dependencies of each Carbon APIs (FSSpec, FSRef, old/new
|
|
|
|
|
QuickDraw, ATS) are available too. By manual disabling of all
|
|
|
|
|
QuickDraw functionality, FreeType can be built without
|
|
|
|
|
`deprecated function' warnings on MacOS 10.4.x, but
|
|
|
|
|
FT_GetFile_Mac_Name in ftmac.c then is changed to a dummy
|
|
|
|
|
function, and returns an `unimplemented' error. For details see
|
|
|
|
|
builds/mac/README.
|
2006-01-11 10:28:38 +01:00
|
|
|
|
2006-02-28 22:49:54 +01:00
|
|
|
- SFNT cmap handling has been improved, mainly to run much faster
|
2006-02-28 10:26:58 +01:00
|
|
|
with CJK fonts.
|
2005-10-05 17:18:29 +02:00
|
|
|
|
2006-02-26 18:50:59 +01:00
|
|
|
- A new function `FT_Get_TrueType_Engine_Type (declared in
|
|
|
|
|
`FT_MODULE_H') is provided to determine the status of the
|
|
|
|
|
TrueType bytecode interpreter compiled into the library
|
|
|
|
|
(patented, unpatented, unimplemented).
|
2006-01-08 23:34:01 +01:00
|
|
|
|
2006-01-15 16:01:45 +01:00
|
|
|
- Vertical metrics of glyphs are synthesized if the font does not
|
|
|
|
|
provide such information. You can tell whether the metrics are
|
|
|
|
|
synthesized or not by checking the FT_FACE_FLAG_VERTICAL flag of
|
|
|
|
|
the face.
|
|
|
|
|
|
2005-06-23 22:31:48 +02:00
|
|
|
- The demo programs `ftview' and `ftstring' have been rewritten
|
2006-05-06 18:44:58 +02:00
|
|
|
for better readability. `ftview' has a new switch `-p' to test
|
|
|
|
|
FT_New_Memory_Face (instead of FT_New_Face).
|
2005-06-22 05:56:14 +02:00
|
|
|
|
2005-08-22 09:11:31 +02:00
|
|
|
- FreeType now honours bit 1 in the `head' table of TrueType fonts
|
2005-12-23 16:10:54 +01:00
|
|
|
(meaning `left sidebearing point at x=0'). This helps with some
|
|
|
|
|
buggy fonts.
|
2005-08-22 09:11:31 +02:00
|
|
|
|
2005-09-23 09:40:28 +02:00
|
|
|
- Rudimentary support for Adobe's new `SING Glyphlet' format. See

CHANGES BETWEEN 2.1.10 and 2.1.9
|
2004-08-02 07:38:33 +02:00
|
|
|
|
|
|
|
|
I. IMPORTANT BUG FIXES
|
|
|
|
|
|
|
|
|
|
- The size comparison for BDF and PCF files could fail sometimes.
|
|
|
|
|
|
|
|
|
|
- Some CFF files were still not loaded correctly. Patch from
|
|
|
|
|
Derek Noonburg.
|
|
|
|
|
|
|
|
|
|
- The stroker still had some serious bugs.
|
|
|
|
|
|
2004-10-09 09:07:43 +02:00
|
|
|
- Boris Letocha fixed a bug in the TrueType interpreter: The
|
|
|
|
|
NPUSHW instruction wasn't skipped correctly in IF clauses. Some
|
|
|
|
|
fonts like `Helvetica 75 Bold' failed.
|
|
|
|
|
|
2004-11-19 15:12:48 +01:00
|
|
|
- Another serious bug in handling TrueType hints caused many
|
|
|
|
|
distortions. It has been introduced in version 2.1.8, and it is
|
|
|
|
|
highly recommended to upgrade.
|
2004-11-19 11:35:52 +01:00
|
|
|
|
2005-02-10 09:18:27 +01:00
|
|
|
- FreeType didn't properly parse empty Type 1 glyphs.
|
2005-12-23 14:32:06 +01:00
|
|
|
|
2005-03-16 02:49:54 +01:00
|
|
|
- An unbound dynamic buffer growth was fixed in the PFR loader.
|
2005-12-23 14:32:06 +01:00
|
|
|
|
2005-03-16 02:49:54 +01:00
|
|
|
- Several bugs have been fixed in the cache sub-system.
|
2005-03-16 00:31:48 +01:00
|
|
|
|
2005-03-16 02:49:54 +01:00
|
|
|
- FreeType behaved incorrectly when resizing two distinct but very
|
|
|
|
|
close character pixel sizes through `FT_Set_Char_Size' (Savannah
|
|
|
|
|
bug #12263).
|
2005-12-23 14:32:06 +01:00
|
|
|
|
2005-03-16 02:49:54 +01:00
|
|
|
- The auto-hinter didn't work properly for fonts without a Unicode
|
|
|
|
|
charmap -- it even refused to load the glyphs.
|
2005-02-10 09:18:27 +01:00

II. IMPORTANT CHANGES
|
|
|
|
|
|
2005-03-16 02:49:54 +01:00
|
|
|
- Many fixes have been applied to drastically reduce the amount of
|
|
|
|
|
heap memory used by FreeType, especially when using
|
|
|
|
|
memory-mapped font files (which is the default on Unix systems
|
|
|
|
|
which support them).
|
2005-03-16 00:31:48 +01:00
|
|
|
|
2005-03-23 17:45:24 +01:00
|
|
|
- The auto-hinter has been replaced with a new module, called the
|
|
|
|
|
`auto-fitter'. It consumes less memory than its predecessor,
|
|
|
|
|
and it is prepared to support non-latin scripts better in next
|
|
|
|
|
releases.
|
2005-03-16 00:31:48 +01:00
|
|
|
|
2004-08-02 07:38:33 +02:00
|
|
|
- George Williams contributed code to read kerning data from PFM
|
|
|
|
|
files.
|
|
|
|
|
|
|
|
|
|
- FreeType now uses the TT_NAME_ID_PREFERRED_FAMILY and
|
|
|
|
|
TT_NAME_ID_PREFERRED_SUBFAMILY strings (if available) for
|
|
|
|
|
setting family and style in SFNT fonts (patch from Kornfeld
|
|
|
|
|
Eliyahu Peter).
|
|
|
|
|
|
2004-08-11 07:25:37 +02:00
|
|
|
- A new API `FT_Sfnt_Table_Info' (in FT_TRUETYPE_TABLES_H) has
|
|
|
|
|
been added to retrieve name and size information of SFNT tables.
|
|
|
|
|
|
Adding OpenType validation module. The code is based on the
(unfinished) `otlayout' module but has been heavily modified to make
it much more compact.
* src/otvalid/*: New module.
* include/freetype/ftotval.h, src/base/ftotval.c,
include/freetype/internal/services/svotval.h: New files.

* include/freetype/ftchapters.h: Updated.
* src/base/Jamfile (Library), src/base/descrip.mms (OBJS),
src/base/rules.mk (BASE_EXT_SRC): Updated.
* docs/CHANGES: Updated.
2004-09-10 16:39:00 +02:00
|
|
|
- A new API `FT_OpenType_Validate' (in FT_OPENTYPE_VALIDATE_H) has
|
|
|
|
|
been added to validate OpenType tables (BASE, GDEF, GPOS, GSUB,
|
|
|
|
|
JSTF). After validation it is no longer necessary to check
|
2004-10-09 09:07:43 +02:00
|
|
|
for errors in those tables while accessing them.

|
Note that this module might be moved to another library in the
|
|
|
|
|
future to avoid a tight dependency between FreeType and the
|
|
|
|
|
OpenType specification.
|
|
|
|
|
|
2004-12-14 17:01:29 +01:00
|
|
|
- A new API in FT_BITMAP_H (`FT_Bitmap_New', `FT_Bitmap_Convert',
|
2005-05-25 07:51:01 +02:00
|
|
|
`FT_Bitmap_Copy', `FT_Bitmap_Embolden', `FT_Bitmap_Done') has
|
|
|
|
|
been added. Its use is to convert an FT_Bitmap structure in
|
|
|
|
|
1bpp, 2bpp, 4bpp, or 8bpp format into another 8bpp FT_Bitmap,
|
|
|
|
|
probably using a different pitch, and to further manipulate it.
|
|
|
|
|
|
|
|
|
|
- A new API `FT_Outline_Embolden' (in FT_OUTLINE_H) gives finer
|
2017-01-25 05:56:59 +01:00
|
|
|
control how outlines are emboldened.
|
2005-05-25 07:51:01 +02:00
|
|
|
|
|
|
|
|
- `FT_GlyphSlot_Embolden' (in FT_SYNTHESIS_H) now handles bitmaps
|
|
|
|
|
also (code contributed by Chia I Wu). Note that this function
|
|
|
|
|
is still experimental and may be replaced with a better API.
|
2004-12-14 17:01:29 +01:00
|
|
|
|
2005-04-03 22:11:42 +02:00
|
|
|
- The method how BDF and PCF bitmap fonts are accessed has been
|
|
|
|
|
refined. Formerly, FT_Set_Pixel_Sizes and FT_Set_Char_Size
|
|
|
|
|
were synonyms in FreeType's BDF and PCF interface. This has
|
|
|
|
|
changed now. FT_Set_Pixel_Sizes should be used to select the
|
|
|
|
|
actual font dimensions (the `strike', which is the sum of the
|
|
|
|
|
`FONT_ASCENT' and `FONT_DESCENT' properties), while
|
|
|
|
|
FT_Set_Char_Size selects the `nominal' size (the `PIXELSIZE'
|
|
|
|
|
property). In both functions, the width parameter is ignored.

|
|
III. MISCELLANEOUS
|
|
|
|
|
|
|
|
|
|
- The BDF driver no longer converts all returned bitmaps with a
|
|
|
|
|
depth of 2bpp or 4bpp to a depth of 8bpp. The documentation has
|
|
|
|
|
not mentioned this explicitly, but implementors might have
|
|
|
|
|
relied on this after looking into the source files.
|
|
|
|
|
|
2005-02-10 09:18:27 +01:00
|
|
|
- A new option `--ftversion' has been added to freetype-config to
|
|
|
|
|
return the FreeType version.
|
|
|
|
|
|
2005-03-23 17:45:24 +01:00
|
|
|
- The memory debugger has been updated to dump allocation
|
|
|
|
|
statistics on all allocation sources in the library. This is
|
|
|
|
|
useful to spot greedy allocations when loading and processing
|
|
|
|
|
fonts.
|
2005-03-16 00:31:48 +01:00
|
|
|
|
2005-03-23 17:45:24 +01:00
|
|
|
- We removed a huge array of constant pointers to constant strings
|
|
|
|
|
in the `psnames' module. The problem was that compilations in
|
|
|
|
|
PIC mode (i.e., when generating a Unix shared object/dll) put
|
|
|
|
|
the array into the non-shared writable section of the library
|
2005-03-16 00:31:48 +01:00
|
|
|
since absolute pointers are not relocatable by nature.
|
2005-12-23 14:32:06 +01:00
|
|
|
|
2005-03-23 17:45:24 +01:00
|
|
|
This reduces the memory consumption by approximately 16KByte per
|
|
|
|
|
process linked to FreeType. We now also store the array in a
|
|
|
|
|
compressed form (as a trie) which saves about 20KByte of code as
|
|
|
|
|
well.

|
|
|
I. IMPORTANT BUG FIXES
|
|
|
|
|
|
|
|
|
|
- The function `FT_Get_CharMap_Index' was only declared, without
|
|
|
|
|
any real code. For consistency, it has been renamed to
|
|
|
|
|
`FT_Get_Charmap_Index'. (This function is needed to implement
|
|
|
|
|
cmap caches.)
|
|
|
|
|
|
2004-06-05 00:30:10 +02:00
|
|
|
- `FT_Outline_Get_BBox' sometimes returned incorrect values for
|
2004-06-22 14:28:17 +02:00
|
|
|
conic outlines (e.g., for TrueType fonts).
|
2004-06-05 00:30:10 +02:00
|
|
|
|
|
|
|
|
- Handling of `bhed' table has been fixed.
|
2004-04-24 16:43:37 +02:00
|
|
|
|
2004-06-22 01:32:31 +02:00
|
|
|
- The TrueType driver with enabled byte code interpreter sometimes
|
|
|
|
|
returned artifacts due to incorrect rounding. This bug has been
|
|
|
|
|
introduced after version 2.1.4.
|
|
|
|
|
|
2004-06-22 14:28:17 +02:00
|
|
|
- The BDF driver dropped the last glyph in the font.
|
|
|
|
|
|
|
|
|
|
- The BDF driver now uses the DEFAULT_CHAR property (if available)
|
|
|
|
|
to select a glyph shape for the undefined glyph.
|
|
|
|
|
|
2004-07-17 18:45:21 +02:00
|
|
|
- The stroker failed for closed outlines and single points.
|
|
|
|

|
II. IMPORTANT CHANGES
|
|
|
|
|
|
|
|
|
|
- George Williams contributed code to handle Apple's font
|
|
|
|
|
distortion technology found in GX fonts (`avar', `cvar', `fvar',
|
|
|
|
|
and `gvar' tables; the Multiple Masters API has been slightly
|
2004-06-05 00:30:10 +02:00
|
|
|
extended to cope with the new functionality).
|
|
|
|
|
|
2004-06-12 15:21:20 +02:00
|
|
|
- The `FT_GlyphSlotRec' structure has been extended: The elements
|
2004-06-05 00:30:10 +02:00
|
|
|
`lsb_delta' and `rsb_delta' give the difference between hinted
|
|
|
|
|
and unhinted left and right side bearings if autohinting is
|
|
|
|
|
active. Using those values can improve the inter-letter spacing
|
2004-06-12 15:21:20 +02:00
|
|
|
considerably. See the documentation of `FT_GlyphSlotRec' and
|
2004-06-05 00:30:10 +02:00
|
|
|
the `ftstring' demo program how to use it.
|
2004-04-26 10:09:30 +02:00
|
|
|
|
2004-07-17 18:45:21 +02:00
|
|
|
- Loading TrueType and Type 1 fonts has been made much faster.
|
|
|
|
|
|
|
|
|
|
- The stroker is no longer experimental (but the cache subsystem
|
|
|
|
|
still is).

III. MISCELLANEOUS
|

|
|
|
|
|
|

|
|
|
I. IMPORTANT BUG FIXES
|
|
|
|
|
|
2003-11-25 10:30:57 +01:00
|
|
|
- The native TrueType hinter contained some bugs which prevented
|
|
|
|
|
some fonts to be rendered correctly, most notably Legendum.otf.
|
|
|
|
|
|
2004-04-16 11:56:30 +02:00
|
|
|
- The PostScript hinter now produces improved results.
|
2004-02-24 08:52:45 +01:00
|
|
|
|
2003-11-25 10:30:57 +01:00
|
|
|
- The linear advance width and height values were incorrectly
|
|
|
|
|
rounded, making them virtually unusable if not loaded with
|
|
|
|
|
FT_LOAD_LINEAR_DESIGN.
|
|
|
|
|
|
2003-12-26 08:26:08 +01:00
|
|
|
- Indexing CID-keyed CFF fonts is now working: The glyph index is
|
|
|
|
|
correctly treated as a CID, similar to FreeType's CID driver
|
2004-02-24 08:52:45 +01:00
|
|
|
module. Note that CID CMap support is still missing.
|
2003-12-12 16:38:39 +01:00
|
|
|
|
2017-04-17 05:41:26 +02:00
|
|
|
- The FT_FACE_FLAG_GLYPH_NAMES flag is now set correctly for all
|
2004-04-21 09:36:38 +02:00
|
|
|
font formats.
|
2003-12-17 22:57:56 +01:00
|
|
|
|
2003-12-26 08:26:08 +01:00
|
|
|
- Some subsetted Type 1 fonts weren't parsed correctly. This bug
|
2004-02-08 10:07:08 +01:00
|
|
|
has been introduced in 2.1.7. In summary, the Type 1 parser has
|
|
|
|
|
become more robust.
|
2003-12-23 00:01:20 +01:00
|
|
|
|
2004-04-21 09:36:38 +02:00
|
|
|
- Non-decimal numbers weren't parsed correctly in PS fonts.
|
|
|
|
|
|
2003-12-23 00:01:20 +01:00
|
|
|
- The WinFNT driver now correctly reports FT_ENCODING_NONE for all
|
2003-12-26 08:26:08 +01:00
|
|
|
but one encoding. Use the new FT_WinFNT_ID_XXX values together
|
2007-01-09 11:37:36 +01:00
|
|
|
with `FT_Get_WinFNT_Header' to get the WinFNT charset ID.
|
2003-12-23 00:01:20 +01:00
|
|
|
|
2004-01-02 17:33:04 +01:00
|
|
|
- The descender metrics (face->size->metrics.descender) for WinFNT
|
|
|
|
|
bitmap fonts had the wrong sign.
|
|
|
|
|
|
2004-04-21 09:36:38 +02:00
|
|
|
- The (emulated) `seac' support for CFF fonts was broken.
|
2004-02-01 01:49:56 +01:00
|
|
|
|
2004-04-21 09:36:38 +02:00
|
|
|
- The `flex' operator didn't work for CFF fonts.
|
2004-02-01 01:49:56 +01:00
|
|
|
|
2004-02-24 08:52:45 +01:00
|
|
|
- PS glyphs which use the `hintmask' operator haven't been
|
|
|
|
|
rendered correctly in some cases.
|
2004-02-21 17:47:20 +01:00
|
|
|
|
2004-02-08 17:30:37 +01:00
|
|
|
- Metrics for BDF and PCF bitmap font formats have been fixed.
|
|
|
|
|
|
2004-04-16 11:56:30 +02:00
|
|
|
- Autohinting is now disabled for glyphs which are vertically
|
|
|
|
|
distorted or mirrored (using a transformation matrix). This
|
|
|
|
|
fixes a bug which produced zero-height glyphs.
|
|
|
|
|
|
2004-02-08 23:45:48 +01:00
|
|
|
- The `freetype-config' script now handles --prefix and
|
|
|
|
|
--exec-prefix correctly; it also returns the proper --rpath (or
|
|
|
|
|
-R) value if FreeType has been built as a shared library.
|
|
|
|
|
|
2003-11-13 11:19:27 +01:00
|
|
|
|
|
|
|
|
II. IMPORTANT CHANGES
|
|
|
|
|
|
|
|
|
|
- Both PCF and BDF drivers now handle the SETWIDTH_NAME and
|
|
|
|
|
ADD_STYLE_NAME properties. Values are appended to
|
|
|
|
|
face->style_name; example: `Bold SemiCondensed'.
|
|
|
|
|
|
2004-03-05 10:26:24 +01:00
|
|
|
- The PCF driver now handles bitmap fonts compressed with the LZW
|
|
|
|
|
algorithm (extension .pcf.Z, compressed with `compress').
|
|
|
|
|
|
2003-12-17 22:57:56 +01:00
|
|
|
- A new API function `FT_Get_CMap_Language_ID' (declared in
|
|
|
|
|
`tttables.h') is available to get the language ID of a
|
|
|
|
|
TrueType/SFNT cmap.
|
|
|
|
|
|
2004-01-23 20:52:40 +01:00
|
|
|
- The hexadecimal format of data after the `StartData' command in
|
|
|
|
|
CID-keyed Type 1 fonts is now supported. While this can't occur
|
|
|
|
|
in file-based fonts, it can happen in document-embedded
|
|
|
|
|
resources of PostScript documents.
|
|
|
|
|
|
2004-03-05 10:26:24 +01:00
|
|
|
- Embedded bitmaps in SFNT-based CFF fonts are now supported.
|
|
|
|
|
|
2004-02-24 08:52:45 +01:00
|
|
|
- A simple API is now available to control FreeType's tracing
|
|
|
|
|
mechanism if compiled with FT_DEBUG_LEVEL_TRACE. See the file
|
|
|
|
|
`ftdebug.h' for more details.
|
|
|
|
|
|
2004-02-25 22:17:49 +01:00
|
|
|
- YAMATO Masatake contributed improved handling of MacOS resource
|
|
|
|
|
forks on non-MacOS platforms (for example, Linux can mount MacOS
|
|
|
|
|
file systems).
|
|
|
|
|
|
2004-02-26 22:56:27 +01:00
|
|
|
- Support for MacOS has been improved; there is now a new function
|
|
|
|
|
`FT_New_Face_From_FSSpec' similar to `FT_New_Face' except that
|
|
|
|
|
it accepts an FSSpec instead of a path.
|
|
|
|
|
|
2003-12-26 08:26:08 +01:00
|
|
|
- The cache sub-system has been rewritten.
|
|
|
|
|
|
|
|
|
|
- There is now support for deinstallation of faces.
|
|
|
|
|
|
|
|
|
|
- A new API function `FTC_Manager_RemoveFaceID' has been added
|
|
|
|
|
to delete all `idle' nodes that correspond to a given
|
|
|
|
|
FTC_FaceID. All `locked' nodes (i.e., those with a reference
|
|
|
|
|
count > 0), will be modified to prevent them from appearing in
|
|
|
|
|
further lookups (they will be cleaned normally when their
|
|
|
|
|
reference count reaches 0).
|
|
|
|
|
|
|
|
|
|
- There is now support for point scaling (i.e., providing
|
|
|
|
|
character sizes in points + dpis, instead of pixels).
|
|
|
|
|
|
|
|
|
|
- Three abstract cache classes are now available:
|
|
|
|
|
|
|
|
|
|
FTC_GCache: Used to store one glyph item per cache node,
|
|
|
|
|
with the ability to group common attributes into
|
|
|
|
|
`families'. This replaces the old
|
|
|
|
|
FTC_GlyphCache class.
|
|
|
|
|
|
|
|
|
|
FTC_ICache: Used to store one FT_Glyph per cache node. This
|
|
|
|
|
extends FTC_GCache. Family definition, family
|
|
|
|
|
comparison, and glyph loading are however left
|
|
|
|
|
to sub-classes.
|
|
|
|
|
|
|
|
|
|
FTC_SCache: Used to store up to 16 small bitmaps per cache
|
|
|
|
|
node. This extends FTC_GCache. Family
|
|
|
|
|
definition, family comparison and glyph loading
|
|
|
|
|
are however left to sub-classes.
|
|
|
|
|
|
|
|
|
|
- The file `src/cache/ftcbasic.c' implements:
|
|
|
|
|
|
|
|
|
|
FTC_ImageCache: Extends FTC_ICache; implements family
|
|
|
|
|
definitions and glyph loading similar to the
|
|
|
|
|
old API.
|
|
|
|
|
|
|
|
|
|
FTC_SBitCache: Extends FTC_SCache, implements family
|
|
|
|
|
definitions and glyph loading similar to the
|
|
|
|
|
old API
|
|
|
|
|
|
|
|
|
|
Client applications should be able to extend FTC_GCache,
|
|
|
|
|
FTC_ICache, or FTC_SCache much more easily (i.e., less code to
|
|
|
|
|
write, and less callbacks). For example, one could envision
|
|
|
|
|
caches that are capable of storing transformed (obliqued),
|
|
|
|
|
stroked, emboldened, or colored glyph images. Use
|
|
|
|
|
`ftcbasic.c' as an example.
|
|
|
|
|
|
|
|
|
|
- All public APIs are now in `include/freetype/ftcache.h', (to
|
|
|
|
|
be accessed as `FT_CACHE_H'). The contents of
|
|
|
|
|
`include/freetype/cache/' is only needed by applications that
|
|
|
|
|
wish to implement their own caches.
|
|
|
|
|
|
|
|
|
|
- There were some major performance improvements through the use
|
|
|
|
|
of various programming tricks. Cache hits are up to 70%
|
|
|
|
|
faster than in the old code.
|
|
|
|
|
|
2007-01-17 13:45:26 +01:00
|
|
|
- The FTC_CMapCache has been simplified. Charmaps can only be
|
2003-12-26 08:26:08 +01:00
|
|
|
accessed by index right now. There is also a new API named
|
|
|
|
|
`FT_Charmap_GetIndex' for this purpose.
|
|
|
|
|
|
|
|
|
|
- The demo programs have been updated to the new code. The
|
|
|
|
|
previous versions will not work with the current one.
|
|
|
|
|
|
2004-03-20 15:26:38 +01:00
|
|
|
- Using an invalid face index in FT_Open_Face and friends now
|
|
|
|
|
causes an error even if the font contains a single face only.

I. IMPORTANT BUG FIXES
|
|
|
|
|
|
|
|
|
|
- Updated to newest libtool version, fixing build problems on
|
|
|
|
|
various platforms.
|
|
|
|
|
|
|
|
|
|
- On Unix platforms, `make install' didn't copy the correct
|
|
|
|
|
`ftconfig.h' file.
|
|
|
|
|
|
|
|
|
|
Note that version 2.1.7 contains the same library C source code as

|
|
|
|
version 2.1.6.

|
2003-09-01 23:18:03 +02:00
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
- The PFR font driver didn't load kerning tables correctly, and
|
|
|
|
|
the functions in FT_PFR_H didn't work at all.
|
2003-09-01 23:18:03 +02:00
|
|
|
|
2003-09-20 19:23:36 +02:00
|
|
|
- Type 1 font files in binary format (PFB) with an end-of-file
|
|
|
|
|
indicator weren't accepted by the FreeType engine.
|
|
|
|
|
|
2003-10-23 18:24:10 +02:00
|
|
|
- Fonts which contain /PaintType and /StrokeWidth no longer cause
|
|
|
|
|
a segfault. This bug has been introduced in version 2.1.5.
|
|
|
|
|
|
|
|
|
|
- Fonts loaded with FT_LOAD_RENDER no longer cause strange
|
|
|
|
|
results. This bug has been introduced in version 2.1.5.
|
|
|
|
|
|
|
|
|
|
- Some Windows (bitmap) FNT/FON files couldn't be handled
|
|
|
|
|
correctly.

II. IMPORTANT CHANGES
|
2003-09-01 23:18:03 +02:00
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
- The internal module API has been heavily changed in favor of
|
|
|
|
|
massive simplifications within the font engine. This also means
|
|
|
|
|
that authors of third-party modules must adapt their code to the
|
2003-11-09 09:37:14 +01:00
|
|
|
new scheme.
|
|
|
|
|
|
|
|
|
|
NOTE: THE NEW SCHEME IS NOT COMPLETED YET. PLEASE WAIT UNTIL A
|
|
|
|
|
FINAL ANNOUNCEMENT!
|
2003-09-01 23:18:03 +02:00
|
|
|
|
2003-10-23 18:24:10 +02:00
|
|
|
- The PostScript parser has been enhanced to handle comments and
|
|
|
|
|
strings correctly. Additionally, more syntax forms are
|
|
|
|
|
recognized.
|
|
|
|
|
|
2003-11-09 09:37:14 +01:00
|
|
|
- Added the optional unpatented hinting system for TrueType. It
|
|
|
|
|
allows typefaces which need hinting to produce correct glyph
|
|
|
|
|
forms (e.g., Chinese typefaces from Dynalab) to work acceptably
|
|
|
|
|
without infringing Apple patents. This system is compiled only
|
|
|
|
|
if TT_CONFIG_OPTION_COMPILE_UNPATENTED_HINTING is defined in
|
|
|
|
|
ftoption.h (activated by default).

III. MISCELLANEOUS
|
|
|
|
|
|
|
|
|
|
- There is now a guard in the public header files to protect
|
|
|
|
|
against inclusion of freetype.h from FreeType 1.
|
|
|
|
|
|
|
|
|
|
- Direct inclusion of freetype.h and other public header files no
|
|
|
|
|
longer works. You have to use the documented scheme
|
|
|
|
|
|
|
|
|
|
#include <ft2build.h>
|
|
|
|
|
#include FT_FREETYPE_H
|
2003-07-25 07:57:21 +02:00
|
|
|
|
2003-11-09 09:37:14 +01:00
|
|
|
to load freetype.h with a symbolic name. This protects against
|
|
|
|
|
renaming of public header files (which shouldn't happen but
|
|
|
|
|
actually has, avoiding two public header files with the same
|
|
|
|
|
name).

I. IMPORTANT BUG FIXES
|
|
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
- Parsing the /CIDFontName field now removes the leading slash to
|
2003-07-25 07:57:21 +02:00
|
|
|
be in sync with other font drivers.
|
|
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
- gzip support was buggy. Some fonts could not be read.
|
2003-07-25 07:57:21 +02:00
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
- Fonts which have nested subglyphs more than one level deep no
|
2003-07-25 07:57:21 +02:00
|
|
|
longer cause a segfault.
|
|
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
- Creation of synthetic cmaps for fonts in CFF format was broken
|
2003-07-25 07:57:21 +02:00
|
|
|
partially.
|
|
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
- Numeric font dictionary entries for synthetic fonts are no
|
|
|
|
|
longer overwritten.
|
2003-07-25 07:57:21 +02:00
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
- The font matrix wasn't applied to the advance width for Type1,
|
2003-10-23 18:24:10 +02:00
|
|
|
CID, and CFF fonts. This caused problems when loading certain
|
|
|
|
|
synthetic Type 1 fonts like `Helvetica Narrow'.
|
2003-08-06 06:40:48 +02:00
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
- The test for the charset registry in BDF and PCF fonts is now
|
2003-07-25 07:57:21 +02:00
|
|
|
case-insensitive.
|
|
|
|
|
|
2003-10-23 18:24:10 +02:00
|
|
|
- FT_Vector_Rotate sometimes returned strange values due to
|
|
|
|
|
rounding errors.
|
2003-07-25 07:57:21 +02:00
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
- The PCF driver now returns the correct number of glyphs
|
|
|
|
|
(including an artificial `notdef' glyph at index 0).
|
2003-07-25 07:57:21 +02:00
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
- FreeType now supports buggy CMaps which are contained in many
|
|
|
|
|
CJK fonts from Dynalab.
|
2003-07-25 07:57:21 +02:00
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
- Opening an invalid font on a Mac caused a segfault due to
|
2003-07-25 07:57:21 +02:00
|
|
|
double-freeing memory.
|
|
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
- BDF fonts with more than 32768 glyphs weren't supported
|
|
|
|
|
properly.
|
2003-07-25 07:57:21 +02:00

|
|
|

|
II. IMPORTANT CHANGES
|
|
|
|
|
|
|
|
|
|
- Accessing bitmap font formats has been synchronized. To do that
|
2003-09-12 21:38:13 +02:00
|
|
|
the FT_Bitmap_Size structure has been extended to contain new
|
2003-07-25 07:57:21 +02:00
|
|
|
fields `size', `x_ppem', and `y_ppem'.
|
|
|
|
|
|
|
|
|
|
- The FNT driver now returns multiple faces, not multiple strikes.
|
|
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
- The `psnames' module has been updated to the Adobe Glyph List
|
2003-07-25 07:57:21 +02:00
|
|
|
version 2.0.
|
|
|
|
|
|
|
|
|
|
- The `psnames' module now understands `uXXXX[X[X]]' glyph names.
|
|
|
|
|
|
|
|
|
|
- The algorithm for guessing the font style has been improved.
|
|
|
|
|
|
2003-12-17 22:57:56 +01:00
|
|
|
- For fonts in SFNT format, root->height is no longer increased if
|
2003-09-12 21:38:13 +02:00
|
|
|
the line gap is zero. There exist fonts (containing e.g. form
|
|
|
|
|
drawing characters) which intentionally have a zero line gap
|
|
|
|
|
value.
|
2003-07-25 07:57:21 +02:00
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
- ft_glyph_bbox_xxx flags are now deprecated in favour of
|
2003-07-25 07:57:21 +02:00
|
|
|
FT_GLYPH_BBOX_XXX.
|
|
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
- ft_module_xxx flags are now deprecated in favour of
|
|
|
|
|
FT_MODULE_XXX.

|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
- FT_ENCODING_MS_{SJIS,GB2312,BIG5,WANSUNG,JOHAB} are now
|
|
|
|
|
deprecated in favour of
|
2017-01-25 05:56:59 +01:00
|
|
|
FT_ENCODING_{SJIS,GB2312,BIG5,WANSUNG,JOHAB} -- those encodings
|
2003-09-12 21:38:13 +02:00
|
|
|
are not specific to Microsoft.

III. MISCELLANEOUS
|
|
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
- The autohinter has been further improved; for example, `m'
|
|
|
|
|
glyphs now retain its vertical symmetry.
|
2003-07-25 07:57:21 +02:00
|
|
|
|
|
|
|
|
- Partial support of Mac fonts on non-Mac platforms.
|
|
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
- `make refdoc' (after first `make') builds the HTML
|
|
|
|
|
documentation. You need Python for this.
|
2003-07-25 07:57:21 +02:00
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
- The make build system should now work more reliably on DOS-like
|
2003-07-25 07:57:21 +02:00
|
|
|
platforms.
|
|
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
- Support for EMX gcc and Watson C/C++ compilers on MS-DOS has
|
|
|
|
|
been added.
|
2003-07-25 07:57:21 +02:00
|
|
|
|
|
|
|
|
- Better VMS build support.
|
|
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
- Support for the pkg-config package by providing a `freetype.pc'
|
2003-07-25 07:57:21 +02:00
|
|
|
file.
|
|
|
|
|
|
|
|
|
|
- New configure option --with-old-mac-fonts for Darwin.
|
|
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
- Some source files have been renamed (mainly to fit into the 8.3
|
2003-07-25 07:57:21 +02:00
|
|
|
naming scheme).

I. IMPORTANT BUG FIXES
|
|
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
- Updated to newest libtool version, fixing build problems on

|
2003-01-24 09:30:36 +01:00
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
- A fix in the Gzip stream reader: It couldn't read certain .gz
|
|
|
|
|
files properly due to a small typo. In certain cases, FreeType
|
|
|
|
|
could also loop endlessly when trying to load tiny gzipped
|
|
|
|
|
files.
|
2003-01-24 09:30:36 +01:00
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
- The configure script now tries to use the system-wide zlib when
|
|
|
|
|
it finds one (instead of the copy found in src/gzip). And
|
2007-01-09 11:37:36 +01:00
|
|
|
`freetype-config' has been updated to return relevant flags in
|
|
|
|
|
this case when invoked with `--libs' (e.g. `-lzlib').
|
2003-01-24 09:30:36 +01:00
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
- Certain fonts couldn't be loaded by 2.1.3 because they lacked a
|
|
|
|
|
Unicode charmap (e.g. SYMBOL.TTF). FreeType erroneously
|
|
|
|
|
rejected them.

- The CFF loader was modified to accept fonts which only contain a
|
2003-09-12 21:38:13 +02:00
|
|
|
subset of their reference charset. This prevented the correct
|
|
|
|
|
use of PDF-embedded fonts.
|
2003-01-24 09:30:36 +01:00
|
|
|
|
2003-04-21 15:30:27 +02:00
|
|
|
- The logic to detect Unicode charmaps has been modified. This is
|
2003-09-12 21:38:13 +02:00
|
|
|
required to support fonts which include both 16-bit and 32-bit
|
|
|
|
|
charmaps (like very recent asian ones) using the new 10 and 12
|
|
|
|
|
SFNT formats.
|
2003-01-24 09:30:36 +01:00
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
- The TrueType loader now limits the depth of composite glyphs.
|
|
|
|
|
This is necessary to prevent broken fonts to break the engine by
|
|
|
|
|
blowing the stack with recursive glyph definitions.
|
2003-01-24 09:30:36 +01:00
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
- The CMap cache is now capable of managing UCS-4 character codes
|
|
|
|
|
that are mapped through extended charmaps in recent
|
|
|
|
|
TrueType/OpenType fonts.
|
2003-02-25 22:44:11 +01:00
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
- The cache sub-system now properly manages out-of-memory
|
|
|
|
|
conditions instead of blindly reporting them to the caller.
|
|
|
|
|
This means that it will try to empty the cache before restarting
|
|
|
|
|
its allocations to see if that can help.
|
2003-03-20 08:04:40 +01:00
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
- The PFR driver didn't return the list of available embedded
|
|
|
|
|
bitmaps properly.
|
2003-02-25 22:44:11 +01:00
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
- There was a nasty memory leak when using embedded bitmaps in
|
|
|
|
|
certain font formats.

II. IMPORTANT CHANGES
|
|
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
- David Chester contributed some enhancements to the auto-hinter
|
|
|
|
|
that significantly increase the quality of its output. The
|
|
|
|
|
Postscript hinter was also improved in several ways.
|
2003-01-24 09:30:36 +01:00
|
|
|
|
2003-04-21 15:30:27 +02:00
|
|
|
- The FT_RENDER_MODE_LIGHT render mode was implemented.
|
2003-01-24 09:30:36 +01:00
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
- A new API function called `FT_Get_BDF_Property' has been added
|
|
|
|
|
to FT_BDF_H to retrieve BDF properties from BDF _and_ PCF font
|
|
|
|
|
files. THIS IS STILL EXPERIMENTAL, since it hasn't been
|
|
|
|
|
properly tested yet.
|
2003-01-24 09:30:36 +01:00
|
|
|
|
2003-04-21 15:30:27 +02:00
|
|
|
- A Windows FNT specific API has been added, mostly to access font
|
|
|
|
|
headers. This is used by Wine.
|
2003-01-24 09:30:36 +01:00
|
|
|
|
2007-01-09 11:37:36 +01:00
|
|
|
- TrueType tables without an `hmtx' table are now tolerated when
|
2003-09-12 21:38:13 +02:00
|
|
|
an incremental interface is used. This happens for certain
|
|
|
|
|
Type42 fonts passed from Ghostscript to FreeType.
|
2003-01-24 09:30:36 +01:00
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
- The PFR font driver is now capable of returning the font family
|
|
|
|
|
and style names when they are available (instead of the sole
|
2007-01-09 11:37:36 +01:00
|
|
|
`FontID'). This is performed by parsing an *undocumented*
|
2003-09-12 21:38:13 +02:00
|
|
|
portion of the font file!
|
2003-04-21 15:30:27 +02:00
|
|
|
|
2003-02-25 22:44:11 +01:00

III. MISCELLANEOUS
|
|
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
- The path stroker in FT_STROKER_H has entered beta stage. It now
|
|
|
|
|
works very well, but its interface might change a bit in the
|
|
|
|
|
future. More on this in later releases.
|
2003-04-21 15:30:27 +02:00
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
- The documentation for FT_Size_Metrics didn't appear properly in
|
|
|
|
|
the API reference.
|
2003-01-24 09:30:36 +01:00
|
|
|
|
2003-04-21 15:30:27 +02:00
|
|
|
- The file docs/VERSION.DLL has been updated to explain versioning
|
2003-09-12 21:38:13 +02:00
|
|
|
with FreeType (i.e., comparing release/libtool/so numbers, and
|
|
|
|
|
how to use them in autoconf scripts).
|
2003-01-24 09:30:36 +01:00
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
- The installation documentation has been seriously revamped.
|
2007-01-09 11:37:36 +01:00
|
|
|
Everything is now in the `docs' directory.
|

CHANGES BETWEEN 2.1.3 and 2.1.2
|
2002-08-30 01:18:56 +02:00
|
|
|
|
|
|
|
|
I. IMPORTANT BUG FIXES
|
|
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
- FT_Vector_Transform had been incorrectly modified in 2.1.2,
|
|
|
|
|
resulting in incorrect transformations being applied (for
|
|
|
|
|
example, rotations were processed in opposite angles).
|
2002-08-30 01:18:56 +02:00
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
- The format 8 and 12 TrueType charmap enumeration routines have
|
|
|
|
|
been fixed (FT_Get_Next_Char returned invalid values).
|
2002-08-30 01:18:56 +02:00
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
- The PFR font driver returned incorrect advance widths if the
|
|
|
|
|
outline and metrics resolution defined in the font file were
|
|
|
|
|
different.
|
2002-08-30 01:18:56 +02:00
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
- FT_Glyph_To_Bitmap now returns successfully when called with an
|
2002-09-05 17:10:54 +02:00
|
|
|
FT_BitmapGlyph argument (it previously returned an error).
|
2002-08-30 01:18:56 +02:00
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
- A bug in the Type 1 loader that prevented valid font bounding
|
|
|
|
|
boxes to be loaded from multiple master fonts.
|
2002-08-30 01:18:56 +02:00
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
- The SFNT validation code has been rewritten. FreeType can now
|
2007-01-09 11:37:36 +01:00
|
|
|
load `broken' fonts that were usable on Windows, but not with
|
2003-09-12 21:38:13 +02:00
|
|
|
previous versions of the library.
|
2002-08-30 01:18:56 +02:00
|
|
|
|
2002-09-05 17:10:54 +02:00
|
|
|
- The computation of bearings in the BDF driver has been fixed.
|
2002-08-30 01:18:56 +02:00
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
- The Postscript hinter crashed when trying to hint certain glyphs
|
|
|
|
|
(more precisely, when trying to apply hints to an empty glyph
|
|
|
|
|
outline).
|
2002-09-18 09:53:22 +02:00
|
|
|
|
2007-01-09 11:37:36 +01:00
|
|
|
- The TrueType glyph loader now supports composites in `Apple
|
|
|
|
|
format' (they differ slightly from Microsoft/OpenType ones in
|
2003-09-12 21:38:13 +02:00
|
|
|
the way transformation offsets are computed).
|
2002-09-18 13:32:12 +02:00
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
- FreeType was very slow at opening certain asian CID/CFF fonts,
|
|
|
|
|
due to fixed increment in dynamic array re-allocations. This
|
|
|
|
|
has been changed to exponential behaviour to get acceptable
|
|
|
|
|
performance.

II. IMPORTANT CHANGES
|
2002-08-30 01:18:56 +02:00
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
- The PCF driver now supports gzip-compressed font files natively.
|
|
|
|
|
This means that you will be able to use all these bitmap fonts
|
|
|
|
|
that come with XFree86 with FreeType (and libXft/libXft2, by
|
|
|
|
|
extension).
|
2002-11-14 00:28:08 +01:00
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
- The automatic and postscript hinters have both been updated.
|
|
|
|
|
This results in a relatively important increase of rendering
|
2007-01-17 13:45:26 +01:00
|
|
|
quality since many nasty defaults have been suppressed. Please
|
2003-09-12 21:38:13 +02:00
|
|
|
visit the web page:
|
2002-09-18 09:53:22 +02:00

|
|
|
|
2002-09-18 13:32:12 +02:00
|
|
|
for additional details on this topic.
|
2002-09-18 09:53:22 +02:00
|
|
|
|
2007-01-09 11:37:36 +01:00
|
|
|
- The `load_flags' parameter of `FT_Load_Glyph' is now an FT_Int32
|
2003-09-12 21:38:13 +02:00
|
|
|
(instead of just being an FT_Int). This breaks source and
|
|
|
|
|
binary compatibility for 16bit systems only, while retaining
|
|
|
|
|
both of them for 32 and 64 bit ones.
|
2002-09-25 02:10:27 +02:00
|
|
|
|
|
|
|
|
Some new flags have been added consequently:
|
|
|
|
|
|
|
|
|
|
FT_LOAD_NO_AUTOHINT :: Disable the use of the auto-hinter
|
|
|
|
|
(but not native format hinters).
|
|
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
FT_LOAD_TARGET_NORMAL :: Hint and render for normal
|
|
|
|
|
anti-aliased displays.
|
2002-09-25 02:10:27 +02:00
|
|
|
|
|
|
|
|
FT_LOAD_TARGET_MONO :: Hint and render for 1-bit displays.
|
|
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
FT_LOAD_TARGET_LCD :: Hint and render for horizontal RGB or
|
2018-02-17 10:34:47 +01:00
|
|
|
BGR subpixel displays (like LCD
|
2003-09-12 21:38:13 +02:00
|
|
|
screens). THIS IS STILL
|
|
|
|
|
EXPERIMENTAL!
|
2002-09-25 02:10:27 +02:00
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
FT_LOAD_TARGET_LCD_V :: Same as FT_LOAD_TARGET_LCD, for
|
2018-02-17 10:34:47 +01:00
|
|
|
vertical subpixel displays (like
|
2003-09-12 21:38:13 +02:00
|
|
|
rotated LCD screens). THIS IS STILL
|
|
|
|
|
EXPERIMENTAL!
|
2002-09-25 02:10:27 +02:00
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
FT_LOAD_MONOCHROME is still supported, but only affects
|
|
|
|
|
rendering, not the hinting.
|
2002-09-25 02:10:27 +02:00
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
Note that the `ftview' demo program available in the `ft2demos'
|
|
|
|
|
package has been updated to support LCD-optimized display on
|
|
|
|
|
non-paletted displays (under Win32 and X11).
|
2002-09-25 02:10:27 +02:00
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
- The PFR driver now supports embedded bitmaps (all formats
|
|
|
|
|
supported), and returns correct kerning metrics for all glyphs.
|
2002-10-05 17:00:36 +02:00
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
- The TrueType charmap loader now supports certain `broken' fonts
|
|
|
|
|
that load under Windows without problems.
|
2002-09-25 02:10:27 +02:00
|
|
|
|
2002-09-27 20:17:17 +02:00
|
|
|
- The cache API has been slightly modified (it's still a beta!):
|
2002-09-25 02:10:27 +02:00
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
- The type FTC_ImageDesc has been removed; it is now replaced
|
|
|
|
|
by FTC_ImageTypeRec. Note that one of its fields is a
|
|
|
|
|
`load_flag' parameter for FT_Load_Glyph.
|
2002-09-25 02:10:27 +02:00
|
|
|
|
2007-01-09 11:37:36 +01:00
|
|
|
- The field `num_grays' of FT_SBitRec has been changed to
|
|
|
|
|
`max_grays' in order to fit within a single byte. Its
|
2003-09-12 21:38:13 +02:00
|
|
|
maximum value is thus 255 (instead of 256 as previously).
|
2002-09-25 02:10:27 +02:00
|
|

III. MISCELLANEOUS
|
|
|
|
|
|
2007-01-09 11:37:36 +01:00
|
|
|
- Added support for the DESTDIR variable during `make install'.
|
2003-09-12 21:38:13 +02:00
|
|
|
This simplifies packaging of FreeType.
|
2002-09-18 09:53:22 +02:00
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
- Included modified copies of the ZLib sources in `src/gzip' in
|
|
|
|
|
order to support gzip-compressed PCF fonts. We do not use the
|
|
|
|
|
system-provided zlib for now, though this is a probable
|
|
|
|
|
enhancement for future releases.
|
2002-11-14 00:28:08 +01:00
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
- The DocMaker tool used to generate the on-line API reference has
|
|
|
|
|
been completely rewritten. It is now located in
|
2007-01-09 11:37:36 +01:00
|
|
|
`src/tools/docmaker/docmaker.py'. Features:
|
2002-09-18 09:53:22 +02:00
|
|
|
|
|
|
|
|
- better cross-referenced output
|
|
|
|
|
- more polished output
|
2003-09-12 21:38:13 +02:00
|
|
|
- uses Python regular expressions (though it didn't speed the
|
2002-09-18 13:32:12 +02:00
|
|
|
program)
|
2003-09-12 21:38:13 +02:00
|
|
|
- much more modular structure, which allows for different
|
2007-01-09 11:37:36 +01:00
|
|
|
`backends' in order to generate HTML, XML, or whatever
|
2003-09-12 21:38:13 +02:00
|
|
|
format.
|
2002-09-18 09:53:22 +02:00
|
|
|
|
2002-09-18 13:32:12 +02:00
|
|
|
One can regenerate the API reference by calling:

|
2002-09-05 17:10:54 +02:00
|
|
|
- A new, experimental, support for incremental font loading (i.e.,
|
2003-09-12 21:38:13 +02:00
|
|
|
loading of fonts where the glyphs are not in the font file
|
|
|
|
|
itself, but provided by an external component, like a Postscript
|
|
|
|
|
interpreter) has been added by Graham Asher. This is still work
|
|
|
|
|
in progress, however.
|
|
|
|
|
|
|
|
|
|
- A new, EXPERIMENTAL, path stroker has been added. It doesn't
|
|
|
|
|
suffer from severe rounding errors and treat bezier arcs
|
|
|
|
|
directly. Still work in progress (i.e. not part of the official
|
|
|
|
|
API). See the file <freetype/ftstroker.h> for some of the
|
|
|
|
|
details.

|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
- The massive re-formatting of sources and internal re-design is
|
|
|
|
|
still under-way. Many internal functions, constants, and types
|
|
|
|
|
have been renamed.

I. IMPORTANT BUG FIXES
|
|
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
- Many font drivers didn't select a Unicode charmap by default
|
|
|
|
|
when a new face was opened (with the FT_CONFIG_OPTION_USE_CMAPS
|
|
|
|
|
options enabled), causing many applications to not be able to
|
|
|
|
|
display text correctly with the 2.1.x releases.
|
2002-08-30 01:18:56 +02:00
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
- The PFR driver had a bug in its composite loading code that
|
|
|
|
|
produces incorrectly placed accents with many fonts.
|
2002-08-30 01:18:56 +02:00
|
|
|
|
2002-06-22 15:35:41 +02:00
|
|
|
- The Type42 driver crashed sometimes due to a nasty bug.
|
2002-08-30 01:18:56 +02:00
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
- The Type 1 custom encoding charmap didn't handle the case where
|
|
|
|
|
the first glyph index wasn't 0.
|
2002-06-21 09:33:23 +02:00
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
- A serious typo in the TrueType composite loader produced
|
2007-01-09 11:37:36 +01:00
|
|
|
incorrectly placed glyphs in fonts like `Wingdings' and a few
|
2003-09-12 21:38:13 +02:00
|
|
|
others.

II. MISCELLANEOUS
|
|
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
- The Win32 Visual C++ project file has been updated to include
|
|
|
|
|
the PFR driver as well.
|
2002-06-21 09:33:23 +02:00
|
|
|
|
2007-01-09 11:37:36 +01:00
|
|
|
- `freetype.m4' is now installed by default by `make install' on
|
2003-09-12 21:38:13 +02:00
|
|
|
Unix systems.
|
2002-06-21 09:33:23 +02:00
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
- The function FT_Get_PS_Font_Info now works with CID and Type42
|
|
|
|
|
fonts as well.

CHANGES BETWEEN 2.1.1 and 2.1.0
|
2002-05-29 01:40:37 +02:00
|
|
|
|
|
|
|
|
I. IMPORTANT BUG FIXES
|
|
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
- The `version_info' returned by `freetype-config' in 2.1.0
|
|
|
|
|
returned an invalid value. It now returns 9:1:3 (2.0.9 returned
|
|
|
|
|
9:0:3).
|
2002-05-29 01:40:37 +02:00
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
- Version 2.1.0 couldn't be linked against applications on Win32
|
|
|
|
|
and Amiga systems due to a new debug function that wasn't
|
|
|
|
|
properly propagated to the system-specific directory in
|
|
|
|
|
`builds'.
|
2002-05-29 01:40:37 +02:00
|
|
|
|
2002-05-30 21:22:14 +02:00
|
|
|
- Various MacOS and Mac OS X specific fixes.
|
2002-05-29 01:40:37 +02:00
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
- Fixed a bug in the TrueType charmap validation routines that
|
|
|
|
|
made version 2.1.0 too restrictive -- many popular fonts have
|
|
|
|
|
been rejected.
|
2002-05-29 01:40:37 +02:00
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
- There was still a very small difference between the monochrome
|
|
|
|
|
glyph bitmaps produced by FreeType 1.x and FreeType 2.x with the
|
|
|
|
|
bytecode interpreter enabled. This was caused by an invalid
|
|
|
|
|
flag setting in the TrueType glyph loader, making the rasterizer
|
2007-01-17 13:45:26 +01:00
|
|
|
change its drop-out control mode. Now the results should
|
2003-09-12 21:38:13 +02:00
|
|
|
_really_ be completely identical.
|
2002-05-29 01:40:37 +02:00
|
|
|
|
2002-05-30 21:22:14 +02:00
|
|
|
- The TrueType name table loader has been improved to support many
|
2003-09-12 21:38:13 +02:00
|
|
|
popular though buggy Asian fonts. It now ignores empty name
|
|
|
|
|
entries, invalid pointer offsets and a few other incorrect
|
|
|
|
|
subtleties. Moreover, name strings are now loaded on demand,
|
|
|
|
|
which reduces the memory load of many faces (e.g. the ARIAL.TTF
|
|
|
|
|
font file contains a 10kByte name table with 70 names).
|
2002-05-29 01:40:37 +02:00
|
|
|
|
2002-05-30 21:22:14 +02:00
|
|
|
- Fixed a bug in the Postscript hinter that prevented family blues
|
2002-05-29 01:40:37 +02:00
|
|
|
substitution to happen correctly.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
II. NEW FEATURES
|
|
|
|
|
|
2002-05-30 21:22:14 +02:00
|
|
|
- Three new font drivers in this release:
|
2002-05-29 01:40:37 +02:00
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
* A BDF font driver, contributed by Franco Zappa Nardelli,
|
|
|
|
|
heavily modified by Werner Lemberg. It also supports
|
|
|
|
|
anti-aliased bitmaps (using a slightly extended BDF format).
|
2002-05-29 01:40:37 +02:00
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
* A Type42 font driver, contributed by Roberto Alameda. It is
|
2002-06-11 00:41:57 +02:00
|
|
|
still experimental but seems to work relatively well.
|
2002-05-29 01:40:37 +02:00
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
* A PFR font driver, contributed by David Turner himself. It
|
|
|
|
|
doesn't support PFR hinting -- note that BitStream has at
|
|
|
|
|
least two patents on this format!

III. MISCELLANEOUS
|
|
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
- The cache sub-system has been optimized in important ways.
|
|
|
|
|
Cache hits are now significantly faster. For example, using the
|
|
|
|
|
CMap cache is about twice faster than calling FT_Get_Char_Index
|
|
|
|
|
on most platforms. Similarly, using an SBit cache is about five
|
|
|
|
|
times faster than loading the bitmaps from a bitmap file, and
|
|
|
|
|
300 to 500 times faster than generating them from a scalable
|
|
|
|
|
format.
|
2002-06-11 00:41:57 +02:00
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
Note that you should recompile your sources if you designed a
|
|
|
|
|
custom cache class for the FT2 Cache subsystem, since the
|
|
|
|
|
changes performed are source, but not binary, compatible.

CHANGES BETWEEN 2.1.0 and 2.0.9
|
2002-04-15 14:01:10 +02:00
|
|
|
|
|
|
|
|
I. IMPORTANT BUG FIXES
|
|
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
- The TrueType bytecode interpreter has been fixed to produce
|
2002-04-15 15:37:29 +02:00
|
|
|
_exactly_ the same output as FreeType 1.x. Previous differences
|
2003-09-12 21:38:13 +02:00
|
|
|
were due to slightly distinct fixed-point computation routines
|
2002-04-15 14:01:10 +02:00
|
|
|
used to perform dot products and vector length measurements.
|
2002-04-15 15:37:29 +02:00
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
It seems that native TrueType hinting is _extremely_ sensitive
|
|
|
|
|
to rounding errors. The required vector computation routines
|
2007-01-09 11:37:36 +01:00
|
|
|
have been optimized and placed within the `ttinterp.c' file.
|
2002-04-15 14:01:10 +02:00
|
|
|
|
2002-04-18 00:42:13 +02:00
|
|
|
- Fixed the parsing of accelerator tables in the PCF font driver.
|
2002-05-29 01:40:37 +02:00
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
- Fixed the Type1 glyph loader routine used to compute the font's
|
2002-04-17 11:37:59 +02:00
|
|
|
maximum advance width.
|
2002-04-15 14:01:10 +02:00

II. NEW FEATURES
|
|
|
|
|
|
2002-04-15 15:37:29 +02:00
|
|
|
- The `configure' script used on Unix systems has been modified to
|
2003-09-12 21:38:13 +02:00
|
|
|
check that GNU Make is being used to build the library.
|
|
|
|
|
Otherwise, it will display a message proposing to use the
|
|
|
|
|
GNUMAKE environment variable to name it.
|
2002-04-15 15:37:29 +02:00
|
|
|
|
|
|
|
|
The Unix-specific file README.UNX has been modified accordingly.

The following internal changes have been performed within the

|
|
sources of this release:
|
2002-04-15 15:37:29 +02:00
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
- Many internal types have been renamed to increase
|
|
|
|
|
consistency. The following should be true, except for
|
|
|
|
|
public types:
|
2002-04-15 15:37:29 +02:00
|
|
|
|
2007-01-09 11:37:36 +01:00
|
|
|
* All structure types have a name ending in `Rec' (short
|
2003-09-12 21:38:13 +02:00
|
|
|
for `record').
|
2002-04-15 15:37:29 +02:00
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
* A pointer-to-structure type has the same name as the
|
2007-01-09 11:37:36 +01:00
|
|
|
structure, _without_ the `Rec' suffix.

|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
- Many internal macros have been renamed to increase
|
|
|
|
|
consistency. The following should be true:
|
2002-04-15 15:37:29 +02:00
|
|
|
|
2007-01-09 11:37:36 +01:00
|
|
|
* All macros have a name beginning with `FT_'. This
|
2003-09-12 21:38:13 +02:00
|
|
|
required a few changes like
|
2002-04-15 15:37:29 +02:00

|
|
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
* All macros are completely UPPERCASE. This required a
|
|
|
|
|
few changes like:
|
2002-04-15 15:37:29 +02:00
|
|
|
|
|
|
|
|
READ_Short => FT_READ_SHORT
|
|
|
|
|
NEXT_Short => FT_NEXT_SHORT
|
|
|
|
|
GET_ULongLE => FT_GET_ULONG_LE
|
|
|
|
|
MEM_Set => FT_MEM_SET
|
|
|
|
|
MEM_Copy => FT_MEM_COPY
|
|
|
|
|
etc.
|
|
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
* Whenever possible, all macro names follow the
|
2002-04-15 15:37:29 +02:00
|
|
|
FT_<OBJECT>_<METHOD> pattern. For example
|
|
|
|
|
|
|
|
|
|
ACCESS_Frame => FT_FRAME_ENTER
|
|
|
|
|
FORGET_Frame => FT_FRAME_EXIT
|
|
|
|
|
EXTRACT_Frame => FT_FRAME_EXTRACT
|
|
|
|
|
RELEASE_Frame => FT_FRAME_RELEASE
|
|
|
|
|
|
|
|
|
|
FILE_Pos => FT_STREAM_POS
|
|
|
|
|
FILE_Seek => FT_STREAM_SEEK
|
|
|
|
|
FILE_Read => FT_STREAM_READ
|
|
|
|
|
FILE_ReadAt => FT_STREAM_READ_AT
|
|
|
|
|
READ_Fields => FT_STREAM_READ_FIELDS
|
|
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
- Many internal functions have been renamed to follow the
|
2002-04-15 15:37:29 +02:00
|
|
|
FT_<Object>_<Method> pattern. For example:
|
|
|
|
|
|
|
|
|
|
FT_Seek_Stream => FT_Stream_Seek
|
|
|
|
|
FT_Read_Stream_At => FT_Stream_ReadAt
|
|
|
|
|
FT_Done_Stream => FT_Stream_Close
|
|
|
|
|
FT_New_Stream => FT_Stream_Open
|
|
|
|
|
FT_New_Memory_Stream => FT_Stream_OpenMemory
|
|
|
|
|
FT_Extract_Frame => FT_Stream_ExtractFrame
|
|
|
|
|
|
2007-01-09 11:37:36 +01:00
|
|
|
Note that method names do not contain `_'.
|
2002-04-15 15:37:29 +02:00
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
- The FT_ALLOC_ARRAY and FT_REALLOC_ARRAY have been replaced
|
|
|
|
|
with FT_NEW_ARRAY and FT_RENEW_ARRAY which do not take a
|
|
|
|
|
type as the fourth argument. Instead, the array element
|
|
|
|
|
type size is computed automatically from the type of the
|
|
|
|
|
target pointer used.
|
2002-04-15 15:37:29 +02:00
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
- A new object class, FT_CMap, has been introduced. These
|
|
|
|
|
internal objects are used to model character maps. This
|
|
|
|
|
eases the support of additional charmap types within the
|
|
|
|
|
engine.
|
2002-04-15 15:37:29 +02:00
|
|
|
|
2007-01-09 11:37:36 +01:00
|
|
|
- A new configuration file named `ftstdlib.h' has been added
|
2003-09-12 21:38:13 +02:00
|
|
|
to `include/freetype/config'. It is used to define aliases
|
|
|
|
|
for _every_ routine of the ISO C library that the font
|
2007-01-09 11:37:36 +01:00
|
|
|
engine uses. Each aliases has a `ft_' prefix
|
|
|
|
|
(e.g. `ft_strlen' is an alias for `strlen').
|
2002-04-15 15:37:29 +02:00
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
This is used to ease the porting of FreeType 2 to exotic
|
|
|
|
|
runtime environments where the ISO C Library isn't available
|
|
|
|
|
(e.g. XFree86 extension modules).

I. IMPORTANT BUG FIXES
|
2002-04-15 15:37:29 +02:00
|
|
|
|
2007-01-09 11:37:36 +01:00
|
|
|
- Certain fonts like `foxjump.ttf' contain broken name tables with
|
2003-09-12 21:38:13 +02:00
|
|
|
invalid entries and wild offsets. This caused FreeType to crash
|
|
|
|
|
when trying to load them.
|
2002-04-15 15:37:29 +02:00
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
The SFNT `name' table loader has been fixed to be able to
|
|
|
|
|
support these strange fonts.
|
2002-04-11 16:21:16 +02:00
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
Moreover, the code in charge of processing this table has been
|
|
|
|
|
changed to always favour Windows-formatted entries over other
|
|
|
|
|
ones. Hence, a font that works on Windows but not on the Mac
|
|
|
|
|
will load cleanly in FreeType and report accurate values for
|
|
|
|
|
Family & PostScript names.
|
2002-04-11 16:21:16 +02:00
|
|
|
|
|
|
|
|
- The CID font driver has been fixed. It unfortunately returned a
|
2003-09-12 21:38:13 +02:00
|
|
|
Postscript Font name with a leading slash, as in
|
2007-01-09 11:37:36 +01:00
|
|
|
`/MunhwaGothic-Regular'.
|
2002-04-11 16:21:16 +02:00
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
- FreeType 2 should now compile fine on AIX 4.3.3 as a shared
|
|
|
|
|
library.
|
2002-04-11 16:21:16 +02:00
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
- A bug in the Postscript hinter has been found and fixed,
|
|
|
|
|
removing un-even stem widths at small pixel sizes (like 14-17).
|
2002-04-15 15:37:29 +02:00
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
This improves the quality of a certain number of Postscript
|
|
|
|
|
fonts.

II. NEW FEATURES

2002-04-11 16:21:16 +02:00
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
- A new function named `FT_Library_Version' has been added to
|
|
|
|
|
return the current library's major, minor, and patch version
|
|
|
|
|
numbers. This is important since the macros FREETYPE_MAJOR,
|
|
|
|
|
FREETYPE_MINOR, and FREETYPE_PATCH cannot be used when the
|
|
|
|
|
library is dynamically linked by a program.
|
2002-04-11 16:21:16 +02:00
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
- Two new APIs have been added: `FT_Get_First_Char' and
|
2002-04-11 21:55:58 +02:00
|
|
|
`FT_Get_Next_Char'.
|
2002-04-15 15:37:29 +02:00
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
Together, these can be used to iterate efficiently over the
|
|
|
|
|
currently selected charmap of a given face. Read the API
|
|
|
|
|

|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
- The FreeType sources are under heavy internal re-factoring. As
|
2007-01-09 11:37:36 +01:00
|
|
|
a consequence, we have created a branch named `STABLE' on the
|
2003-09-12 21:38:13 +02:00
|
|
|
CVS to hold all future releases/fixes in the 2.0.x family.

|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
The HEAD branch now contains the re-factored sources and
|
|
|
|
|
shouldn't be used for testing or packaging new releases. In
|
|
|
|
|
case you would like to access the 2.0.9 sources from our CVS
|
|
|
|
|
repository, use the tag `VER-2-0-9'.

I. IMPORTANT BUG FIXES
|
2002-04-15 15:37:29 +02:00
|
|
|
|
2007-01-09 11:37:36 +01:00
|
|
|
- There was a small but nasty bug in `freetype-config.in' which
|
|
|
|
|
caused the `freetype-config' script to fail on Unix.
|
2002-04-15 15:37:29 +02:00
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
This didn't prevent the installation of the library or even its
|
|
|
|
|
execution, but caused problems when trying to compile many Unix
|
|
|
|
|
packages that depend on it.
|
2002-04-15 15:37:29 +02:00
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
- Some TrueType or OpenType fonts embedded in PDF documents do not
|
|
|
|
|
have a 'cmap', 'post' and 'name' as is required by the
|
2002-04-11 21:55:58 +02:00
|
|
|
specification. FreeType no longer refuses to load such fonts.

I. IMPORTANT BUG FIXES
|
|
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
- Fixed two bugs in the Type 1 font driver. The first one
|
|
|
|
|
resulted in a memory leak in subtle cases. The other one caused
|
2007-01-09 11:37:36 +01:00
|
|
|
FreeType to crash when trying to load `.gsf' files (Ghostscript
|
2003-09-12 21:38:13 +02:00
|
|
|
so-called Postscript fonts).
|
2002-01-31 18:42:05 +01:00
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
(This made _many_ KDE applications crash on certain systems.
|
|
|
|
|
FreeType _is_ becoming a critical system component on Linux :-)

2002-01-31 18:42:05 +01:00
|
|
|

2002-02-01 02:20:11 +01:00

|
2007-01-09 11:37:36 +01:00
|
|
|
`builds/win32/visualc/freetype.dsp' since it didn't include the
|
2003-09-12 21:38:13 +02:00
|

|
Postscript hinter component, causing errors at build time.

2003-09-12 21:38:13 +02:00
|
|
|
- Fixed a small rendering bug in the anti-aliased renderer that
|
|
|
|
|
only occurred when trying to draw thin (less than 1 pixel)
|
|
|
|
|
strokes.

|
|
|
|
valid `freetype2.m4' for use with autoconf.

I. IMPORTANT BUG FIXES
|
|
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
- It wasn't possible to load embedded bitmaps when the auto-hinter
|
|
|
|
|
was used. This is now fixed.
|
2001-12-20 22:22:02 +01:00
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
- The TrueType font driver didn't load some composites properly
|
|
|
|
|
(the sub-glyphs were slightly shifted, and this was only
|
|
|
|
|
noticeable when using monochrome rendering).
|
2001-12-20 22:22:02 +01:00
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
- Various fixes to the auto-hinter. They merely improve the
|
|
|
|
|
output of sans-serif fonts. Note that there are still problems
|
|
|
|
|
with serifed fonts and composites (accented characters).
|
2001-12-20 22:22:02 +01:00
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
- All scalable font drivers erroneously returned un-fitted glyph
|
|
|
|
|
advances when hinting was requested. This created problems for
|
|
|
|
|
a number of layout applications. This is a very old bug that
|
|
|
|
|
got undetected mainly because most test/demo program perform
|
|
|
|
|
rounding explicitly or implicitly (through the cache).
|
2001-12-20 22:22:02 +01:00
|
|
|
|
2007-01-09 11:37:36 +01:00
|
|
|
- `FT_Glyph_To_Bitmap' did erroneously modify the source glyph in
|
2001-12-20 22:22:02 +01:00
|
|
|
certain cases.
|
|
|
|
|
|
2007-01-09 11:37:36 +01:00
|
|
|
- `glnames.py' still contained a bug that made FreeType return
|
2003-09-12 21:38:13 +02:00
|
|
|
invalid names for certain glyphs.
|
2001-12-20 22:22:02 +01:00

|
|
|
- The library crashed when loading certain Type 1 fonts like
|
2007-01-09 11:37:36 +01:00
|
|
|
`sadn.pfb' (`Stalingrad Normal'), which appear to contain
|
2003-09-12 21:38:13 +02:00
|
|
|
pathetic font info dictionaries.
|
2002-01-07 11:40:48 +01:00
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
- The TrueType glyph loader is now much more paranoid and checks
|
|
|
|
|
everything when loading a given glyph image. This was necessary
|
|
|
|
|
to avoid problems (crashes and/or memory overwrites) with broken
|
|
|
|
|
fonts that came from a really buggy automatic font converter.

II. IMPORTANT UPDATES AND NEW FEATURES
|
|
|
|
|
|
|
|
|
|
- Important updates to the Mac-specific parts of the library.
|
|
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
- The caching sub-system has been completely re-designed, and its
|
2006-03-24 12:54:53 +01:00
|
|
|
API has evolved (the old one is still supported for backward
|
2001-12-20 22:22:02 +01:00
|
|
|
compatibility).
|
|
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
The documentation for it is not yet completed, sorry. For now,
|
|
|
|
|
you are encouraged to continue using the old API. However, the
|
|
|
|
|
ftview demo program in the ft2demos package has already been
|
|
|
|
|
updated to use the new caching functions.
|
2001-12-20 22:22:02 +01:00
|
|
|
|
2007-01-09 11:37:36 +01:00
|
|
|
- A new charmap cache is provided too. See `FTC_CMapCache'. This
|
2003-09-12 21:38:13 +02:00
|
|
|
is useful to perform character code -> glyph index translations
|
|
|
|
|
quickly, without the need for an opened FT_Face.
|
2001-12-20 22:22:02 +01:00
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
- A NEW POSTSCRIPT HINTER module has been added to support native
|
|
|
|
|
hints in the following formats: PostScript Type 1, PostScript
|
|
|
|
|
CID, and CFF/CEF.
|
2001-12-20 22:22:02 +01:00
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
Please test! Note that the auto-hinter produces better results
|
|
|
|
|
for a number of badly-hinted fonts (mostly auto-generated ones)
|
|
|
|
|
though.
|
2001-12-20 22:22:02 +01:00
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
- A memory debugger is now part of the standard FreeType sources.
|
|
|
|
|
To enable it, define FT_DEBUG_MEMORY in
|
|
|
|
|
<freetype/config/ftoption.h>, and recompile the library.
|
2001-12-20 22:22:02 +01:00
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
Additionally, define the _environment_ variable FT_DEBUG_MEMORY
|
|
|
|
|
and run any program using FreeType. When the library is exited,
|
|
|
|
|
a summary of memory footprints and possible leaks will be
|
|
|
|
|
displayed.
|
2001-12-20 22:22:02 +01:00
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
This works transparently with _any_ program that uses FreeType.
|
|
|
|
|
However, you will need a lot of memory to use this (allocated
|
|
|
|
|
blocks are never released to the heap to detect double deletes
|
|
|
|
|
easily).

III. MISCELLANEOUS
|
|
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
- We are aware of subtle differences between the output of
|
|
|
|
|
FreeType versions 1 and 2 when it comes to monochrome
|
|
|
|
|
TrueType-hinted glyphs. These are most probably due to small
|
|
|
|
|
differences in the monochrome rasterizers and will be worked out
|
|
|
|
|
in an upcoming release.
|
2001-12-20 22:22:02 +01:00
|
|
|
|
2007-01-09 11:37:36 +01:00
|
|
|
- We have decided to fork the sources in a `stable' branch, and an
|
|
|
|
|
`unstable' one, since FreeType is becoming a critical component
|
2003-09-12 21:38:13 +02:00
|
|
|
of many Unix systems.
|
2002-02-01 02:20:11 +01:00
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
The next bug-fix releases of the library will be named 2.0.7,
|
2007-01-09 11:37:36 +01:00
|
|
|
2.0.8, etc., while the `2.1' branch will contain a version of
|
2003-09-12 21:38:13 +02:00
|
|
|
the sources where we will start major reworking of the library's
|
|
|
|
|
internals, in order to produce FreeType 2.2.0 (or even 3.0) in a
|
|
|
|
|
more distant future.
|
2002-02-01 02:20:11 +01:00
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
We also hope that this scheme will allow much more frequent
|
|
|
|
|
releases than in the past.

|
|

|
2003-09-12 21:38:13 +02:00

NOTE THAT 2.0.5 DOES NOT CONTAIN THE POSTSCRIPT HINTER. THIS MODULE
|
|

|
|
WILL BE PART OF THE NEXT RELEASE (EITHER 2.0.6 or 2.1)

2007-01-09 11:37:36 +01:00

|
|
- Fixed a bug that made certain glyphs, like `Cacute', `cacute' and
|
|
|
|
|
`lslash' unavailable from Unicode charmaps of Postscript fonts.
|
2003-09-12 21:38:13 +02:00
|
|
|
This prevented the correct display of Polish text, for example.

|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
- The kerning table of Type 1 fonts was loaded by FreeType, when its
|
|
|
|
|
AFM file was attached to its face, but the
|
|
|
|
|
FT_FACE_FLAG_HAS_KERNING bit flags was not set correctly,
|
|
|
|
|
preventing FT_Get_Kerning to return meaningful values.

|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
- Improved SFNT (TrueType & OpenType) charmap support. Slightly
|
|
|
|
|
better performance, as well as support for the new formats defined
|
|
|
|
|
by the OpenType 1.3 specification (8, 10, and 12)
|
Fixed a bug in `glnames.py' that prevented it from generating
correct glyph names tables. This resulted in the unavailability of
certain glyphs like `Cacute', `cacute' and `lslash' in Unicode
charmaps, even if these were present in the font (causing problems
for Polish users).

|
|
|
|
|
possibly memory leaks) with Postscript fonts (in

the font transformation set through FT_Set_Transform was applied
|
|
|
|
|
twice to auto-hinted glyphs, resulting in incorrectly rotated text

output.

- A small memory leak that happened when opening 0-sized files
|
|
|
|
|
(duh!) have been fixed.
|
Fixed a bug in `glnames.py' that prevented it from generating
correct glyph names tables. This resulted in the unavailability of
certain glyphs like `Cacute', `cacute' and `lslash' in Unicode
charmaps, even if these were present in the font (causing problems
for Polish users).
* src/tools/glnames.py (mac_standard_names): Fixed.
(t1_standard_strings): Some fixes and renamed to ...
(sid_standard_names): This.
(t1_expert_encoding): Fixed.
(the_adobe_glyph_list): Renamed to ...
(adobe_glyph_names): This.
(the_adobe_glyphs): Renamed to ...
(adobe_glyph_values): This.
(dump_mac_indices, dump_glyph_list, dump_unicode_values, main):
Updated.
* src/psnames/pstables.h: Regenerated.
* src/psnames/psmodule.c (PS_Unicode_Value): Fix offset.
Fix return value.
Use `sid_standard_table' and `ps_names_to_unicode' instead of
`t1_standard_glyphs' and `names_to_unicode'.
(PS_Macintosh_Name): Use `ps_glyph_names' instead of
`standard_glyph_names'.
(PS_Standard_Strings): Use `sid_standard_names' instead of
`t1_standard_glyphs'.
* doc/BUGS, doc/TODO: New documents.
* src/cache/ftlru.c (FT_Lru_Lookup_Node): Fixed a bug that prevented
correct LRU behaviour.
setjmp() and longjmp() are now used for rollback (i.e. when memory
pool overflow occurs).
Function names are now all uniformly prefixed with `gray_'.
* src/smooth/ftgrays.c: Include <setjmp.h>.
(ErrRaster_MemoryOverflow): New macro.
(TArea): New type to store area values in each cell (using `int' was
too small on 16-bit systems). <limits.h> is included to properly
get the needed data type.
(TCell, TRaster): Use it.
(TRaster): New element `jump_buffer'.
(gray_compute_cbox): Use `RAS_ARG' as the only parameter and get
`outline' from it.

- Fixed bezier stack depth bug in the routines provided by the
|
|
|

- The outline bounding box code has been rewritten to use direct
|
|
|
|
|
computations, instead of bezier sub-division, to compute the
|
|
|
|
|
exact bounding box of glyphs. This is slightly slower but more
|
|
|
|
|
accurate.

2001-04-02 23:30:06 +02:00
|
|
|
avoid legal problems with the Apple patents. It seems that we
|
|
|
|
|
mistakenly turned this option on in previous releases of the
|
|
|
|
|
build.
|
2001-03-23 13:28:59 +01:00
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
Note that if you want to use the bytecode interpreter in order
|
|
|
|
|
to get high-quality TrueType rendering, you will need to toggle
|
|
|
|
|
by hand the definition of the
|
|
|
|
|
TT_CONFIG_OPTION_BYTECODE_INTERPRETER macro in the file
|
2007-01-09 11:37:36 +01:00
|
|
|
`include/freetype/config/ftoption.h'.
|
2001-04-02 23:30:06 +02:00
|
|
|
|
|
|
|
|
- The CFF driver has been improved by Tom Kacvinsky and Sander van
|
|
|
|
|
der Wal:
|
|
|
|
|
|
2007-01-09 11:37:36 +01:00
|
|
|
* Support for `seac' emulation.
|
|
|
|
|
* Support for `dotsection'.
|
2001-04-02 23:30:06 +02:00
|
|
|
* Support for retrieving glyph names through
|
2007-01-09 11:37:36 +01:00
|
|
|
`FT_Get_Glyph_Name'.
|
2001-03-23 13:28:59 +01:00
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
The first two items are necessary to correctly a large number of
|
|
|
|
|
Type 1 fonts converted to the CFF formats by Adobe Acrobat.
|
2001-03-23 13:28:59 +01:00
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
- The Type 1 driver was also improved by Tom & others:
|
2001-03-23 13:28:59 +01:00
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
* Better EM size computation.
|
|
|
|
|
* Better support for synthetic (transformed) fonts.
|
|
|
|
|
* The Type 1 driver returns the charstrings corresponding to
|
2007-01-09 11:37:36 +01:00
|
|
|
each glyph in the `glyph->control_data' field after a call to
|
|
|
|
|
`FT_Load_Glyph' (thanks Ha Shao).
|
2001-03-23 13:28:59 +01:00
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
- Various other bugfixes, including the following:
|
2001-03-23 13:28:59 +01:00
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
* Fixed a nasty memory leak in the Type 1 driver.
|
|
|
|
|
* The autohinter and the pcf driver used static writable data
|
|
|
|
|
when they shouldn't.
|
|
|
|
|
* Many casts were added to make the code more 64-bits safe. It
|
|
|
|
|
also now compiles on Windows XP 64-bits without warnings.
|
2007-01-09 11:37:36 +01:00
|
|
|
* Some incorrect writable statics were removed in the `autohint'
|
|
|
|
|
and `pcf' drivers. FreeType 2 now compiles on Epoc again.

II. CHANGES TO THE HIGH-LEVEL API
|
|
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
- The library header files inclusion scheme has been changed. The
|
|
|
|
|
old scheme looked like:
|
2001-03-23 19:09:09 +01:00
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
#include <freetype/freetype.h>
|
|
|
|
|
#include <freetype/ftglyph.h>
|
|
|
|
|
#include <freetype/ftcache.h>
|
|
|
|
|
#include <freetype/cache/ftimage.h>
|
2001-03-23 19:09:09 +01:00
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
Now you should use:
|
2001-03-23 13:28:59 +01:00
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
#include <ft2build.h>
|
|
|
|
|
#include FT_FREETYPE_H
|
|
|
|
|
#include FT_GLYPH_H
|
|
|
|
|
#include FT_CACHE_H
|
|
|
|
|
#include FT_CACHE_IMAGE_H
|
2001-03-23 13:28:59 +01:00
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
NOTE THAT THE OLD INCLUSION SCHEME WILL STILL WORK WITH THIS
|
|
|
|
|
RELEASE. HOWEVER, WE DO NOT GUARANTEE THAT THIS WILL STILL BE
|
|
|
|
|
TRUE IN THE NEXT ONE (A.K.A. FREETYPE 2.1).
|
2001-03-23 13:28:59 +01:00
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
The file <ft2build.h> is used to define the header filename
|
|
|
|
|
macros. The complete and commented list of macros is available
|
2007-01-09 11:37:36 +01:00
|
|
|
in the API reference under the section name `Header File Macros'
|
2001-04-02 23:30:06 +02:00
|
|
|
in Chapter I.
|
2000-12-01 19:55:22 +01:00
|
|
|
|
2001-04-02 23:30:06 +02:00

|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
- Many, many comments have been added to the public source file in
|
|
|
|
|
order to automatically generate the API Reference through the
|
2007-01-09 11:37:36 +01:00
|
|
|
`docmaker.py' Python script.
|
2000-12-01 19:55:22 +01:00
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
The latter has been updated to support the grouping of sections
|
|
|
|
|
in chapters and better index sort. See:

III. CHANGES TO THE BUILD PROCESS
|
2000-11-09 20:10:22 +01:00
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
- If you are not building FreeType 2 with its own build system
|
|
|
|
|
(but with your own Makefiles or project files), you will need to
|
|
|
|
|
be aware that the build process has changed a little bit.
|
2000-11-09 20:10:22 +01:00
|
|
|
|
2007-01-09 11:37:36 +01:00
|
|
|
You don't need to put the `src' directory in the include path
|
2001-04-02 23:30:06 +02:00
|
|
|
when compiling any FT2 component. Instead, simply put the
|
|
|
|
|
component's directory in the current include path.
|
2000-11-09 20:10:22 +01:00
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
So, if you were doing something like:
|
2000-11-09 20:10:22 +01:00
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
cc -c -Iinclude -Isrc src/base/ftbase.c
|
2000-11-09 20:10:22 +01:00
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
change the line to:
|
2000-11-09 20:10:22 +01:00
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
cc -c -Iinclude -Isrc/base src/base/ftbase.c
|
2000-10-28 19:10:06 +02:00
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
If you were doing something like:
|
2000-09-16 00:42:06 +02:00
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
cd src/base
|
|
|
|
|
cc -c -I../../include -I.. ftbase.c
|
2000-08-24 00:47:44 +02:00
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
change it to:
|
2000-08-23 23:11:13 +02:00
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
cd src/base
|
|
|
|
|
cc -c -I../../include ftbase.c

CHANGES BETWEEN 2.0.1 and 2.0
|
2000-07-27 23:48:48 +02:00
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
2.0.1 introduces a few changes:
|
2000-10-31 21:42:18 +01:00
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
- Fixed many bugs related to the support of CFF / OpenType fonts.
|
|
|
|
|
These formats are now much better supported though there is
|
|
|
|
|
still work planned to deal with charset tables and PDF-embedded
|
2007-01-09 11:37:36 +01:00
|
|
|
CFF files that use the old `seac' command.
|
2000-07-27 23:40:22 +02:00
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
- The library could not be compiled in debug mode with a very
|
|
|
|
|
small number of C compilers whose pre-processors didn't
|
2007-01-09 11:37:36 +01:00
|
|
|
implement the `##' directive correctly (i.e. per se the ANSI C
|
2001-04-02 23:30:06 +02:00
|
|
|
specification!) An elegant fix was found.
|
2000-07-27 23:40:22 +02:00
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
- Added support for the free Borland command-line C++ Builder
|
2007-01-09 11:37:36 +01:00
|
|
|
compiler. Use `make setup bcc32'. Also fixed a few source
|
2001-04-02 23:30:06 +02:00
|
|
|
lines that generated new warnings with BCC32.
|
2000-07-27 23:40:22 +02:00
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
- Fixed a bug in FT_Outline_Get_BBox when computing the extrema of
|
|
|
|
|
a conic Bezier arc.
|
2000-10-31 21:42:18 +01:00
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
- Updated the INSTALL file to add IDE compilation.
|
2000-07-26 21:13:51 +02:00
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
- Other minor bug fixes, from invalid Type 1 style flags to
|
|
|
|
|
correct support of synthetic (obliqued) fonts in the
|
|
|
|
|
auto-hinter, better support for embedded bitmaps in a SFNT font.
|
2000-10-31 21:42:18 +01:00
|
|
|
|
2007-01-09 11:37:36 +01:00
|
|
|
- Fixed some problems with `freetype-config'.
|
2000-07-26 21:04:08 +02:00
|
|
|
|
2007-01-09 11:37:36 +01:00
|
|
|
Finally, the `standard' scheme for including FreeType headers is now
|
2001-04-02 23:30:06 +02:00
|
|
|
gradually changing, but this will be explained in a later release
|
|
|
|
|
(probably 2.0.2).
|
2000-07-12 18:57:37 +02:00

2001-04-02 23:30:06 +02:00

And very special thanks to Tom Kacvinsky and YAMANO-UCHI Hidetoshi
|
|
|
|
|
for their contributions!

CHANGES BETWEEN beta8 and 2.0
|
2000-10-31 21:42:18 +01:00
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
- Changed the default installation path for public headers from
|
2007-01-09 11:37:36 +01:00
|
|
|
`include/freetype' to `include/freetype2'.
|
2000-10-31 21:42:18 +01:00
|
|
|
|
2007-01-09 11:37:36 +01:00
|
|
|
Also added a new `freetype-config' that is automatically generated
|
2001-04-02 23:30:06 +02:00
|
|
|
and installed on Unix and Cygwin systems. The script itself is
|
|
|
|
|
used to retrieve the current install path, C compilation flags as
|
|
|
|
|
well as linker flags.
|
2000-07-07 21:47:34 +02:00
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
- Fixed several small bugs:
|
2000-07-07 21:47:34 +02:00
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
* Incorrect max advance width for fixed-pitch Type 1 fonts.
|
|
|
|
|
* Incorrect glyph names for certain TrueType fonts.
|
|
|
|
|
* The glyph advance was not copied when FT_Glyph_To_Bitmap was
|
|
|
|
|
called.
|
2007-01-17 13:45:26 +01:00
|
|
|
* The linearHoriAdvance and linearVertAdvance fields were not
|
2001-04-02 23:30:06 +02:00
|
|
|
correctly returned for glyphs processed by the auto-hinter.
|
2007-01-09 11:37:36 +01:00
|
|
|
* `type1z' renamed back to `type1'; the old `type1' module has
|
2001-04-02 23:30:06 +02:00
|
|
|
been removed.
|
2000-10-31 21:42:18 +01:00
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
- Revamped the build system to make it a lot more generic. This
|
|
|
|
|
will allow us to re-use nearly un-modified in lots of other
|
|
|
|
|
projects (including FreeType Layout).
|
2000-10-31 21:42:18 +01:00
|
|
|
|
2007-01-09 11:37:36 +01:00
|
|
|
- Changed `cid' to use `psaux' too.
|
2000-10-31 21:42:18 +01:00
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
- Added the cache sub-system. See <freetype/ftcache.h> as well as
|
2007-01-09 11:37:36 +01:00
|
|
|
the sources in `src/cache'. Note that it compiles but is still
|
2001-04-02 23:30:06 +02:00
|
|
|
untested for now.
|
2000-07-01 01:38:23 +02:00
|
|
|
|
2007-01-09 11:37:36 +01:00
|
|
|
- Updated `docs/docmaker.py', a draft API reference is available at
|
2018-12-25 22:44:05 +01:00
|
|
|
https://web.archive.org/web/20001215173400/http://www.freetype.org:80/ft2api.html.
|
2000-07-01 01:38:23 +02:00
|
|
|
|
2007-01-09 11:37:36 +01:00
|
|
|
- Changed `type1' to use `psaux'.
|
2000-10-31 21:42:18 +01:00
|
|
|
|
2007-01-09 11:37:36 +01:00
|
|
|
- Created a new module named `psaux' to hold the Type 1 & Type 2
|
|
|
|
|
parsing routines. It should be used by `type1', `cid', and `cff'
|
2001-04-02 23:30:06 +02:00
|
|
|
in the future.
|
2000-10-31 21:42:18 +01:00
|
|
|
|
2007-01-09 11:37:36 +01:00
|
|
|
- Fixed an important bug in `FT_Glyph_Get_CBox'.

- Fixed some compiler warnings that happened since the TrueType
|
|
|
|
|
bytecode decoder was deactivated by default.

|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
* The memory manager (16 bytes) isn't released in
|
|
|
|
|
FT_Done_FreeType!
|
|
|
|
|
* Using custom input streams, the copy of the original stream was
|
|
|
|
|
never released.

- Fixed the auto-hinter by performing automatic computation of the
|
2007-01-09 11:37:36 +01:00
|
|
|
`filling direction' of each glyph. This is done through a simple
|
2001-04-02 23:30:06 +02:00
|
|
|
and fast approximation, and seems to work (problems spotted by
|
|
|
|
|
Werner though). The Arphic fonts are a lot nicer though there are
|
|
|
|
|
still a lot of things to do to handle Asian fonts correctly.

BETA-8 (RELEASE CANDIDATE) CHANGES
|
2000-06-28 01:32:27 +02:00
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
- Deactivated the TrueType bytecode interpreter by default.
|
2000-10-31 21:42:18 +01:00
|
|
|
|
2007-01-09 11:37:36 +01:00
|
|
|
- Deactivated the `src/type1' font driver. Now `src/type1z' is used
|
2001-04-02 23:30:06 +02:00
|
|
|
by default.
|
2000-10-31 21:42:18 +01:00
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
- Updates to the build system. We now compile the library correctly
|
2007-01-09 11:37:36 +01:00
|
|
|
under Unix system through `configure' which is automatically
|
|
|
|
|
called on the first `make' invocation.
|
2000-07-01 01:38:23 +02:00
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
- Added the auto-hinting module! Fixing some bugs here and there.
|
2000-07-01 01:38:23 +02:00
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
- Found some bugs in the composite loader (seac) of the Type1-based
|
|
|
|
|
font drivers.
|
2000-07-01 01:38:23 +02:00
|
|
|
|
2007-01-09 11:37:36 +01:00
|
|
|
- Renamed the directory `freetype2/config' to `freetype2/builds' and
|
2001-04-02 23:30:06 +02:00
|
|
|
updated all relevant files.
|
2000-10-31 21:42:18 +01:00
|
|
|
|
2007-01-09 11:37:36 +01:00
|
|
|
- Found a memory leak in the `type1' driver.
|
2000-10-31 21:42:18 +01:00
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
- Incorporated Tom's patches to support flex operators correctly in
|
|
|
|
|
OpenType/CFF fonts. Now all I need is to support pure CFF and CEF
|
|
|
|
|
fonts to be done with this driver :-)
|
2000-10-31 21:42:18 +01:00
|
|
|
|
2007-01-09 11:37:36 +01:00
|
|
|
- Added the Windows FNT/FON driver in `src/winfonts'. For now, it
|
|
|
|
|
always `simulates' a Unicode charmap, so it shouldn't be
|
2001-04-02 23:30:06 +02:00
|
|
|
considered completed right now.
|
2000-07-01 01:38:23 +02:00
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
It is there to be more a proof of concept than anything else
|
|
|
|
|
anyway. The driver is a single C source file, that compiles to 3
|
|
|
|
|
Kb of code.
|
2000-07-01 01:38:23 +02:00
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
I'm still working on the PCF/BDF drivers, but I'm too lazy to
|
|
|
|
|
finish them now.

- CHANGES TO THE HIGH-LEVEL API
|
2000-10-31 21:42:18 +01:00
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
* FT_Get_Kerning has a new parameter that allows you to select the
|
|
|
|
|
coordinates of the kerning vector (font units, scaled, scaled +
|
|
|
|
|
grid-fitted).
|
|
|
|
|
* The outline functions are now in <freetype/ftoutln.h> and not
|
|
|
|
|
part of <freetype/freetype.h> anymore.
|
|
|
|
|
* <freetype/ftmodule.h> now contains declarations for
|
|
|
|
|
FT_New_Library, FT_Done_Library, FT_Add_Default_Modules.
|
2007-01-09 11:37:36 +01:00
|
|
|
* The so-called convenience functions have moved from `ftoutln.c'
|
|
|
|
|
to `ftglyph.c', and are thus available with this optional
|
2001-04-02 23:30:06 +02:00
|
|
|
component of the library. They are declared in
|
|
|
|
|
<freetype/ftglyph.h> now.
|
|
|
|
|
* Anti-aliased rendering is now the default for FT_Render_Glyph
|
|
|
|
|
(i.e. corresponds to render_mode == 0 == ft_render_mode_normal).
|
|
|
|
|
To generate a monochrome bitmap, use ft_render_mode_mono, or the
|
|
|
|
|
FT_LOAD_MONOCHROME flag in FT_Load_Glyph/FT_Load_Char.
|
|
|
|
|
FT_LOAD_ANTI_ALIAS is still defined, but values to 0.
|
|
|
|
|
* <freetype/freetype.h> now include <freetype/config/ftconfig.h>,
|
|
|
|
|
solving a few headaches :-)
|
2007-01-09 11:37:36 +01:00
|
|
|
* The type FT_GlyphSlotRec has now a `library' field.
|

- CHANGES TO THE `ftglyph.h' API
|
2000-10-31 21:42:18 +01:00
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
This API has been severely modified in order to make it simpler,
|
|
|
|
|
clearer, and more efficient. It certainly now looks like a real
|
2007-01-09 11:37:36 +01:00
|
|
|
`glyph factory' object, and allows client applications to manage
|
2001-04-02 23:30:06 +02:00
|
|
|
(i.e. transform, bbox and render) glyph images without ever
|
|
|
|
|
knowing their original format.
|
2000-10-31 21:42:18 +01:00
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
- Added support for CID-keyed fonts to the CFF driver. Maybe
|
|
|
|
|
support for pure CFF + CEF fonts should come in?
|
2000-10-31 21:42:18 +01:00
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
- Cleaned up source code in order to avoid two functions with the
|
2007-01-09 11:37:36 +01:00
|
|
|
same name. Also changed the names of the files in `type1z' from
|
|
|
|
|
`t1XXXX' to `z1XXXX' in order to avoid any conflicts.
|
2000-10-31 21:42:18 +01:00
|
|
|
|
2007-01-09 11:37:36 +01:00
|
|
|
`make multi' now works well :-)
|
2000-10-31 21:42:18 +01:00
|
|
|
|
2007-01-09 11:37:36 +01:00
|
|
|
Also removed the use of `cidafm' for now, even if the source files
|
2001-04-02 23:30:06 +02:00
|
|
|
are still there. This functionality will certainly go into a
|
|
|
|
|
specific module.
|
2000-10-31 21:42:18 +01:00

- ADDED SUPPORT FOR THE AUTO-HINTER
|
2000-10-31 21:42:18 +01:00
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
It works :-) I have a demo program which simply is a copy of
|
2007-01-09 11:37:36 +01:00
|
|
|
`ftview' that does a `FT_Add_Module(library,
|
2001-04-02 23:30:06 +02:00
|
|
|
&autohinter_module_class)' after library initialization, and Type
|
|
|
|
|
1 & OpenType/CFF fonts are now hinted.
|
2000-06-28 01:32:27 +02:00
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
CID fonts are not hinted, as they include no charmap and the
|
2007-01-09 11:37:36 +01:00
|
|
|
auto-hinter doesn't include `generic' global metrics computations
|
2001-04-02 23:30:06 +02:00
|
|
|
yet.
|
2000-10-31 21:42:18 +01:00
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
Now, I need to release this thing to the FreeType 2 source.

- CHANGES TO THE RENDERER MODULES
|
2000-10-31 21:42:18 +01:00
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
The monochrome and smooth renderers are now in two distinct
|
2007-01-09 11:37:36 +01:00
|
|
|
directories, namely `src/raster1' and `src/smooth'. Note that the
|
|
|
|
|
old `src/renderer' is now gone.
|
- MAJOR INTERNAL REDESIGN:
A lot of internal modifications have been performed lately on the
source in order to provide the following enhancements:
- more generic module support:
The FT_Module type is now defined to represent a handle to a given
module. The file <freetype/ftmodule.h> contains the FT_Module_Class
definition, as well as the module-loading public API
The FT_Driver type is still defined, and still represents a pointer
to a font driver. Note that FT_Add_Driver is replaced by FT_Add_Module,
FT_Get_Driver by FT_Get_Module, etc..
- support for generic glyph image types:
The FT_Renderer type is a pointer to a module used to perform various
operations on glyph image.
Each renderer is capable of handling images in a single format
(e.g. ft_glyph_format_outline). Its functions are used to:
- transform an glyph image
- render a glyph image into a bitmap
- return the control box (dimensions) of a given glyph image
The scan converters "ftraster.c" and "ftgrays.c" have been moved
to the new directory "src/renderer", and are used to provide two
default renderer modules.
One corresponds to the "standard" scan-converter, the other to the
"smooth" one.
The current renderer can be set through the new function
FT_Set_Renderer.
The old raster-related function FT_Set_Raster, FT_Get_Raster and
FT_Set_Raster_Mode have now disappeared, in favor of the new:
FT_Get_Renderer
FT_Set_Renderer
see the file <freetype/ftrender.h> for more details..
These changes were necessary to properly support different scalable
formats in the future, like bi-color glyphs, etc..
- glyph loader object:
A new internal object, called a 'glyph loader' has been introduced
in the base layer. It is used by all scalable format font drivers
to load glyphs and composites.
This object has been created to reduce the code size of each driver,
as each one of them basically re-implemented its functionality.
See <freetype/internal/ftobjs.h> and the FT_GlyphLoader type for
more information..
- FT_GlyphSlot had new fields:
In order to support extended features (see below), the FT_GlyphSlot
structure has a few new fields:
linearHoriAdvance: this field gives the linearly scaled (i.e.
scaled but unhinted) advance width for the glyph,
expressed as a 16.16 fixed pixel value. This
is useful to perform WYSIWYG text.
linearVertAdvance: this field gives the linearly scaled advance
height for the glyph (relevant in vertical glyph
layouts only). This is useful to perform
WYSIWYG text.
Note that the two above field replace the removed "metrics2" field
in the glyph slot.
advance: this field is a vector that gives the transformed
advance for the glyph. By default, it corresponds
to the advance width, unless FT_LOAD_VERTICAL_LAYOUT
was specified when calling FT_Load_Glyph or FT_Load_Char
bitmap_left: this field gives the distance in integer pixels from
the current pen position to the left-most pixel of
a glyph image WHEN IT IS A BITMAP. It is only valid
when the "format" field is set to
"ft_glyph_format_bitmap", for example, after calling
the new function FT_Render_Glyph.
bitmap_top: this field gives the distance in integer pixels from
the current pen position (located on the baseline) to
the top-most pixel of the glyph image WHEN IT IS A
BITMAP. Positive values correspond to upwards Y.
loader: this is a new private field for the glyph slot. Client
applications should not touch it..
- support for transforms and direct rendering in FT_Load_Glyph:
Most of the functionality found in <freetype/ftglyph.h> has been
moved to the core library. Hence, the following:
- a transform can be specified for a face through FT_Set_Transform.
this transform is applied by FT_Load_Glyph to scalable glyph images
(i.e. NOT TO BITMAPS) before the function returns, unless the
bit flag FT_LOAD_IGNORE_TRANSFORM was set in the load flags..
- once a glyph image has been loaded, it can be directly converted to
a bitmap by using the new FT_Render_Glyph function. Note that this
function takes the glyph image from the glyph slot, and converts
it to a bitmap whose properties are returned in "face.glyph.bitmap",
"face.glyph.bitmap_left" and "face.glyph.bitmap_top". The original
native image might be lost after the conversion.
- when using the new bit flag FT_LOAD_RENDER, the FT_Load_Glyph
and FT_Load_Char functions will call FT_Render_Glyph automatically
when needed.

I ditched the 5-gray-levels renderers. Basically, it involved a
|
|
|
|
|
simple #define toggle in 'src/raster1/ftraster.c'.

FT_Render_Glyph, FT_Outline_Render & FT_Outline_Get_Bitmap now
|
|
|
|
|
select the best renderer available, depending on render mode. If
|
|
|
|
|
the current renderer for a given glyph image format isn't capable
|
|
|
|
|
of supporting the render mode, another one will be found in the
|
|
|
|
|
library's list. This means that client applications do not need
|
|
|
|
|
to switch or set the renderers themselves (as in the latest
|
|
|
|
|
change), they'll get what they want automatically. At last.

see the file <freetype/ftrender.h> for more details..
These changes were necessary to properly support different scalable
formats in the future, like bi-color glyphs, etc..
- glyph loader object:
A new internal object, called a 'glyph loader' has been introduced
in the base layer. It is used by all scalable format font drivers
to load glyphs and composites.
This object has been created to reduce the code size of each driver,
as each one of them basically re-implemented its functionality.
See <freetype/internal/ftobjs.h> and the FT_GlyphLoader type for
more information..
- FT_GlyphSlot had new fields:
In order to support extended features (see below), the FT_GlyphSlot
structure has a few new fields:
linearHoriAdvance: this field gives the linearly scaled (i.e.
scaled but unhinted) advance width for the glyph,
expressed as a 16.16 fixed pixel value. This
is useful to perform WYSIWYG text.
linearVertAdvance: this field gives the linearly scaled advance
height for the glyph (relevant in vertical glyph
layouts only). This is useful to perform
WYSIWYG text.
Note that the two above field replace the removed "metrics2" field
in the glyph slot.
advance: this field is a vector that gives the transformed
advance for the glyph. By default, it corresponds
to the advance width, unless FT_LOAD_VERTICAL_LAYOUT
was specified when calling FT_Load_Glyph or FT_Load_Char
bitmap_left: this field gives the distance in integer pixels from
the current pen position to the left-most pixel of
a glyph image WHEN IT IS A BITMAP. It is only valid
when the "format" field is set to
"ft_glyph_format_bitmap", for example, after calling
the new function FT_Render_Glyph.
bitmap_top: this field gives the distance in integer pixels from
the current pen position (located on the baseline) to
the top-most pixel of the glyph image WHEN IT IS A
BITMAP. Positive values correspond to upwards Y.
loader: this is a new private field for the glyph slot. Client
applications should not touch it..
- support for transforms and direct rendering in FT_Load_Glyph:
Most of the functionality found in <freetype/ftglyph.h> has been
moved to the core library. Hence, the following:
- a transform can be specified for a face through FT_Set_Transform.
this transform is applied by FT_Load_Glyph to scalable glyph images
(i.e. NOT TO BITMAPS) before the function returns, unless the
bit flag FT_LOAD_IGNORE_TRANSFORM was set in the load flags..
- once a glyph image has been loaded, it can be directly converted to
a bitmap by using the new FT_Render_Glyph function. Note that this
function takes the glyph image from the glyph slot, and converts
it to a bitmap whose properties are returned in "face.glyph.bitmap",
"face.glyph.bitmap_left" and "face.glyph.bitmap_top". The original
native image might be lost after the conversion.
- when using the new bit flag FT_LOAD_RENDER, the FT_Load_Glyph
and FT_Load_Char functions will call FT_Render_Glyph automatically
when needed.

- MAJOR INTERNAL REDESIGN:
A lot of internal modifications have been performed lately on the
source in order to provide the following enhancements:
- more generic module support:
The FT_Module type is now defined to represent a handle to a given
module. The file <freetype/ftmodule.h> contains the FT_Module_Class
definition, as well as the module-loading public API
The FT_Driver type is still defined, and still represents a pointer
to a font driver. Note that FT_Add_Driver is replaced by FT_Add_Module,
FT_Get_Driver by FT_Get_Module, etc..
- support for generic glyph image types:
The FT_Renderer type is a pointer to a module used to perform various
operations on glyph image.
Each renderer is capable of handling images in a single format
(e.g. ft_glyph_format_outline). Its functions are used to:
- transform an glyph image
- render a glyph image into a bitmap
- return the control box (dimensions) of a given glyph image
The scan converters "ftraster.c" and "ftgrays.c" have been moved
to the new directory "src/renderer", and are used to provide two
default renderer modules.
One corresponds to the "standard" scan-converter, the other to the
"smooth" one.
The current renderer can be set through the new function
FT_Set_Renderer.
The old raster-related function FT_Set_Raster, FT_Get_Raster and
FT_Set_Raster_Mode have now disappeared, in favor of the new:
FT_Get_Renderer
FT_Set_Renderer

- MAJOR INTERNAL REDESIGN:
A lot of internal modifications have been performed lately on the
source in order to provide the following enhancements:
- more generic module support:
The FT_Module type is now defined to represent a handle to a given
module. The file <freetype/ftmodule.h> contains the FT_Module_Class
definition, as well as the module-loading public API
The FT_Driver type is still defined, and still represents a pointer
to a font driver. Note that FT_Add_Driver is replaced by FT_Add_Module,
FT_Get_Driver by FT_Get_Module, etc..
- support for generic glyph image types:
The FT_Renderer type is a pointer to a module used to perform various
operations on glyph image.
Each renderer is capable of handling images in a single format
(e.g. ft_glyph_format_outline). Its functions are used to:
- transform an glyph image
- render a glyph image into a bitmap
- return the control box (dimensions) of a given glyph image
The scan converters "ftraster.c" and "ftgrays.c" have been moved
to the new directory "src/renderer", and are used to provide two
default renderer modules.
One corresponds to the "standard" scan-converter, the other to the
"smooth" one.
The current renderer can be set through the new function
FT_Set_Renderer.
The old raster-related function FT_Set_Raster, FT_Get_Raster and
FT_Set_Raster_Mode have now disappeared, in favor of the new:
FT_Get_Renderer
FT_Set_Renderer
see the file <freetype/ftrender.h> for more details..
These changes were necessary to properly support different scalable
formats in the future, like bi-color glyphs, etc..
- glyph loader object:
A new internal object, called a 'glyph loader' has been introduced
in the base layer. It is used by all scalable format font drivers
to load glyphs and composites.
This object has been created to reduce the code size of each driver,
as each one of them basically re-implemented its functionality.
See <freetype/internal/ftobjs.h> and the FT_GlyphLoader type for
more information..
- FT_GlyphSlot had new fields:
In order to support extended features (see below), the FT_GlyphSlot
structure has a few new fields:
linearHoriAdvance: this field gives the linearly scaled (i.e.
scaled but unhinted) advance width for the glyph,
expressed as a 16.16 fixed pixel value. This
is useful to perform WYSIWYG text.
linearVertAdvance: this field gives the linearly scaled advance
height for the glyph (relevant in vertical glyph
layouts only). This is useful to perform
WYSIWYG text.
Note that the two above field replace the removed "metrics2" field
in the glyph slot.
advance: this field is a vector that gives the transformed
advance for the glyph. By default, it corresponds
to the advance width, unless FT_LOAD_VERTICAL_LAYOUT
was specified when calling FT_Load_Glyph or FT_Load_Char
bitmap_left: this field gives the distance in integer pixels from
the current pen position to the left-most pixel of
a glyph image WHEN IT IS A BITMAP. It is only valid
when the "format" field is set to
"ft_glyph_format_bitmap", for example, after calling
the new function FT_Render_Glyph.
bitmap_top: this field gives the distance in integer pixels from
the current pen position (located on the baseline) to
the top-most pixel of the glyph image WHEN IT IS A
BITMAP. Positive values correspond to upwards Y.
loader: this is a new private field for the glyph slot. Client
applications should not touch it..
- support for transforms and direct rendering in FT_Load_Glyph:
Most of the functionality found in <freetype/ftglyph.h> has been
moved to the core library. Hence, the following:
- a transform can be specified for a face through FT_Set_Transform.
this transform is applied by FT_Load_Glyph to scalable glyph images
(i.e. NOT TO BITMAPS) before the function returns, unless the
bit flag FT_LOAD_IGNORE_TRANSFORM was set in the load flags..
- once a glyph image has been loaded, it can be directly converted to
a bitmap by using the new FT_Render_Glyph function. Note that this
function takes the glyph image from the glyph slot, and converts
it to a bitmap whose properties are returned in "face.glyph.bitmap",
"face.glyph.bitmap_left" and "face.glyph.bitmap_top". The original
native image might be lost after the conversion.
- when using the new bit flag FT_LOAD_RENDER, the FT_Load_Glyph
and FT_Load_Char functions will call FT_Render_Glyph automatically
when needed.

The FT_Renderer type is a pointer to a module used to perform various
operations on glyph image.
Each renderer is capable of handling images in a single format
(e.g. ft_glyph_format_outline). Its functions are used to:
- transform an glyph image
- render a glyph image into a bitmap
- return the control box (dimensions) of a given glyph image
The scan converters "ftraster.c" and "ftgrays.c" have been moved
to the new directory "src/renderer", and are used to provide two
default renderer modules.
One corresponds to the "standard" scan-converter, the other to the
"smooth" one.
The current renderer can be set through the new function
FT_Set_Renderer.
The old raster-related function FT_Set_Raster, FT_Get_Raster and
FT_Set_Raster_Mode have now disappeared, in favor of the new:
FT_Get_Renderer
FT_Set_Renderer
see the file <freetype/ftrender.h> for more details..
These changes were necessary to properly support different scalable
formats in the future, like bi-color glyphs, etc..
- glyph loader object:
A new internal object, called a 'glyph loader' has been introduced
in the base layer. It is used by all scalable format font drivers
to load glyphs and composites.
This object has been created to reduce the code size of each driver,
as each one of them basically re-implemented its functionality.
See <freetype/internal/ftobjs.h> and the FT_GlyphLoader type for
more information..
- FT_GlyphSlot had new fields:
In order to support extended features (see below), the FT_GlyphSlot
structure has a few new fields:
linearHoriAdvance: this field gives the linearly scaled (i.e.
scaled but unhinted) advance width for the glyph,
expressed as a 16.16 fixed pixel value. This
is useful to perform WYSIWYG text.
linearVertAdvance: this field gives the linearly scaled advance
height for the glyph (relevant in vertical glyph
layouts only). This is useful to perform
WYSIWYG text.
Note that the two above field replace the removed "metrics2" field
in the glyph slot.
advance: this field is a vector that gives the transformed
advance for the glyph. By default, it corresponds
to the advance width, unless FT_LOAD_VERTICAL_LAYOUT
was specified when calling FT_Load_Glyph or FT_Load_Char
bitmap_left: this field gives the distance in integer pixels from
the current pen position to the left-most pixel of
a glyph image WHEN IT IS A BITMAP. It is only valid
when the "format" field is set to
"ft_glyph_format_bitmap", for example, after calling
the new function FT_Render_Glyph.
bitmap_top: this field gives the distance in integer pixels from
the current pen position (located on the baseline) to
the top-most pixel of the glyph image WHEN IT IS A
BITMAP. Positive values correspond to upwards Y.
loader: this is a new private field for the glyph slot. Client
applications should not touch it..
- support for transforms and direct rendering in FT_Load_Glyph:
Most of the functionality found in <freetype/ftglyph.h> has been
moved to the core library. Hence, the following:
- a transform can be specified for a face through FT_Set_Transform.
this transform is applied by FT_Load_Glyph to scalable glyph images
(i.e. NOT TO BITMAPS) before the function returns, unless the
bit flag FT_LOAD_IGNORE_TRANSFORM was set in the load flags..
- once a glyph image has been loaded, it can be directly converted to
a bitmap by using the new FT_Render_Glyph function. Note that this
function takes the glyph image from the glyph slot, and converts
it to a bitmap whose properties are returned in "face.glyph.bitmap",
"face.glyph.bitmap_left" and "face.glyph.bitmap_top". The original
native image might be lost after the conversion.
- when using the new bit flag FT_LOAD_RENDER, the FT_Load_Glyph
and FT_Load_Char functions will call FT_Render_Glyph automatically
when needed.

- MAJOR INTERNAL REDESIGN:
A lot of internal modifications have been performed lately on the
source in order to provide the following enhancements:

module. The file <freetype/ftmodule.h> contains the FT_Module_Class
definition, as well as the module-loading public API

- MAJOR INTERNAL REDESIGN:
A lot of internal modifications have been performed lately on the
source in order to provide the following enhancements:
- more generic module support:
The FT_Module type is now defined to represent a handle to a given
module. The file <freetype/ftmodule.h> contains the FT_Module_Class
definition, as well as the module-loading public API
The FT_Driver type is still defined, and still represents a pointer
to a font driver. Note that FT_Add_Driver is replaced by FT_Add_Module,
FT_Get_Driver by FT_Get_Module, etc..
- support for generic glyph image types:
The FT_Renderer type is a pointer to a module used to perform various
operations on glyph image.
Each renderer is capable of handling images in a single format
(e.g. ft_glyph_format_outline). Its functions are used to:
- transform an glyph image
- render a glyph image into a bitmap
- return the control box (dimensions) of a given glyph image
The scan converters "ftraster.c" and "ftgrays.c" have been moved
to the new directory "src/renderer", and are used to provide two
default renderer modules.
One corresponds to the "standard" scan-converter, the other to the
"smooth" one.
The current renderer can be set through the new function
FT_Set_Renderer.
The old raster-related function FT_Set_Raster, FT_Get_Raster and
FT_Set_Raster_Mode have now disappeared, in favor of the new:
FT_Get_Renderer
FT_Set_Renderer
see the file <freetype/ftrender.h> for more details..
These changes were necessary to properly support different scalable
formats in the future, like bi-color glyphs, etc..
- glyph loader object:
A new internal object, called a 'glyph loader' has been introduced
in the base layer. It is used by all scalable format font drivers
to load glyphs and composites.
This object has been created to reduce the code size of each driver,
as each one of them basically re-implemented its functionality.
See <freetype/internal/ftobjs.h> and the FT_GlyphLoader type for
more information..
- FT_GlyphSlot had new fields:
In order to support extended features (see below), the FT_GlyphSlot
structure has a few new fields:
linearHoriAdvance: this field gives the linearly scaled (i.e.
scaled but unhinted) advance width for the glyph,
expressed as a 16.16 fixed pixel value. This
is useful to perform WYSIWYG text.
linearVertAdvance: this field gives the linearly scaled advance
height for the glyph (relevant in vertical glyph
layouts only). This is useful to perform
WYSIWYG text.
Note that the two above field replace the removed "metrics2" field
in the glyph slot.
advance: this field is a vector that gives the transformed
advance for the glyph. By default, it corresponds
to the advance width, unless FT_LOAD_VERTICAL_LAYOUT
was specified when calling FT_Load_Glyph or FT_Load_Char
bitmap_left: this field gives the distance in integer pixels from
the current pen position to the left-most pixel of
a glyph image WHEN IT IS A BITMAP. It is only valid
when the "format" field is set to
"ft_glyph_format_bitmap", for example, after calling
the new function FT_Render_Glyph.
bitmap_top: this field gives the distance in integer pixels from
the current pen position (located on the baseline) to
the top-most pixel of the glyph image WHEN IT IS A
BITMAP. Positive values correspond to upwards Y.
loader: this is a new private field for the glyph slot. Client
applications should not touch it..
- support for transforms and direct rendering in FT_Load_Glyph:
Most of the functionality found in <freetype/ftglyph.h> has been
moved to the core library. Hence, the following:
- a transform can be specified for a face through FT_Set_Transform.
this transform is applied by FT_Load_Glyph to scalable glyph images
(i.e. NOT TO BITMAPS) before the function returns, unless the
bit flag FT_LOAD_IGNORE_TRANSFORM was set in the load flags..
- once a glyph image has been loaded, it can be directly converted to
a bitmap by using the new FT_Render_Glyph function. Note that this
function takes the glyph image from the glyph slot, and converts
it to a bitmap whose properties are returned in "face.glyph.bitmap",
"face.glyph.bitmap_left" and "face.glyph.bitmap_top". The original
native image might be lost after the conversion.
- when using the new bit flag FT_LOAD_RENDER, the FT_Load_Glyph
and FT_Load_Char functions will call FT_Render_Glyph automatically
when needed.

- once a glyph image has been loaded, it can be directly converted to
a bitmap by using the new FT_Render_Glyph function. Note that this
function takes the glyph image from the glyph slot, and converts
it to a bitmap whose properties are returned in "face.glyph.bitmap",
"face.glyph.bitmap_left" and "face.glyph.bitmap_top". The original
native image might be lost after the conversion.
- when using the new bit flag FT_LOAD_RENDER, the FT_Load_Glyph
and FT_Load_Char functions will call FT_Render_Glyph automatically
when needed.

- MAJOR INTERNAL REDESIGN:
A lot of internal modifications have been performed lately on the
source in order to provide the following enhancements:
- more generic module support:
The FT_Module type is now defined to represent a handle to a given
module. The file <freetype/ftmodule.h> contains the FT_Module_Class
definition, as well as the module-loading public API
The FT_Driver type is still defined, and still represents a pointer
to a font driver. Note that FT_Add_Driver is replaced by FT_Add_Module,
FT_Get_Driver by FT_Get_Module, etc..
- support for generic glyph image types:
The FT_Renderer type is a pointer to a module used to perform various
operations on glyph image.
Each renderer is capable of handling images in a single format
(e.g. ft_glyph_format_outline). Its functions are used to:
- transform an glyph image
- render a glyph image into a bitmap
- return the control box (dimensions) of a given glyph image
The scan converters "ftraster.c" and "ftgrays.c" have been moved
to the new directory "src/renderer", and are used to provide two
default renderer modules.
One corresponds to the "standard" scan-converter, the other to the
"smooth" one.
The current renderer can be set through the new function
FT_Set_Renderer.
The old raster-related function FT_Set_Raster, FT_Get_Raster and
FT_Set_Raster_Mode have now disappeared, in favor of the new:
FT_Get_Renderer
FT_Set_Renderer
see the file <freetype/ftrender.h> for more details..
These changes were necessary to properly support different scalable
formats in the future, like bi-color glyphs, etc..
- glyph loader object:
A new internal object, called a 'glyph loader' has been introduced
in the base layer. It is used by all scalable format font drivers
to load glyphs and composites.
This object has been created to reduce the code size of each driver,
as each one of them basically re-implemented its functionality.
See <freetype/internal/ftobjs.h> and the FT_GlyphLoader type for
more information..
- FT_GlyphSlot had new fields:
In order to support extended features (see below), the FT_GlyphSlot
structure has a few new fields:
linearHoriAdvance: this field gives the linearly scaled (i.e.
scaled but unhinted) advance width for the glyph,
expressed as a 16.16 fixed pixel value. This
is useful to perform WYSIWYG text.
linearVertAdvance: this field gives the linearly scaled advance
height for the glyph (relevant in vertical glyph
layouts only). This is useful to perform
WYSIWYG text.
Note that the two above field replace the removed "metrics2" field
in the glyph slot.
advance: this field is a vector that gives the transformed
advance for the glyph. By default, it corresponds
to the advance width, unless FT_LOAD_VERTICAL_LAYOUT
was specified when calling FT_Load_Glyph or FT_Load_Char
bitmap_left: this field gives the distance in integer pixels from
the current pen position to the left-most pixel of
a glyph image WHEN IT IS A BITMAP. It is only valid
when the "format" field is set to
"ft_glyph_format_bitmap", for example, after calling
the new function FT_Render_Glyph.
bitmap_top: this field gives the distance in integer pixels from
the current pen position (located on the baseline) to
the top-most pixel of the glyph image WHEN IT IS A
BITMAP. Positive values correspond to upwards Y.
loader: this is a new private field for the glyph slot. Client
applications should not touch it..
- support for transforms and direct rendering in FT_Load_Glyph:
Most of the functionality found in <freetype/ftglyph.h> has been
moved to the core library. Hence, the following:
- a transform can be specified for a face through FT_Set_Transform.
this transform is applied by FT_Load_Glyph to scalable glyph images
(i.e. NOT TO BITMAPS) before the function returns, unless the
bit flag FT_LOAD_IGNORE_TRANSFORM was set in the load flags..
- once a glyph image has been loaded, it can be directly converted to
a bitmap by using the new FT_Render_Glyph function. Note that this
function takes the glyph image from the glyph slot, and converts
it to a bitmap whose properties are returned in "face.glyph.bitmap",
"face.glyph.bitmap_left" and "face.glyph.bitmap_top". The original
native image might be lost after the conversion.
- when using the new bit flag FT_LOAD_RENDER, the FT_Load_Glyph
and FT_Load_Char functions will call FT_Render_Glyph automatically
when needed.

basic data types redefinitions (i.e. `TT_Int' instead of `FT_Int',

`T1_Fixed' instead of `FT_Fixed'). Hence the format-specific

OLD CHANGES FOR BETA 7
|
2000-05-17 22:56:01 +02:00
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
- bug-fixed the OpenType/CFF parser. It now loads and displays my
|
2001-04-02 23:30:06 +02:00
|
|
|
two fonts nicely, but I'm pretty certain that more testing is
|
|
|
|
|
needed :-)
|
2000-10-31 21:42:18 +01:00
|
|
|
|
2000-06-08 01:41:17 +02:00
|
|
|
- fixed the crummy Type 1 hinter, it now handles accented characters
|
2001-04-02 23:30:06 +02:00
|
|
|
correctly (well, the accent is not always well placed, but that's
|
2000-06-08 01:41:17 +02:00
|
|
|
another problem..)
|
|
|
|
|
|
2007-01-09 11:37:36 +01:00
|
|
|
- added the CID-keyed Type 1 driver in `src/cid'. Works pretty well
|
2001-04-02 23:30:06 +02:00
|
|
|
for only 13 Kb of code ;-) Doesn't read AFM files though, nor the
|
|
|
|
|
really useful CMAP files..
|
2000-06-01 05:27:48 +02:00
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
- fixed two bugs in the smooth renderer (src/base/ftgrays.c).
|
|
|
|
|
Thanks to Boris Letocha for spotting them and providing a fix.
|
2000-06-01 05:27:48 +02:00
|
|
|
|
2007-01-09 11:37:36 +01:00
|
|
|
- fixed potential `divide by zero' bugs in ftcalc.c.
|
2000-05-29 22:55:13 +02:00
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
- added source code for the OpenType/CFF driver (still incomplete
|
|
|
|
|
though..)
|
2000-05-29 22:55:13 +02:00
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
- modified the SFNT driver slightly to perform more robust header
|
2003-09-12 21:38:13 +02:00
|
|
|
checks in TT_Load_SFNT_Header. This prevents certain font files
|
2001-04-02 23:30:06 +02:00
|
|
|
(e.g. some Type 1 Multiple Masters) from being incorrectly
|
2007-01-09 11:37:36 +01:00
|
|
|
`recognized' as TrueType font files..
|
2000-05-29 22:55:13 +02:00
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
- moved a lot of stuff from the TrueType driver to the SFNT module,
|
|
|
|
|
this allows greater code re-use between font drivers
|
|
|
|
|
(e.g. TrueType, OpenType, Compact-TrueType, etc..)
|
2000-05-27 00:13:17 +02:00
|
|
|
|
|
|
|
|
- added a tiny segment cache to the SFNT Charmap 4 decoder, in order
|
|
|
|
|
to minimally speed it up..
|
|
|
|
|
|
2007-01-09 11:37:36 +01:00
|
|
|
- added support for Multiple Master fonts in `type1z'. There is
|
2003-09-12 21:38:13 +02:00
|
|
|
also a new file named <freetype/ftmm.h> which defines functions to
|
2000-05-26 19:13:23 +02:00
|
|
|
manage them from client applications.
|
2000-10-31 21:42:18 +01:00
|
|
|
|
2007-01-09 11:37:36 +01:00
|
|
|
The new file `src/base/ftmm.c' is also optional to the engine..
|
2000-05-26 19:13:23 +02:00
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
- various formatting changes (e.g. EXPORT_DEF -> FT_EXPORT_DEF) +
|
2007-01-09 11:37:36 +01:00
|
|
|
small bug fixes in FT_Load_Glyph, the `type1' driver, etc..
|
2000-05-26 19:13:23 +02:00
|
|
|
|
2000-05-24 00:16:27 +02:00
|
|
|
- a minor fix to the Type 1 driver to let them apply the font matrix
|
|
|
|
|
correctly (used for many oblique fonts..)
|
|
|
|
|
|
2000-05-18 18:18:05 +02:00
|
|
|
- some fixes for 64-bit systems (mainly changing some FT_TRACE calls
|
2003-09-12 21:38:13 +02:00
|
|
|
to use %p instead of %lx). Thanks to Karl Robillard.
|
2000-05-18 18:18:05 +02:00
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
- fixed some bugs in the sbit loader (src/base/sfnt/ttsbit.c) +
|
|
|
|
|
added a new flag, FT_LOAD_CROP_BITMAP to query that bitmaps be
|
|
|
|
|
cropped when loaded from a file (maybe I should move the bitmap
|
|
|
|
|
cropper to the base layer ??).
|
|
|
|
|
|
|
|
|
|
- changed the default number of gray levels of the smooth renderer
|
|
|
|
|
to 256 (instead of the previous 128). Of course, the human eye
|
|
|
|
|
can't see any difference ;-)
|
2000-05-18 01:35:37 +02:00
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
- removed TT_MAX_SUBGLYPHS, there is no static limit on the number
|
|
|
|
|
of subglyphs in a TrueType font now..

|
|
|
|
2007-01-09 11:37:36 +01:00
|
|
|
- tagged `BETA-6' in the CVS tree. This one is a serious release
|
2001-04-02 23:30:06 +02:00
|
|
|
candidate even though it doesn't incorporate the auto-hinter yet..
|
2000-05-17 01:26:01 +02:00
|
|
|
|
|
|
|
|
- various obsolete files were removed, and copyright header updated
|
|
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
- finally updated the standard raster to fix the monochrome

|
|
|
|
rendering bug + re-enable support for 5-gray levels anti-aliasing
|
|
|
|

(suck, suck..)
|
2000-05-17 01:26:01 +02:00

|
|
|
|
|
|
2007-01-09 11:37:36 +01:00
|
|
|
- added the `DSIG' (OpenType Digital Signature) tag to

|
|
|
<freetype/tttags.h>
|
|

- light update/cleaning of the build system + changes to the sources
|
|
|
|
|
in order to get rid of _all_ compiler warnings with three

compilers, i.e:
|
|
|
|
|
|
2007-01-09 11:37:36 +01:00
|
|
|
gcc with `-ansi -pedantic -Wall -W', Visual C++ with `/W3 /WX' and
|
2001-04-02 23:30:06 +02:00
|
|
|
LCC
|
|
|
|
|
|
|
|
|
|
IMPORTANT NOTE FOR WIN32-LCC USERS:
|
|
|
|
|
|
|
|
|
|
|
| It seems the C pre-processor that comes with LCC is broken, it
|
|
|
|
|
| doesn't recognize the ANSI standard directives # and ##
|
2003-09-12 21:38:13 +02:00
|
|
|
| correctly when one of the argument is a macro. Also,
|
|
|
|
|
| something like:
|
2001-04-02 23:30:06 +02:00
|
|
|
|
|
|
|
|
|
| #define F(x) print##x
|
|
|
|
|
|
|
|
|
|
|
| F(("hello"))
|
|
|
|
|
|
|
|
|
|
|
| will get incorrectly translated to:
|
|
|
|
|
|
|
|
|
|
|
| print "hello")
|
|
|
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
| by its pre-processor. For this reason, you simply cannot build
|
2001-04-02 23:30:06 +02:00
|
|
|
| FreeType 2 in debug mode with this compiler..
|
2000-05-12 17:01:18 +02:00
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
- yet another massive grunt work. I've changed the definition of
|
|
|
|
|
the EXPORT_DEF, EXPORT_FUNC, BASE_DEF & BASE_FUNC macros. These
|
|
|
|
|
now take an argument, which is the function's return value type.
|
2000-05-17 01:44:38 +02:00
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
This is necessary to compile FreeType as a DLL on Windows and
|
|
|
|
|
OS/2. Depending on the compiler used, a compiler-specific keyword
|
|
|
|
|
like __export or __system must be placed before (VisualC++) or
|
|
|
|
|
after (BorlandC++) the type..
|
2000-05-17 01:44:38 +02:00
|
|
|
|
2000-05-12 14:17:15 +02:00
|
|
|
Of course, this needed a lot of changes throughout the source code
|
2003-09-12 21:38:13 +02:00
|
|
|
to make it compile again... All cleaned up now, apparently..
|
2000-05-12 14:17:15 +02:00
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
Note also that there is a new EXPORT_VAR macro defined to allow
|
|
|
|
|
the _declaration_ of an exportable public (constant)
|
|
|
|
|
variable. This is the case of the raster interfaces (see
|
|
|
|
|
ftraster.h and ftgrays.h), as well as each module's interface (see
|
|
|
|
|
sfdriver.h, psdriver.h, etc..)
|
2000-05-12 14:17:15 +02:00
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
- new feature: it is now possible to pass extra parameters to font
|
|
|
|
|
drivers when creating a new face object. For now,
|
|
|
|
|
this capability is unused. It could however prove to
|
|
|
|
|
be useful in a near future..
|
2000-05-12 14:17:15 +02:00
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
the FT_Open_Args structure was changes, as well as the internal
|
2007-01-09 11:37:36 +01:00
|
|
|
driver interface (the specific `init_face' module function has
|
2001-04-02 23:30:06 +02:00
|
|
|
now a different signature).
|
2000-05-12 14:17:15 +02:00
|
|
|
|
|
|
|
|
- updated the tutorial (not finished though).
|
2001-04-02 23:30:06 +02:00
|
|
|
|
2000-05-12 17:01:18 +02:00
|
|
|
- updated the top-level BUILD document
|
2000-05-12 14:17:15 +02:00
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
- fixed a potential memory leak that could occur when loading
|
|
|
|
|
embedded bitmaps.
|
2000-05-12 17:26:58 +02:00
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
- added the declaration of FT_New_Memory_Face in
|
|
|
|
|
<freetype/freetype.h>, as it was missing from the public header
|
2007-01-09 11:37:36 +01:00
|
|
|
(the implementation was already in `ftobjs.c').
|
2000-05-12 14:17:15 +02:00
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
- the file <freetype/fterrors.h> has been seriously updated in order
|
2003-09-12 21:38:13 +02:00
|
|
|
to allow the automatic generation of error message tables. See
|
|
|
|
|
the comments within it for more information.

|
|
- major directory hierarchy re-organisation. This was done for two
|
2001-04-02 23:30:06 +02:00
|
|
|
things:
|
2000-05-17 01:44:38 +02:00
|
|
|
|
2007-01-09 11:37:36 +01:00
|
|
|
* first, to ease the `manual' compilation of the library by
|
2001-04-02 23:30:06 +02:00
|
|
|
requiring at lot less include paths :-)
|
2000-05-12 14:17:15 +02:00
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
* second, to allow external programs to effectively access
|
2003-09-12 21:38:13 +02:00
|
|
|
internal data fields. For example, this can be extremely
|
2001-04-02 23:30:06 +02:00
|
|
|
useful if someone wants to write a font producer or a font
|
|
|
|
|
manager on top of FreeType.
|
2000-05-11 20:36:19 +02:00
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
Basically, you should now use the 'freetype/' prefix for header
|
|
|
|
|
inclusion, as in:
|
2000-05-17 01:44:38 +02:00
|
|
|
|
2000-05-11 20:36:19 +02:00
|
|
|
#include <freetype/freetype.h>
|
|
|
|
|
#include <freetype/ftglyph.h>
|
|
|
|
|
|
|
|
|
|
Some new include sub-directories are available:
|
2000-05-17 01:44:38 +02:00
|
|
|
|
2007-01-09 11:37:36 +01:00
|
|
|
a. the `freetype/config' directory, contains two files used to
|
2003-09-12 21:38:13 +02:00
|
|
|
configure the build of the library. Client applications
|
|
|
|
|
should not need to look at these normally, but they can if
|
|
|
|
|
they want.
|
2000-05-17 01:44:38 +02:00
|
|
|
|
2000-05-11 20:36:19 +02:00
|
|
|
#include <freetype/config/ftoption.h>
|
|
|
|
|
#include <freetype/config/ftconfig.h>
|
2000-05-17 01:44:38 +02:00
|
|
|
|
2007-01-09 11:37:36 +01:00
|
|
|
b. the `freetype/internal' directory, contains header files that
|
2003-09-12 21:38:13 +02:00
|
|
|
describes library internals. These are the header files that
|
2007-01-09 11:37:36 +01:00
|
|
|
were previously found in the `src/base' and `src/shared'
|
2001-04-02 23:30:06 +02:00
|
|
|
directories.
|
2000-05-11 20:36:19 +02:00
|
|
|
|
|
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
As usual, the build system and the demos have been updated to
|
|
|
|
|
reflect the change..
|
2000-05-17 01:44:38 +02:00
|
|
|
|
2000-05-11 20:36:19 +02:00

Compiling a module is now much easier, for example, the following
|
2002-06-14 10:09:25 +02:00
|
|
|
should work when in the TOP_DIR directory on an ANSI build:
|
2000-05-17 01:44:38 +02:00
|
|
|
|
2000-05-11 20:36:19 +02:00
|
|
|
gcc -c -I./include -I./src/base src/base/ftbase.c
|
|
|
|
|
gcc -c -I./include -I./src/sfnt src/sfnt/sfnt.c
|
|
|
|
|
etc..
|
|
|
|
|
|
|
|
|
|
(of course, using -Iconfig/<system> if you provide system-specific
|
|
|
|
|
configuration files).
|
2000-05-11 20:23:52 +02:00
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
- updated the structure of FT_Outline_Funcs in order to allow direct
|
|
|
|
|
coordinate scaling within the outline decomposition routine (this
|
2007-01-09 11:37:36 +01:00
|
|
|
is important for virtual `on' points with TrueType outlines) +
|
2001-04-02 23:30:06 +02:00
|
|
|
updates to the rasters to support this..
|
2000-05-11 20:23:52 +02:00
|
|
|
|
2007-01-09 11:37:36 +01:00
|
|
|
- updated the OS/2 table loading code in `src/sfnt/ttload.c' in
|
2001-04-02 23:30:06 +02:00
|
|
|
order to support version 2 of the table (see OpenType 1.2 spec)
|
2000-05-11 20:23:52 +02:00
|
|
|
|
2007-01-09 11:37:36 +01:00
|
|
|
- created `include/tttables.h' and `include/t1tables.h' to allow
|
2001-04-02 23:30:06 +02:00
|
|
|
client applications to access some of the SFNT and T1 tables of a
|
2007-01-09 11:37:36 +01:00
|
|
|
face with a procedural interface (see `FT_Get_Sfnt_Table') +
|
2001-04-02 23:30:06 +02:00
|
|
|
updates to internal source files to reflect the change..
|
2000-05-11 20:23:52 +02:00
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
- some cleanups in the source code to get rid of warnings when
|
2007-01-09 11:37:36 +01:00
|
|
|
compiling with the `-Wall -W -ansi -pedantic' options in gcc.
|
2000-05-11 20:23:52 +02:00
|
|
|
|
2007-01-09 11:37:36 +01:00
|
|
|
- debugged and moved the smooth renderer to `src/base/ftgrays.c' and
|
|
|
|
|
its header to `include/ftgrays.h'
|
2000-05-11 20:23:52 +02:00
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
- updated TT_MAX_SUBGLYPHS to 96 as some CJK fonts have composites
|
|
|
|
|
with up to 80 sub-glyphs !! Thanks to Werner
|

|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
- fixed a bug in the TrueType glyph loader that prevented the
|
|
|
|
|
correct loading of some CJK glyphs in mingli.ttf
|
2000-05-17 01:44:38 +02:00
|
|
|
|
2007-01-09 11:37:36 +01:00

2000-05-17 01:44:38 +02:00
|
|
|
|
2007-01-09 11:37:36 +01:00
|
|
|
- fixed two bugs in the experimental Type 1 driver in `src/type1z'
|
2000-04-14 22:49:52 +02:00
|
|
|
to handle the new XFree86 4.0 fonts (and a few other ones..)
|
|
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
- the smooth renderer is now complete and supports sub-banding to
|
2003-09-12 21:38:13 +02:00
|
|
|
render large glyphs at high speed. However, it is still located
|
2007-01-09 11:37:36 +01:00
|
|
|
in `demos/src/ftgrays.c' and should move to the library itself in
|
2003-09-12 21:38:13 +02:00
|
|
|
the next beta. NOTE: The smooth renderer doesn't compile in
|
2000-04-14 22:49:52 +02:00
|
|
|
stand-alone mode anymore, but this should be fixed RSN..
|
2000-05-17 01:44:38 +02:00
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
- introduced convenience functions to more easily deal with glyph
|
2007-01-09 11:37:36 +01:00
|
|
|
images, see `include/ftglyph.h' for more details, as well as the
|
|
|
|
|
new demo program named `demos/src/ftstring.c' that demonstrates
|
2000-04-14 22:49:52 +02:00
|
|
|
its use
|
|
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
- implemented FT_LOAD_NO_RECURSE in both the TrueType and Type 1
|
|
|
|
|
drivers (this is required by the auto-hinter to improve its
|
|
|
|
|
results).
|
2000-04-14 22:49:52 +02:00
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
- changed the raster interface, in order to allow client
|
2003-09-12 21:38:13 +02:00
|
|
|
applications to provide their own span-drawing callbacks.
|
|
|
|
|
However, only the smooth renderer supports this. See
|
2007-01-09 11:37:36 +01:00
|
|
|
`FT_Raster_Params' in the file `include/ftimage.h'.

|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
- fixed a small bug in FT_MulFix that caused incorrect transform
|
|
|
|
|
computation!

OLD CHANGES - 22-feb-2000
|
2000-02-22 15:31:42 +01:00
|
|
|
|
2007-01-09 11:37:36 +01:00
|
|
|
- introduced the `psnames' module. It is used to:
|
2000-02-22 15:31:42 +01:00
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
o convert a Postscript glyph name into the equivalent Unicode
|
2007-01-17 13:45:26 +01:00
|
|
|
character code (used by the Type 1 driver(s) to synthesize on
|
2001-04-02 23:30:06 +02:00
|
|
|
the fly a Unicode charmap).
|
|
|
|
|
|
|
|
|
|
o provide an interface to retrieve the Postscript names of the
|
|
|
|
|
Macintosh, Adobe Standard & Adobe Expert character codes.
|
|
|
|
|
(the Macintosh names are used by the SFNT-module postscript
|
|
|
|
|
names support routines, while the other two tables are used by
|
|
|
|
|
the Type 1 driver(s)).
|
|
|
|
|
|
2007-01-09 11:37:36 +01:00
|
|
|
- introduced the `type1z' alternate Type 1 driver. This is a (still
|
2001-04-02 23:30:06 +02:00
|
|
|
experimental) driver for the Type 1 format that will ultimately
|
2007-01-09 11:37:36 +01:00
|
|
|
replace the one in `src/type1'. It uses pattern matching to load
|
2003-09-12 21:38:13 +02:00
|
|
|
data from the font, instead of a finite state analyzer. It works
|
2007-01-09 11:37:36 +01:00
|
|
|
much better than the `old' driver with `broken' fonts. It is also
|
2000-02-22 15:31:42 +01:00
|
|
|
much smaller (under 15 Kb).
|
|
|
|
|
|
2007-01-09 11:37:36 +01:00
|
|
|
- the Type 1 drivers (both in `src/type1' and `src/type1z') are
|
2001-04-02 23:30:06 +02:00
|
|
|
nearly complete. They both provide automatic Unicode charmap
|
2007-01-09 11:37:36 +01:00
|
|
|
synthesis through the `psnames' module. No re-encoding vector is
|
2001-04-02 23:30:06 +02:00
|
|
|
needed. (note that they still leak memory due to some code
|
2000-02-22 15:31:42 +01:00
|
|
|
missing, and I'm getting lazy).
|
|
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
Trivial AFM support has been added to read kerning information but
|
|
|
|
|
wasn't exactly tested as it should ;-)
|
2000-02-22 15:31:42 +01:00
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
- The TrueType glyph loader has been seriously rewritten (see the
|
2007-01-09 11:37:36 +01:00
|
|
|
file `src/truetype/ttgload.c'. It is now much, much simpler as
|
2001-04-02 23:30:06 +02:00
|
|
|
well as easier to read, maintain and understand :-) Preliminary
|
|
|
|
|
versions introduced a memory leak that has been reported by Jack
|
2000-02-22 15:31:42 +01:00
|
|
|
Davis, and is now fixed..
|
|
|
|
|
|
2007-01-09 11:37:36 +01:00
|
|
|
- introduced the new `ft_glyph_format_plotter', used to represent
|
|
|
|
|
stroked outlines like Windows `Vector' fonts, and certain Type 1
|
|
|
|
|
fonts like `Hershey'. The corresponding raster will be written
|
2000-02-22 15:31:42 +01:00
|
|
|
soon.
|
|
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
- FT_New_Memory_Face is gone. Likewise, FT_Open_Face has a new
|
|
|
|
|
interface that uses a structure to describe the input stream, the
|
|
|
|
|
driver (if required), etc..
|
|
|

- Write FT_Get_Glyph_Bitmap and FT_Load_Glyph_Bitmap
|
|
|
|
|
|
2007-01-17 13:45:26 +01:00
|
|
|
- Add a function like FT_Load_Character(face, char_code, load_flags)
|
|
|
|
|
that would really embed a call to FT_Get_Char_Index then
|
2001-04-02 23:30:06 +02:00
|
|
|
FT_Load_Glyph to ease developer's work.

|
|
|
- consider adding support for Multiple Master fonts in the Type 1

|
|
drivers.
|
|
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
- Test the AFM routines of the Type 1 drivers to check that kerning
|
2000-02-22 15:31:42 +01:00
|
|
|
information is returned correctly.
|
|
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
- write a decent auto-gridding component !! We need this to release

less urgent needs:
|
|
|
|
|
|
2000-02-22 15:31:42 +01:00

OLDER CHANGES - 27-jan-2000
|
2000-01-27 15:07:33 +01:00
|
|
|
|
2007-01-09 11:37:36 +01:00
|
|
|
- updated the `sfnt' module interface to allow several SFNT-based
|
2000-01-27 15:07:33 +01:00
|
|
|
drivers to co-exist peacefully
|
2000-05-17 01:44:38 +02:00
|
|
|
|
2007-01-09 11:37:36 +01:00
|
|
|
- updated the `T1_Face' type to better separate Postscript font
|
2003-09-12 21:38:13 +02:00
|
|
|
content from the rest of the FT_Face structure. Might be used
|
2001-04-02 23:30:06 +02:00
|
|
|
later by the CFF/Type2 driver..
|
2000-05-17 01:44:38 +02:00
|
|
|
|
2000-01-27 15:07:33 +01:00
|
|
|
- added an experimental replacement Type 1 driver featuring advanced
|
|
|
|
|
(and speedy) pattern matching to retrieve the data from postscript
|
|
|
|
|
fonts.
|
|
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
- very minor changes in the implementation of FT_Set_Char_Size and
|
2007-01-17 13:45:26 +01:00
|
|
|
FT_Set_Pixel_Sizes (they now implement default to lighten the font

|
|
driver's code).

This file summarizes the changes that occurred since the last `beta'
|
|
|
|
|
of FreeType 2. Because the list is important, it has been divided into
|
2001-04-02 23:30:06 +02:00
|
|
|
separate sections:

High-Level Interface:
|
1999-12-17 00:11:37 +01:00
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
The high-level API has been considerably simplified. Here is how:
|
2000-05-17 01:44:38 +02:00
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
- resource objects have disappeared. this means that face objects
|
|
|
|
|
can now be created with a single function call (see FT_New_Face
|
|
|
|
|
and FT_Open_Face)
|
2000-05-17 01:44:38 +02:00
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
- when calling either FT_New_Face & FT_Open_Face, a size object
|
|
|
|
|
and a glyph slot object are automatically created for the face,
|
2007-01-09 11:37:36 +01:00
|
|
|
and can be accessed through `face->glyph' and `face->size' if
|
2001-04-02 23:30:06 +02:00
|
|
|
one really needs to. In most cases, there's no need to call
|
|
|
|
|
FT_New_Size or FT_New_Glyph.
|
2000-05-17 01:44:38 +02:00
|
|
|
|
2007-01-09 11:37:36 +01:00
|
|
|
- similarly, FT_Load_Glyph now only takes a `face' argument
|
2007-02-01 08:58:02 +01:00
|
|
|
(instead of a glyph slot and a size). Also, its `result'
|
2001-04-02 23:30:06 +02:00
|
|
|
parameter is gone, as the glyph image type is returned in the
|
2007-01-09 11:37:36 +01:00
|
|
|
field `face->glyph.format'
|
2001-04-02 23:30:06 +02:00
|
|
|
|
|
|
|
|
- the list of available charmaps is directly accessible through
|
2007-01-09 11:37:36 +01:00
|
|
|
`face->charmaps', counting `face->num_charmaps' elements. Each
|
2001-04-02 23:30:06 +02:00
|
|
|
charmap has an 'encoding' field which specifies which known
|
2003-09-12 21:38:13 +02:00
|
|
|
encoding it deals with. Valid values are, for example:
|
2000-05-17 01:44:38 +02:00
|
|
|
|
1999-12-17 00:11:37 +01:00
|
|
|
ft_encoding_unicode (for ASCII, Latin-1 and Unicode)
|
|
|
|
|
ft_encoding_apple_roman
|
|
|
|
|
ft_encoding_sjis
|
|
|
|
|
ft_encoding_adobe_standard
|
1999-12-29 01:53:44 +01:00
|
|
|
ft_encoding_adobe_expert
|
2000-05-17 01:44:38 +02:00
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
other values may be added in the future. Each charmap still
|
2007-01-09 11:37:36 +01:00
|
|
|
holds its `platform_id' and `encoding_id' values in case the
|
2001-04-02 23:30:06 +02:00
|
|
|
encoding is too exotic for the current library
|
|
|
|
|

Glyph Image Formats:
|
|
|
|
|
|
|
|
|
|
Drivers are now able to register new glyph image formats within the
|
|
|
|
|
library. For now, the base layer supports of course bitmaps and
|
|
|
|
|
vector outlines, but one could imagine something different like
|
2007-01-17 13:45:26 +01:00
|
|
|
colored bitmaps, bi-color vectors or whatever else (Metafonts anyone
|
2001-04-02 23:30:06 +02:00
|
|
|
??).
|
|
|
|
|
|
|
|
|
|
See the file `include/ftimage.h'. Note also that the type
|
|
|
|
|
FT_Raster_Map is gone, and is now replaced by FT_Bitmap, which
|
|
|
|
|
should encompass all known bitmap types.

Each new image format must provide at least one `raster', i.e. a
|
2003-09-12 21:38:13 +02:00
|
|
|
module capable of transforming the glyph image into a bitmap. It's
|
2001-04-02 23:30:06 +02:00
|
|
|
also possible to change the default raster used for a given glyph
|
|
|
|
|
image format.

The default outline scan-converter now uses 128 levels of grays by
|
2003-09-12 21:38:13 +02:00
|
|
|
default, which tends to smooth many things. Note that the demo
|
2001-04-02 23:30:06 +02:00
|
|
|
programs have been updated significantly in order to display these..

Build system:
|
1999-12-17 00:11:37 +01:00
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
You still need GNU Make to build the library. The build system has
|
|
|
|
|
been very seriously re-vamped in order to provide things like :
|
1999-12-17 00:11:37 +01:00
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
- automatic host platform detection (reverting to 'config/ansi' if
|
|
|
|
|
it is not detected, with pseudo-standard compilation flags)
|
1999-12-17 00:11:37 +01:00
|
|
|
|
|
|
|
|
- the ability to compile from the Makefiles with very different and
|
2003-09-12 21:38:13 +02:00
|
|
|
exotic compilers. Note that linking the library can be difficult
|
2001-04-02 23:30:06 +02:00
|
|
|
for some platforms.
|
1999-12-17 00:11:37 +01:00
|
|
|
|
|
|
|
|
For example, the file `config/win32/lcclib.bat' is invoked by the
|
2007-01-09 11:37:36 +01:00
|
|
|
build system to create the `.lib' file with LCC-Win32 because its
|
2001-04-02 23:30:06 +02:00
|
|
|
librarian has too many flaws to be invoked directly from the
|
|
|
|
|
Makefile.
|
1999-12-17 00:11:37 +01:00
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
Here's how it works:
|
1999-12-17 00:11:37 +01:00
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
- the first time you type `make', the build system runs a series of
|
2003-09-12 21:38:13 +02:00
|
|
|
sub-makefiles in order to detect your host platform. It then
|
|
|
|
|
dumps what it found, and creates a file called `config.mk' in the
|
|
|
|
|
current directory. This is a sub-Makefile used to define many
|
2001-04-02 23:30:06 +02:00
|
|
|
important Make variables used to build the library.
|
1999-12-17 00:11:37 +01:00
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
- the second time, the build system detects the `config.mk' then use
|
|
|
|
|
it to build the library. All object files go into 'obj' by
|
|
|
|
|
default, as well as the library file, but this can easily be
|
|
|
|
|
changed.
|
1999-12-17 00:11:37 +01:00
|
|
|
|
2007-01-09 11:37:36 +01:00
|
|
|
Note that you can run `make setup' to force another host platform
|
2001-04-02 23:30:06 +02:00
|
|
|
detection even if a `config.mk' is present in the current
|
|
|
|
|
directory. Another solution is simply to delete the file, then
|
|
|
|
|
re-run make.
|
1999-12-17 00:11:37 +01:00
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
Finally, the default compiler for all platforms is gcc (for now,
|
2003-09-12 21:38:13 +02:00
|
|
|
this will hopefully changed in the future). You can however specify
|
2001-04-02 23:30:06 +02:00
|
|
|
a different compiler by specifying it after the 'setup' target as
|
|
|
|
|
in:
|
1999-12-17 00:11:37 +01:00
|
|
|
|
|
|
|
|
gnumake setup lcc on Win32 to use the LCC compiler
|
|
|
|
|
gnumake setup visualc on Win32 to use Visual C++
|
|
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
See the file `config/<system>/detect.mk' for a list of supported
|
|
|
|
|
compilers for your platforms.
|
1999-12-17 00:11:37 +01:00
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
It should be relatively easy to write new detection rules files and
|
1999-12-17 00:11:37 +01:00
|
|
|
config.mk..
|
|
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
Finally, to build the demo programs, go to `demos' and launch GNU
|
|
|
|
|
Make, it will use the `config.mk' in the top directory to build the
|
|
|
|
|
test programs..

Portability:

In the previous beta, a single FT_System object was used to
|
|
|
|
|
encompass all low-level operations like thread synchronisation,
|
2003-09-12 21:38:13 +02:00
|
|
|
memory management and i/o access. This has been greatly simplified:
|
2001-04-02 23:30:06 +02:00
|
|
|
|
|
|
|
|
- thread synchronisation has been dropped, for the simple reason
|
|
|
|
|
that the library is already re-entrant, and that if you really
|
|
|
|
|
need two threads accessing the same FT_Library, you should
|
|
|
|
|
really synchronize access to it yourself with a simple mutex.
|
|
|
|
|
|
|
|
|
|
- memory management is performed through a very simple object
|
2007-01-09 11:37:36 +01:00
|
|
|
called `FT_Memory', which really is a table containing a table
|
2001-04-02 23:30:06 +02:00
|
|
|
of pointers to functions like malloc, realloc and free as well
|
|
|
|
|
as some user data (closure).
|
1999-12-17 00:11:37 +01:00
|
|
|
|
|
|
|
|
- resources have disappeared (they created more problems than they
|
2001-04-02 23:30:06 +02:00
|
|
|
solved), and i/o management have been simplified greatly as a
|
2003-09-12 21:38:13 +02:00
|
|
|
result. Streams are defined through FT_Stream objects, which
|
|
|
|
|
can be either memory-based or disk-based.
|
1999-12-17 00:11:37 +01:00
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
Note that each face has its own stream, which is closed only
|
|
|
|
|
when the face object is destroyed. Hence, a function like
|
2003-09-12 21:38:13 +02:00
|
|
|
TT_Flush_Face in 1.x cannot be directly supported. However, if
|
2001-04-02 23:30:06 +02:00
|
|
|
you really need something like this, you can easily tailor your
|
|
|
|
|
own streams to achieve the same feature at a lower level (and
|
|
|
|
|
use FT_Open_Face instead of FT_New_Face to create the face).
|

See the file `include/ftsystem.h' for more details, as well as the
|
|
|
|
|
implementations found in `config/unix' and `config/ansi'.

Font Drivers:

|
The Font Driver interface has been modified in order to support
|
1999-12-29 01:53:44 +01:00
|
|
|
extensions & versioning.
|
|
|
|
|
|
|
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
The list of the font drivers that are statically linked to the
|
|
|
|
|
library at compile time is managed through a new configuration file
|
1999-12-29 01:53:44 +01:00
|
|
|
called `config/<platform>/ftmodule.h'.
|
|
|
|
|
|
2003-09-12 21:38:13 +02:00
|
|
|
This file is autogenerated when invoking `make modules'. This
|
|
|
|
|
target will parse all sub-directories of 'src', looking for a
|
2007-01-09 11:37:36 +01:00
|
|
|
`module.mk' rules file, used to describe the driver to the build
|
2003-09-12 21:38:13 +02:00
|
|
|
system.
|
1999-12-29 01:53:44 +01:00
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
Hence, one should call `make modules' each time a font driver is
|
|
|
|
|
added or removed from the `src' directory.
|
1999-12-29 01:53:44 +01:00
|
|
|
|
2007-01-09 11:37:36 +01:00
|
|
|
Finally, this version provides a `pseudo-driver' in `src/sfnt'.
|
2003-09-12 21:38:13 +02:00
|
|
|
This driver doesn't support font files directly, but provides
|
|
|
|
|
services used by all TrueType-like font drivers. Hence, its code is
|
|
|
|
|
shared between the TrueType & OpenType font formats, and possibly
|
|
|
|
|
more formats to come if we're lucky..
|
2001-04-02 23:30:06 +02:00
|
|
|
|
|
|
|
|
|
|

1999-12-17 00:11:37 +01:00

|
Extensions support:
|
1999-12-29 01:53:44 +01:00
|
|
|
|
|
|
|
|
The extensions support is inspired by the one found in 1.x.
|
|
|
|
|
|
2007-01-09 11:37:36 +01:00
|
|
|
Now, each font driver has its own `extension registry', which lists
|
2001-04-02 23:30:06 +02:00
|
|
|
which extensions are available for the font faces managed by the
|
|
|
|
|
driver.
|
1999-12-29 01:53:44 +01:00
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
Extension ids are now strings, rather than 4-byte tags, as this is
|
2003-09-12 21:38:13 +02:00
|
|
|
usually more readable.
|
1999-12-29 01:53:44 +01:00
|
|
|
|
|
|
|
|
Each extension has:
|
|
|
|
|
- some data, associated to each face object
|
|
|
|
|
- an interface (table of function pointers)
|
|
|
|
|
|
2001-04-02 23:30:06 +02:00
|
|
|
An extension that is format-specific should simply register itself
|
2003-09-12 21:38:13 +02:00
|
|
|
to the correct font driver. Here is some example code:
