[truetype] Retain OVERLAP_SIMPLE and OVERLAP_COMPOUND.
|

|
||
For glyphs with OVERLAP_SIMPLE or OVERLAP_COMPOUND, set

[build] Really fix multi and C++ builds.
|

|
||
The following builds were still failing due to previous changes:
|
||
|
||
make multi
|
||
make multi CC="c++"
|
||
make CC="c++"
|
||
|
||
This patch fixes the issues, which were missing includes to get the
|
||
right macro definitions in multi-build mode.
|
||
|
||
Also, `FT_UNUSED' is actually used by third-party code, so move it
|
||
back to `public-macros.h' to avoid breaking it.
|
||
|
||
* include/freetype/config/public-macros.h (FT_EXPORT): Remove
|
||
special definition for C++.
|
||
(FT_UNUSED): Define here instead of...
|
||
* include/freetype/config/compiler-macros.h: ... here.
|
||
(FT_FUNCTION_DECLARATION): Remove special definition for C++.
|
||
(FT_LOCAL_ARRAY_DEF): Fix definition.
|
||
|
||
* src/cache/ftccback.h, src/lzw/ftzopen.h, src/gxvalid/gxvmort.h,

2020-07-05 David Turner <david@freetype.org>

[build] Improve visibility support of library function names.
|
||
|
||
* include/freetype/config/public-macros.h
|
||
(FT_PUBLIC_FUNCTION_ATTRIBUTE): New macro to tag functions as
|
||
public (and thus exportable).
|
||
(FT_EXPORT): Use it.
|
||
|
||
* include/freetype/config/compiler-macros.h
|
||
(FT_INTERNAL_FUNCTION_ATTRIBUTE): New macro to tag functions as
|
||
internal to the library (and thus hidden). Note that on ELF
|
||
systems, all internal functions have hidden visibility, which avoids
|
||
the need to enforce this when invoking the compiler (e.g., with an
|
||
option like `-fvisibility=hidden').
|
||
|
||
(FT_FUNCTION_DECLARATION, FT_FUNCTION_DEFINITION): New base macros
|
||
to deal with C and C++ linkage issues at the same time.
|

|
||
|

* builds/unix/ftconfig.h.in, builds/vms/ftconfig.h,

include/freetype/config/ftconfig.h: Split off macro definitions used

|
||
|

* builds/unix/ftconfig.h.in, builds/vms/ftconfig.h,
|

include/freetype/config/ftconfig.h: Split off mac-specific stuff
|
||
to...
|
||
* include/freetype/config/mac-support.h: ...this new file.
|
||
|
||
* CMakeLists.txt, builds/unix/configure.raw: Remove `/undef ->

the `ftconfig.h' template.
|
||
|
||
2020-07-05 David Turner <david@freetype.org>
|
||
|
||
[build] Put integer type definitions into `integer-types.h'.
|
||
|
||
Refactor some of the `ftconfig.h' headers and template to move the
|
||
definition of the FreeType integer types (e.g., `FT_Int16') to a
|
||
common header file `freetype/config/integer-types.h'.
|
||
|
||
* builds/unix/ftconfig.h.in, builds/vms/ftconfig.h,
|
||
include/freetype/config/ftconfig.h: Split off integer type
|
||
definition stuff to...
|
||
* include/freetype/config/integer-types.h: ...this new file.
|
||
|
||
* builds/unix/ftconfig.h.in: Control the definition of
|
||
`FT_SIZEOF_INT' and `FT_SIZEOF_LONG' with macro
|
||
`FT_USE_AUTOCONF_SIZEOF_TYPES'. If these are not defined, auto
|
||
detection happens in `integer-types.h' as usual based on `INTXX_MAX'
|
||
values. Otherwise the autoconf-detected values are used.
|
||
|
||
* builds/unix/configure.raw (CPPFLAGS): Don't include path to
|
||
`config' directory. Instead, ...
|
||
(FT_CONFIG_STANDARD_LIBRARY_H): Use complete path.
|
||
|
||
2020-07-05 David Turner <david@freetype.org>
|
||
|
||
[build] Rename `build/unix/ftconfig.in' to `ftconfig.h.in'.
|
||
|
||
Since we are no longer limited to 8.3 file names, it is simpler to
|
||
follow the usual conventions for template files.
|
||
|
||
* builds/unix/ftconfig.in: Renamed to...

* builds/unix/ftconfig.h.in: ...this.

|
||
[smooth] Introduce direct oversampling for overlaps.
|
||
|
||
This implements oversampling to mitigate artifacts in pixels partially
|
||
covered by overlapping contours. It turns out that the 4x4
|
||
oversampling is sufficient but, at least, quadruples the rendering
|
||
time. The outline has to set FT_OUTLINE_OVERLAP to use this method.
|
||
|
||
* include/freetype/ftimage.h (FT_OUTLINE_OVERLAP): New flag.
|
||
* src/smooth/ftsmooth.c (ft_smooth_render): Check it to...
|
||
(ft_smooth_raster_overlap): ... inflate outline and set up direct
|
||
rendering for oversampling with...
|
||
(ft_smooth_overlap_spans): ... new span function that integrates them.
|
||
|
||
2020-07-03 Alexei Podtelezhnikov <apodtele@gmail.com>
|
||
|
||
[smooth] Use direct rendering mode in Harmony.
|
||
|
||
Instead of rendering 3 bitmaps side by side and reshuffling, we use
|
||
direct rendering to deliver the bitmaps on each third byte.
|
||
|
||
* src/smooth/ftsmooth.c (ft_smooth_raster_lcd)
|
||
[!FT_CONFIG_OPTION_SUBPIXEL_RENDERING]: Set up direct mode with...

(ft_smooth_lcd_spans): ... new span function.
|

|
||
2020-07-03 Alexei Podtelezhnikov <apodtele@gmail.com>
|
||
|
||
[smooth] Separate LCD paths from gray rendering.
|
||
|
||
This makes `ft_smooth_render' a lot smaller and easier to follow. It
|
||
also cleanly separates Harmony and ClearType-style LCD rendering
|
||
algorithms. Now I only wish to move LCD filtering and geometry from
|
||
FT_Library to FT_Renderer.
|
||
|
||
* src/smooth/ftsmooth.c (ft_smooth_render): Move LCD code from here...
|
||
(ft_smooth_raster_lcd, ft_smooth_raster_lcdv): ... to here.
|
||
[FT_CONFIG_OPTION_SUBPIXEL_RENDERING]: Reorganize #ifdef's.

[cff] Fix handling of `style_name == NULL' (#58630).
|
||
|
||
* src/cff/cffobjs.c (cff_face_init): If a call to `cff_strcpy' fails
|
||
by returning NULL in `cff_face_init', `remove_style' is still
|
||
called. This means that the NULL pointer is dereferenced, causing a

crash.

subfonts.

appeared in the fix for issue #58611.
|

|
||
|
||
* src/cff/cffobjs.c (cff_slot_done), src/cid/cidobjs.c

||
(cid_slot_done): If `ft_glyphslot_init' fails to allocate

`internal', then the class' `done_slot' callback (called by

|
||
|
||
Make macros for header file names optional.
|
||
|
||
We no longer have to take care of the 8.3 file name limit; this
|
||
allows us (a) to introduce longer, meaningful file names, and (b) to
|
||
avoid macro names in `#include' lines altogether since some
|
||
compilers (most notably Visual C++) doesn't support this properly.
|
||
|

*/*: Replace

[gzip] Support `gzip' encoded header conditionally.
|
||
|
||
In order to support `gzip' encoded header the call to
|
||
`inflateInit2' was modified in commit 6a92b1fadde26477a9179.
|
||
However, this code breaks with the outdated internal version
|
||
of zlib. This is a temporary fix to conditionally support
|
||
`gzip' encoded header whenever a system installation of zlib
|
||
is being used.
|
||
|
||

[truetype] Fix state of `FT_Face' for buggy `gvar' tables (#57923).
|
||
|

By resetting the blend as implemented with this commit fonts with

invalid `gvar' tables may keep calling into `ft_var_load_gvar' from
|
||
`tt_set_mm_blend' and failing, but the font was invalid anyway and

we want to keep seeing the failure in `tt_set_mm_blend'.

||
Allocate arrays after `FT_FRAME_ENTER' (extra check before

allocating and avoid needing to free array later if error entering
|
||
frame).
|
||
Always call `FT_FRAME_EXIT'.
|
||
Consistently set counts immediately after array initialized.

(reconstruct_font): Change `FT_Byte* sfnt' to `FT_Byte**
|
||
sfnt_bytes'. This has been done because we reallocate memory to
|
||
`sfnt' multiple times, which may change the pointer value of `sfnt'.
|
||
This new pointer must be propogated back to the caller. Same reason
|
||
for using a double pointer in `write_buf'.

[woff2] Get known tags from function.
|
||

Change `KnownTags' to a function (`woff2_known_tags'). This avoids

specified index without *any* checks. The caller must ensure that
|

[woff2] Uncompress Brotli streams and `face_index' support.
|
||
|
||
WOFF2 compressed stream is now uncompressed if Brotli is available.
|
||
This data is stored in a separate buffer (uncompressed_buf) because
|
||
it does not contain direct table data. Certain tables have
|
||
transformations applied to them, and they must be reconstructed
|
||
before we can write those tables to the SFNT stream.
|
||

|
||
|
||
[psaux] (1/2) Handle fonts that use SEAC for ligatures (#56580).
|
||
|
||
As originally intended, a Type 1 SEAC charstring would be used for
|
||
an accented glyph (like `acaron' or `uumlaut'), where the advance
|
||
width of the SEAC glyph is the same as that of the `base' glyph
|
||
(like `a' or `u'). In this case it is not uncommon for the SEAC
|
||
glyph to not use an (H)SBW opcode of its own but to rely on the
|
||
value from the base glyph.
|
||
|
||
However, out-of-spec fonts also use SEAC glyphs for ligatures (like
|
||
`oe' or `fi'), and in those cases the overall advance width is
|
||
greater than that of the `base' glyph. For this reason we have to
|
||
allow that the SEAC glyph can have an (H)SBW value of its own, and
|
||
if it has, retain this value, rather than the one from the base
|
||
glyph.
|
||
|
||
* src/psaux/psintrp.c (cf2_interpT2CharString) <cf2_escSEAC>:
|
||
Implement it.

||
[smooth] Simplify cubic Bézier flattening.
|
||
|
||
The previous implementation is correct but it is too complex.
|
||
The revised algorithm is based on the fact that each split moves
|
||
the control points closer to the trisection points on the chord.
|
||
The corresponding distances are good surrogates for the curve
|
||
deviation from the straight line.
|
||
|
||
This cubic flattening algorithm is somewhat similar to the conic
|
||
algorithm based the distance from the control point to the middle of
|
||
the chord. The cubic distances, however, decrease less predictably
|
||
but are easy enough to calculate on each step.
|
||
|
||
The new algorithm produces slightly larger number of splits, which is
|
||
compensated by its simplicity. The overall rendering performance is
|
||
improved by 1-2%. The larger number of splits does not necessarily
|
||
result in higher quality, which stays comparable.
|
||
|
||
* src/smooth/ftgrays.c (gray_render_cubic): Replace the split
|
||
condition.

||
Optimize Bézier bisections.
|
||
|
||
This change makes bisections faster by 20-30%. When inlined into

|
||
noticeable in the overall rendering performance.
|

[pcf] Fix handling of undefined glyph (#56067).

This commit fixes the changes from 2018-07-21, which broke charmap

[cff] Fix boundary checks.

checks have never been updated, however, leading to pointless

[psaux] Fix closepath (#55414).

All of the Type 1 path building is done with code common to the

revised CFF engine, with the exception of closepath, which was still
|
||
calling ps_builder_close_contour(), thus previously cached segments

were not always written to the path, and glyph corruption, or even

invalid outlines were possible.

Fix handling of `FT_Bool'.
|
||
|
||
Before this commit we had code like
|
||
|
||
(FT_Bool)( globals->glyph_styles[gindex] & 0x8000)
|
||
|
||
Since `FT_Bool' is defined to be an `unsigned char', the code
|
||
evaluated to something like
|
||
|
||
(unsigned char)( 0x8532 & 0x8000)
|
||
|
||
which in turn expanded to
|
||
|
||
(unsigned char)( 0x8000)
|
||
|
||
and finally yielded 0x00 – i.e., false – not as expected.

Improve auto-hinter handling of bitmap fonts (#54681).
|
||
|
||
For bitmap fonts, `FT_Load_Glyph' should either return an error or
|
||
not set the format to `FT_GLYPH_FORMAT_OUTLINE'. However, in this
|
||
case `FT_Load_Glyph' calls into the auto-hinter which calls back
|
||
into `FT_Load_Glyph' with `FT_LOAD_NO_SCALE' in the flags, which
|
||
marks the glyph as `FT_GLYPH_FORMAT_OUTLINE' with an empty path
|
||
(even though it doesn't have any path). It appears that the
|
||
auto-hinter should not be called when the face doesn't have
|
||

`FT_Load_Glyph' checks whether the driver supports scalable

[pcf] Replace charmap implementation.

PCF comes with charmap lookup table, aka PCF encodings. Using it

[base] Fix mono bitmap presetting (#53896).
|
||
|
||
It is rather fundamental to set monochrome bitmap based on rounded
|

CBox because the b/w rasterizer turns on pixels when their centers are

||
inside the glyph outline. The dropout control is unpredictable and can

distort narrow glyphs if the bitmap is too wide.

[sfnt] Preliminary support of colored layer outlines (#44689).
|
||
|
||
This commit enables OpenType's COLR/CPAL table handling; a typical
|
||
application are color emojis that can be scaled to any size.
|
||
|
||
If the color palette does not exist or is invalid, the rendering
|
||
step rasterizes the outline instead. The current implementation
|
||
assumes that the foreground is black.
|
||
|
||
Enable this by defining option TT_CONFIG_OPTION_COLOR_LAYERS.
|
||
|
||
There are still some issues with metrics; additionally, an API to
|
||
fetch color layers is missing.

Fix DLL compilation on Solaris.
|
||
|
||
AC_COMPILE_IFELSE only tries to compile a `*.c' to a `*.o'. The
|
||
Solaris Studio 12.1 through 12.5 compilers see the
|
||
`-fvisibility=hidden' flag, but ignore it with a warning of:
|
||
|
||
cc: Warning: Option -fvisibility=hidden passed to ld,
|
||
if ld is invoked, ignored otherwise
|
||
|
||
AC_LINK_IFELSE does the compile and then tries to link the result,
|
||
at which point the Solaris linker will issue an error:
|
||
|
||
ld: fatal: option '-fvisibility=hidden' is incompatible with
|
||
building a dynamic executable
|
||
|
||
If we don't use AC_LINK_IFELSE to catch the error, then configure
|
||
will fail further tests which attempt to link, such as those testing
|
||
dependencies like `libbz2'.
|
||
|
||
Also, don't try adding `-fvisibility' if we have already added
|
||
`-xldscope', just use one of them, since Sun Studio 12 and earlier
|
||
compilers only issue a warning, and don't try passing through to the
|
||
linker to generate an error, so AC_LINK_IFELSE doesn't catch them.
|
||
|
||

[cmake] Allow using project as subfolder in other project.
|
||
|
||
* CMakeLists.txt: Test for CMake build directory being different
|
||
from source directory. Provide other parts of the build system
|
||
access the full include directory.

[build] Suppress configure's `nothing to be done' message.
|
||
|
||
This is due to calling the configure script via `make' (within the
|
||
top-level `configure' wrapper script). The same can happen for all
|
||
other secondary make targets that are used to only modify the
|
||
primary one, e.g., `make setup devel'.
|
||
|
||
* builds/dos/detect.mk (emx, turboc, watcom, borlandc, borlandc16),

|
||
(visualc, watcom, visualage, lcc, mingw32, bcc32, devel-bcc,
|
||
devel-gcc): Use no-op recipe.

|
||
Reported by Kiyoshi Kanazawa:
|
||
https://lists.gnu.org/archive/html/freetype-devel/2018-05/msg00008.html
|
||
Thanks to the suggestions by Alexei and Alan Coopersmith.
|
||
|
||
* builds/unix/configure.raw: Check if "-xldscope=hidden" is
|
||
accepted, and if so, it is added to CFLAGS. This is the option
|
||
making Sun / Oracle C compilers hide the symbols from global
|
||
scope.
|
||
* include/freetype/config/ftconfig.h: Use "__global" prefix
|
||
for FT_EXPORT() macro, if SunPro C is newer than Sun ONE
|
||
Studio 8 (2003).
|
||
* builds/unix/ftconfig.in: Ditto.
|
||
* builds/vms/ftconfig.h: Ditto.

|
||
|
||
Unbreak CMake Windows installation
|
||
|
||
* CMakeLists.txt: Generate ftconfig.h on non-UNIX.
|
||
|
||
2018-05-02 Werner Lemberg <wl@gnu.org>
|
||
|
||
Remove FT_CONFIG_OPTION_PIC and related code.
|
||
|
||
*/* [FT_CONFIG_OPTION_PIC]: Remove all code guarded by this
|
||
preprocessor symbol.
|
||
|
||
*/*: Replace `XXX_GET' macros (which could be either a function in
|
||
PIC mode or an array in non-PIC mode) with `xxx' arrays.
