2021-07-12 David Turner <david@freetype.org>
|
||
|

Remove obsolete `AF_Angle` type and related sources.
|
||
|
||
* src/autofit/afangles.c: File removed. Functions related to
|

|
||
|
||
Remove experimental auto-hinting 'warp' mode.
|
||
|
||
This feature was always experimental, and probably never worked
|
||
properly. This patch completely removes it from the source code,
|
||
except for a documentation block describing it for historical
|
||
purposes.
|
||
|
||
* devel/ftoption.h, include/freetype/config/ftoption.h: Remove
|
||
`AF_CONFIG_OPTION_USE_WARPER`.
|
||
|
||
* include/freetype/ftdriver.h: Document 'warping' property as
|
||
obsolete.
|
||
|
||
* src/autofit/afwarp.c, src/autofit/afwarp.h: Files removed.
|
||
* src/autofit/*: Remove any code related to warp mode.
|
||
|
||
2021-07-12 David Turner <david@freetype.org>
|
||
|
||
Remove experimental 'Latin2' writing system (`FT_OPTION_AUTOFIT2`).
|
||
|
||
This code has always been experimental and was never compiled anyway
|
||
(`FT_OPTION_AUTOFIT2` does not appear in `ftoption.h` or even any of
|
||
our build files).
|
||
|
||
* include/freetype/internal/fttrace.h (aflatin2): Removed.
|
||
* src/autofit/aflatin2.h, src/autofit/aflatin2.c: Files removed.
|
||
* src/autofit/afloader.c: Remove undocumented hook to activate
|
||
Latin2 system.
|
||
* src/autofit/afstyles.h: Remove `ltn2_dflt` style definition.
|
||
* src/autofit/afwrtsys.h: Remove `LATIN2` writing system definition.
|
||
* src/autofit/autofit.c: Updated.

|
||
|
||
Reported by Hin-Tak.
|
||
|
||
2021-07-03 Werner Lemberg <wl@gnu.org>
|
||
|
||
* meson_options.txt: Sort alphabetically; no final full stops.
|
||
|
||
2021-07-01 Ben Wagner <bungeman@chromium.org>
|
||
|
||
* src/truetype/ttgxvar.c (tt_set_mm_blend): Test `coords`.
|
||
|
||
It is undefined behavior to pass `NULL` to `memcpy`. `coords' is
|
||
passed to `memcpy` but `TT_Get_MM_Blend` and `TT_Get_Var_Design`
|
||
explictly call `tt_set_mm_blend` with `coords` as `NULL`. In
|
||
addition, `TT_Set_MM_Blend` has a similar possible issue.

[sfnt] Support PaintScale in 'COLR' v1 parsing.
|
||
|
||
* include/freetype/ftcolor.h (FT_PaintFormat): Renumber values, add
|

`FT_COLR_PAINTFORMAT_SCALE`.
|

[sfnt] Handle fonts without layer list in 'COLR' v1.
|
||
|
||
'COLR' v1 fonts do not necessarily need to have a layer list; for
|
||
this reason, 'fontTools' recently started generating fonts in a way
|
||
that drops the layer list if there are no layers in it. This
|
||
results in the layer list offset becoming zero, which FreeType
|
||
treated as an invalid table. Fix that and handle the case for layer
|
||
list offset being 0. This slightly changes how we need to calculate
|
||
the starting offset for paints.
|
||
|
||
* src/sfnt/ttcolr.c (tt_face_load_colr): Handle case of layer list
|
||
offset being zero without outright rejecting table.
|
||
|
||
2021-06-30 Alexei Podtelezhnikov <apodtele@gmail.com>

||
|
||
2021-06-29 Alexei Podtelezhnikov <apodtele@gmail.com>
|
||
|
||
[raster] Do not skip the second pass without dropout control.
|
||
|
||
The second pass also fixes horizontal lines through the pixel centers.
|
||
|
||
* src/raster/ftraster.c (black_TWorker): Do not use `second_pass'.
|
||
(Render_Glyph): Skip the second pass only with the appropriate flag.
|
||
|
||
2021-06-29 Alexei Podtelezhnikov <apodtele@gmail.com>
|
||
|

[raster] Handle sub-band stack locally.
|
||
|
||
* src/raster/ftraster.c (black_TWorker): Move `band_stack' from here..
|
||
(Render_Single_Pass): ... to here and accept limit arguments.
|

(Render_Glyph): Updated.

||
|
||
[sfnt] Improve paint limit checks
|
||
|
||
Paint tables can appear before the `base_glyphs_v1` offset if the
|
||
font is produced with the layer list before the base glyph list. In
|
||
this case paint tables can occur after the layer list but before the
|
||
base glyph list. Checks in the 'COLR' v1 code were rejecting fonts
|
||
with this layout. Improve these checks by calculating a minimum
|
||
offset after which paint tables can occur and use that in safety
|
||
checks.
|
||
|
||
* src/sfnt/ttcolr.c (Colr, tt_face_load_colr): Declare
|
||
`paint_start_v1` and calculate that as the minimum of the end of
|
||
layer list and base glyph list.
|
||
(get_child_table_pointer, read_paint, tt_face_get_paint_layers):
|
||
Use that in safety checks.
|
||
|
||
2021-06-28 Alexei Podtelezhnikov <apodtele@gmail.com>
|
||
|
||
[raster] Clean up vertical sweep.
|
||
|
||
* src/raster/ftraster.c (black_TWorker): Replace the current line
|
||
offset with the pointer and drop the increment.
|
||
(Function_Sweep_Init): Take values as arguments instead of pointers.
|
||
(Vertical_Sweep_*, Horizontal_Sweep_Init, Draw_Sweep): Updated.
|
||
|
||
2021-06-25 Alexei Podtelezhnikov <apodtele@gmail.com>
|
||
|
||
[raster] Make `band_top' local variable.
|
||
|
||
* src/raster/ftraster.c (black_TWorker): Move `band_top' from here...
|
||
(Render_Single_Pass): ... to here, and refactor.
|
||
(Render_Glyph): Updated.
|
||
|
||
2021-06-25 Alexei Podtelezhnikov <apodtele@gmail.com>
|
||
|
||
[raster] Adjust sub-band bisecting limits.
|
||
|
||
We can bisect a band until it is just a single scan line. This might
|
||
be slow and cause time-outs but if we need to impose limits it should
|
||
be elsewhere.
|
||
|
||
* src/raster/ftraster.c (Render_Single_Pass): Tweak sub-banding.
|
||
|

2021-06-25 Alexei Podtelezhnikov <apodtele@gmail.com>

[base] Add trace level to logging output.
|
||
|
||
Some practical debugging work has shown that displaying level X of
|
||
an `FT_TRACEX` macro in the output of `FT2_DEBUG="... -v"` would be
|
||
very helpful to find out which trace level should be selected. As
|
||
an example, we now get output like
|
||
|
||
```
|
||
[ttobjs:2] TTF driver
|
||
[ttobjs:2] SFNT driver
|
||
[sfobjs:2] not a font using the SFNT container format
|

```
|
||
|
||
* include/freetype/internal/ftdebug.h (FT_LOGGING_TAGX): New macro.

Adjust.

[smooth, raster] Fix up and align error codes.
|
||
|
||
FT_Render_Glyph picked up FAILURE or 1 returned from the raster
|
||
function, which became a confusing error code. Instead, return
|
||
Raster_Overflow in the unlikely event that banding does not help or
|
||
another meaningful error.
|
||
|
||
* src/smooth/ftgrays.c (gray_convert_glyph_inner, gray_convert_glyph):
|
||
Use Raster_Overflow when the rendering pool is exhausted and return it
|
||
if banding does not help.
|
||
(gray_raster_render): Use Smooth_Err_Ok.
|
||
|
||
* src/raster/ftraster.c (Render_Single_Pass): Return Raster_Overflow
|

if banding does not help or another error code.

[smooth, raster] Remove synonymous error macros.
|

(gray_convert_glyph_inner): Updated accordingly.
|

(New_Profile, End_Profile, Insert_Y_Turn, Line_Up, Bezier_Up,

Decompose_Curve, Draw_Sweep, Render_Single_Pass, ft_black_render):

successful, but -1 is still returned by the function. The fix is to

set `error` to 0 appropriately.

[sdf] Use 8 bits for final SDF output instead of 16bits.

Since 8-bits is enough to represent SDF data we no longer require

16-bits for this purpose. Also, we now normalize the output data
|

to use the entire 8-bit range efficiently. For example: if we use

3.5 format with a spread of 1 we basically only use the starting

5-bits. By normalizing we can use the entire 8-bit range.

[CMake] Update dependency finders.
|

1. Fixes CMake using any found HarfBuzz version lower than the minimum

required. This is based on HALX99's merge request at

||
https://gitlab.freedesktop.org/freetype/freetype/-/merge_requests/31
|
||
2. Update FindHarfBuzz.cmake from
|

https://github.com/WebKit/WebKit/blob/1ce32454/Source/cmake/FindHarfBuzz.cmake
|
||
and guard post-CMake-3.1 features to keep the minimum version unchanged
|
||
3. Update FindBrotliDec.cmake to stop the warnings, based on what
|
||
https://github.com/google/woff2/blob/a0d0ed7d/cmake/FindBrotliDec.cmake
|
||
is doing

[gzip] Use exact type for `ft_gzip_alloc` and `ft_gzip_free`.
|
||
|
||
While a function pointer may be cast to another function pointer
|
||
type, it is required to cast the function pointer back to the
|
||
original function pointer type before calling it. If a parameter is
|
||
a pointer the exact pointer type is required. Using a pointer to a
|
||
different underlying type is technically undefined behavior. The
|
||
wrapper functions `ft_gzip_alloc` and `ft_gzip_free` took
|
||
`FT_Memory` (a `FT_MemoryRec_*`) instead of `voidpf` (`void*`), so
|
||
when gzip calls these callbacks through `alloc_func` or `free_func`
|
||
it invokes undefined behavior. On most platforms this works out as
|
||
expected, but newer undefined behavior detectors and targets like
|
||
wasm can detect this and will produce an error.
|
||
|
||
* src/gzip/ftgzip.c (ft_gzip_alloc, ft_gzip_free): Update signatures
|
||
to exactly match `alloc_func` and `free_func`, respectively.
|
||
Internally, cast the `void*` opaque pointer to `FT_Memory`.

[smooth] Faster bitmap sweeping.
|
||
|
||
Selecting the fill rule or checking the direct mode each time we call

* src/smooth/ftgrays.c (gray_hline): Eliminated in favor of...

[base] Complete `ft_glyphslot_clear`.
|
||
|

* src/base/ftobjs.c (ft_glyphslot_clear): This function is intended
|
||
to reset all the values of a glyph slot. However, it was not
|
||
resetting the values of the advances and `glyph_index`. Reset the
|
||
advances and `glyph_index` to zero.

2021-04-02 Ben Wagner <bungeman@chromium.org>

||
|
||
[truetype] Prevent glyph program state from persisting.
|
||
|
||
`FDEF` instructions are specified as allowed only in 'prep' or
|
||
'fpgm'. FreeType has attempted to prevent their use in the glyph
|
||
program, but they were still allowed in glyph programs if defined in
|
||
a function defined in 'prep' or 'fpgm' and called from the glyph
|
||
program.
|
||
|
||
Similarly, `IDEF` instructions are specified not to be able to
|
||
modify any existing instruction. FreeType has attempted to prevent
|
||
their use in the glyph program, but they can still be used like
|
||
`FDEF`.
|
||
|
||
This change stores the initial bytecode range type and disallows the
|
||
use of `FDEF` and `IDEF` while running the glyph program.
|
||
|
||
Most other state is copied from the `TT_Size` into the execution
|
||
context. However, it is possible for a glyph program to use `WS` to
|
||
write to the storage area or `WCVTP`, `WCVTF`, and `DELTAC[123]` to
|
||
write to the control value table.
|
||
|
||
Allowing any change to the global state from the glyph program is
|
||
problematic as the outlines of any given glyph may change based on
|
||
the order the glyphs are loaded or even how many times they are
|
||
loaded. There exist fonts that write to the storage area or the
|
||
control value table in the glyph program, so their use should not be
|
||
an error.
|
||
|
||
Possible solutions to using these in the glyph program are
|
||
|
||
* ignore the writes;
|
||
* value-level copy on write, discard modified values when finished;
|
||
* array-level copy on write, discard the copy when finished;
|
||
* array-level copy up-front.
|
||
|
||
Ignoring the writes may break otherwise good uses. A full copy
|
||
up-front was implemented, but was quite heavy as even well behaved
|
||
fonts required a full copy and the memory management that goes along
|
||
with it. Value-level copy on write could use less memory but
|
||
requires a great deal more record keeping and complexity. This
|
||
change implements array-level copy on write. If any attempt is made
|
||
to write to the control value table or the storage area when the
|
||
initial bytecode range was in a glyph program, the relevant array
|
||
will be copied to a designated storage area and the copy used for
|
||
the rest of the glyph program's execution.

Reported as

|
||
|
||
Memory is allocated and the pointer assigned to `rows` inside a
|
||
'setjmp' scope. This memory must be freed outside the 'setjmp'
|
||
scope after a 'longjmp'. Since `rows` is a local and modified
|
||
inside the 'setjmp' scope it must be marked volatile or it will have
|
||
an indeterminate value after the 'longjmp'.

* builds/toplevel.mk: Avoid side effects of `shell`.
|
||
|

We use a dummy variable to catch its output. Otherwise the `make`

Move 'dlg' submodule to `subprojects` directory.
|

|

This is for future changes with Meson, which doesn't allow a

Many projects (e.g., fontconfig, cairo) hardcode the `freetype_dep`

variable name to use FreeType as subproject because that was the

should stop hardcoding that variable name, it does not cost us

anything to keep using that name to ease transition.

Meson will still fall back to HarfBuzz subprojects if the `harfbuzz`
|
||
option is set to `enabled` instead of `auto` and a
|
||
`subprojects/harfbuzz.wrap` file is present. In that case it is the
|
||
responsibility of the main project to set the proper options on each
|
||
subproject to break the dependency cycle.
|
||
|
||
Fixes: #1028.

[meson] Fix dependency lookup and generate `ftconfig.h`.
|
||
|
||
- zlib: If not found on the system, meson can build it as a
|
||
subproject. We thus never use the (outdated) zlib support that
|
||
comes with FreeType. Doing so has the additional advantage that
|
||
the zlib code can be shared with other projects like GLib if both
|
||
are subprojects of an application.
|
||
- harfbuzz: Build as a subproject if not found on the system.
|
||
- 'QUESTION: What if the compiler doesn't support `-D` but uses `/D`
|
||
instead as on Windows?' Answer: Meson translate arguments for us.
|
||
- visibility: Replace self-made code with meson-specific solution.
|
||
|

||
* meson.build: Fix resource compilation on Windows.
|
||
|
||
This is copied from GStreamer's meson port of FreeType.
|
||
|
||
(ft2_sources): Add both debug and resource file (the latter for
|
||
Windows only).
|
||
(ft2_debug_src): Removed.

|
||
|
||
* meson.build: s/ft2_libtool_version/ft2_pkgconfig_version/.
|
||
|
||
(freetype2_dep): Use it.
|
||
|
||
`ft2_libtool_version` would be the shared library version, not the
|
||
one we should use in file `freetype2.pc`.
|
||
|
||
2021-02-09 Xavier Claessens <xavier.claessens@collabora.com>
|
||
|
||
* meson.build: Use `meson.override_dependency`.
|
||
|
||
This is a new meson mechanism to avoid other projects to hard-code
|
||
the `freetype2_dep` variable name in their build definition. It
|
||
also ensures that meson does not mix system and subproject versions
|
||
of FreeType inside of the same project.
|
||
|
||
Also remove outdated TODO because `declare_dependency` was already
|
||
there.
|
||
|
||
2021-02-09 Xavier Claessens <xavier.claessens@collabora.com>
|
||
|
||
* meson.build (bzip2_dep): Simplify.
|
||
|
||
We remove `static:false` from `find_library('bz2')`.
|
||
|
||
I don't know whether the previous code was a workaround for an old
|
||
meson bug, but at least with version >=0.55.0 (which FreeType uses)
|
||
it picks the shared library when both are available.
|
||
|
||
File `freetype2.pc` still contains the full path to file `libbz2.so`
|
||
instead of `-lbz2` – that we need to do this is a meson bug even
|
||
present in the current version (0.57.0).
|
||
|
||
2021-02-09 Xavier Claessens <xavier.claessens@collabora.com>

|
||
|
||
[base] Allow renderers of different formats.
|
||
|
||
* src/base/ftobjs.c (FT_Render_Glyph_Internal): Do not return if the
|
||
glyph's slot format is `FT_GLYPH_FORMAT_BITMAP`. The forthcoming
|
||
'bsdf' renderer will require bitmaps for processing.
|
||
|
||
* src/base/ftobjs.c (ft_add_renderer, ft_remove_renderer): Remove
|
||
renderer's glyph format check before adding and removing them. The
|
||
'bsdf' renderer will have a format `FT_GLYPH_FORMAT_BITMAP`.
|
||
|
||
2020-08-16 Anuj Verma <anujv@iitbhilai.ac.in>
|
||
|
||
Add data types required for the forthcoming 'sdf' module.
|
||
|
||
* include/freetype/freetype.h (FT_Render_Mode): Add new render mode
|
||
`FT_RENDER_MODE_SDF`, which will be used to generate SDF.
|
||
|
||
* include/freetype/ftimage.h (FT_Pixel_Mode): Add new pixel mode
|
||
`FT_PIXEL_MODE_GRAY16`, which will be the output of the 'sdf'
|
||
module.
|
||
(FT_RASTER_FLAG_SDF): New raster flag to be used internally by the
|
||
'sdf' module.
|
||
|
||
* include/freetype/fttypes.h (FT_F6Dot10): New data type.
|
||
|
||
2020-08-16 Anuj Verma <anujv@iitbhilai.ac.in>
|
||
|
||
[base] Allow renderers of different formats.
|
||
|
||
* src/base/ftobjs.c (FT_Render_Glyph_Internal): Do not return if the
|
||
glyph's slot format is `FT_GLYPH_FORMAT_BITMAP`. The forthcoming
|
||
'bsdf' renderer will require bitmaps for processing.
|
||
|
||
* src/base/ftobjs.c (ft_add_renderer, ft_remove_renderer): Remove
|
||
renderer's glyph format check before adding and removing them. The
|
||
'bsdf' renderer will have a format `FT_GLYPH_FORMAT_BITMAP`.
|
||
|
||
2020-12-23 Werner Lemberg <wl@gnu.org>
|
||
|
||
* builds/windows/detect.mk (COPY): Make it work with `shell`.
|
||
|
||
Without this patch, we get the error
|
||
|
||
builds/toplevel.mk:127: *** missing separator. Stop.
|
||
|
||
Reported by Anuj, with a solution from Alexei.
|
||
|

||
|
||
* meson.build (ft2_defines): Fix builds on Windows.
|
||
|
||
2020-12-18 Tatsuyuki Ishi <ishitatsuyuki@gmail.com>
|
||
|
||
[autofit] Fix double division in stem darkening.
|
||
|
||
The old code used to divide the darkening amount by em_ratio twice,
|
||
leading to unnecessarily bold stems on certain fonts with higher
|
||
units per em (e.g. Inter). This patch fixes it.
|
||
|
||
The return value of af_loader_compute_darkening was also changed to
|
||
use 16.16 fixed point to get rid of a redundant truncation operation.
|
||
This should slightly improve the precision, although it's still
|
||
bottlenecked by the emboldening function, which uses 26.6 fixed point.
|
||
|
||
* src/autofit/afloader.[ch]
|
||
(af_loader_compute_darkening): Return FT_Fixed.
|
||
(af_loader_embolden_glyph_in_slot): Revise calculations.
|
||
|

|
||
|
||
2020-12-16 Chris Liddell <chris.liddell@artifex.com>
|
||
|
||
[truetype] Fix incremental metrics (#59503).
|
||
|
||
* src/truetype/ttgload.c (tt_get_metrics, load_truetype_glyph):
|
||
Previously, the code would populate the phantom points before
|
||
calling the `get_glyph_metrics` callback. For formats like PCL XL
|
||
format 1, class 2 downloaded fonts (where metrics are removed from
|
||
the TTF header), this causes problems when the hinting program uses
|
||
the phantom points (misplaced and distorted glyphs) due to the
|
||
metrics being unset (all zeros).
|
||
(tt_get_metrics_incr_overrides): Renamed to...
|
||
(tt_get_metrics_incremental): ... this. Updated caller
|
||
|
||
* include/freetype/ftincrem.h: Update the documentation to make it
|
||
clearer that `get_glyph_metrics` is to retrieve metrics from a
|
||
non-standard source, but *not* for the purpose of imposing custom
|
||
metrics.
|
||
|
||
2020-12-14 Werner Lemberg <wl@gnu.org>

||
|
||
[dlg] Fix compiler warnings.
|
||
|
||
* src/dlg/dlgwrap.c: Duplicate some feature test macros from

platforms.
|
||
(DisableLanguageExtensions): We need to disable the `/Za` option
|
||
when building 'dlg' with FreeType as 'dlg' strictly follows the C99
|
||
standard. Visual C++ produces behaves unexpectedly when
|
||
compiling a C99 file with `/Za` option enabled.

||
2020-10-26 Werner Lemberg <wl@gnu.org>
|
||
|
||

|
||
* src/sfnt/pngshim.c (Load_SBit_Png): Fix memory leak (#59322).

[autofit] Synchronize with ttfautohint.
|
||
|
||
This corresponds to the following commits in the ttfautohint git
|
||
repository:
|
||
|
||
bb6842bd3bd437b7b4a7921b0376c860f5e73d18 Typo, formatting.
|
||
d5c91ddb1cb310257a3dfe9a8e20e1fc51335faa Add Medefaidrin script.
|
||
|
||
* src/autofit/afblue.dat: Add blue zone data for Medefaidrin.
|
||
* src/autofit/afblue.c, src/autofit/afblue.h: Regenerated.
|
||
|
||
* src/autofit/afscript.h: Add Medefaidrin standard characters.
|
||
|

2020-09-25 Werner Lemberg <wl@gnu.org>
|
||
|
||
Move `scripts/make_distribution_archives.py` to `src/tools`.
|
||
|
||
* scr/tools/scripts/make_distribution_archives.py: (_TOP_DIR,
|
||
_SCRIPT_DIR): Updated to new location.
|
||
(main): s/shutils.copyfile/shutils.copy/ to preserve file
|
||
permissions.
|
||
(main): Prefix source file paths with `git_dir` while copying files
|
||
to allow calls of the script from other places than the top-level
|
||
directory.
|
||
|
||
2020-09-24 Werner Lemberg <wl@gnu.org>
|
||
|
||
* src/cff/cffgload.c (cff_slot_load): Scale `vertBearingY`.
|
||
|
||
Towards the end of the the function there is a call to
|
||
`FT_Outline_Get_CBox` that retrieves the glyph bbox in scaled units.
|
||
That sets `horiBearing{X,Y}` and `vertBearingX` but `vertBearingY`
|
||
is left alone, and is not scaled.
|
||
|
||
Patch from Eric Muller <emuller@amazon.com>.
|
||
|
||
2020-09-24 Werner Lemberg <wl@gnu.org>
|
||
|
||
* src/base/ftobjs.c (FT_Load_Glyph): Trace glyph metrics.

[meson] Move auxiliary scripts to `builds/meson`.
|
||
|
||
Suggested by Alexei.
|
||
|
||
* scripts/*.py: Move meson scripts to...
|
||
* builds/meson/*.py: ... this new location.
|
||
|
||
* meson.build: Updated.
|
||
|
||
2020-09-21 David Turner <david@freetype.org>
|
||
|
||
Add python script for building tarballs.
|
||
|
||
* scripts/make_distribution_archives.py: New file.
|
||
|
||
This standalone Python script should be equivalent to running `make
|
||
dist` with the Make-based build system, with the following minor
|
||
differences:
|
||
|
||
- Since `make distclean` doesn't always clean up `objs/` properly,
|
||
`make dist` archives may contain some stale binaries like
|
||
`objs/.libs/libfreetype.so.6` or others.
|
||
|
||
- `config.guess` and `config.sub` are not updated unless option
|
||
`--gnu-config-dir=DIR` is used to specify the location of these
|
||
files.
|
||
|
||
- Some bits of the auto-generated reference documentation may
|
||
appear in slightly different order, probably due to issues related
|
||
to mkdocs and docwriter.
|
||
|
||
As an example, the call
|
||
|
||
scripts/make_distribution_archives.py /tmp/freetype2-dist
|
||
|
||
creates the following files under `/tmp/freetype2-dist`:
|
||
|
||
freetype-<version>.tar.gz
|
||
freetype-<version>.tar.xz
|
||
ft<winversion>.zip
|
||
|
||
2020-09-21 Werner Lemberg <wl@gnu.org>
|
||
|
||
* scripts/extract_freetype_version.py: Fix regex typos.
|
||
|
||
2020-09-21 David Turner <david@freetype.org>
|
||
|
||
Add Meson build project file.
|
||
|
||
Example usage:
|
||
|
||
# Configure Meson build in directory `build-meson` to generate
|
||
# release binaries comparable to to the ones from the
|
||
# autotools/make build system.
|
||
meson setup build-meson \
|
||
--prefix=/usr/local \
|
||
--buildtype=debugoptimized \
|
||
--strip \
|
||
-Db_ndebug=true
|
||
|
||
# After configuring the Meson build with the above command,
|
||
# compile and install to `/usr/local/`; this includes a pkg-config
|
||
# file.
|
||
ninja -C build-meson install
|
||
|
||
# Alternatively, compile and install to `/tmp/aa/usr/local/...`
|
||
# for packaging.
|
||
DESTDIR=/tmp/aa ninja -C build-meson install
|
||
|
||
# Generate documentation under `build-meson/docs`.
|
||
ninja -C build-meson docs
|
||
|
||
Library size comparison for stripped `libfreetype.so` generated by
|
||
all three build systems:
|
||
|
||
- Default build (autotools + libtool): 712 KiB
|
||
- CMake build (RelWithDebInfo): 712 KiB
|
||
- Meson build: 712 KiB
|
||
|
||
|
||
* meson.build: New top-level Meson build file for the library.
|
||
|
||
* meson_options.txt: New file. It holds user-selectable options for
|
||
the build, which can be printed with `meson configure`, and selected
|
||
at `meson setup` or `meson --reconfigure` time with
|
||
`-D<option>=<value>`.
|
||
|
||
* scripts/parse_modules_cfg.py: A script invoked by `meson.build` to
|
||
parse `modules.cfg` and extract important information out of it
|
||
(i.e., the list of modules).
|
||
|
||
* scripts/process_ftoption_h.py: New script invoked by `meson.build`
|
||
to process the original `ftoption.h` file. It enables or disables
|
||
configuration macro variables based on the available dependencies.
|
||
This is similar to what other build systems are using (i.e., Meson's
|
||
`configure_file()` command is not used here).
|
||
|
||
* scripts/extract_freetype_version.py: New script invoked by
|
||
`meson.build` to extract the FreeType version number from
|
||
`<freetype/freetype.h>`.
|
||
|
||
* scripts/extract_libtool_version.py: New script invoked by
|
||
`meson.build` to extract the libtool `revision_info` data from
|
||
`builds/unix/configure.raw`, and to generate the corresponding
|
||
shared library suffix.
|
||
|
||
* scripts/generate_reference_docs.py: New script invoked by
|
||
`meson.build` to generate the FreeType 2 reference documentation
|
||
(using the `docwriter` and `mkdocs` packages, which must be already
|
||
installed).

[raster] Improve the second pass (#58373).
|
||
|
||
Besides dropout control the second horizontal sweep is supposed to
|
||
clean up straight horizontal edges that are mishandled by the first
|
||
vertical sweep when a line passes through pixel centers. This line
|
||
would present as perfectly aligned span edges in the second sweep.
|
||
|
||
* src/raster/ftraster.c (Horizontal_Sweep_Span): Replace the old
|
||
implementation with a better one focusing on aligned span edges only.

[raster] Tune SMART macro (#58352).
|
||
|
||
Windows seems to perform smart dropout control at 26.6 precision.
|
||
To mimick Windows independent of increased precision, we need to tweak
|
||
the macro so that some close calls break down rather than up.
|
||
|
||
* src/raster/ftraster.c (SMART): Tweak the macro.
|
||
|
||
2020-09-08 Alexei Podtelezhnikov <apodtele@gmail.com>
|
||
|

[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...
|

(FT_EXPORT): Use it.

* include/freetype/config/compiler-macros.h

(FT_INTERNAL_FUNCTION_ATTRIBUTE): New macro to tag functions as

the need to enforce this when invoking the compiler (e.g., with an

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

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>

[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...

2020-07-03 Alexei Podtelezhnikov <apodtele@gmail.com>
|
||
|

[smooth] Use direct rendering mode in Harmony.
|
||
|

direct rendering to deliver the bitmaps on each third byte.

||
|
||
* src/smooth/ftsmooth.c (ft_smooth_raster_lcd)

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...

Make macros for header file names optional.
|

We no longer have to take care of the 8.3 file name limit; this

[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

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

|
||
(compute_ULong_sum): New function. Calculate checksum of table.
|
||
(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.
|
||

`face_index' is now being passed as a parameter to
|

`woff2_open_font'.

|
||
|
||
[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
|
||
`gray_render_cubic', this makes the function faster by 10% and is
|
||
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

index 0, thus increasing the number of glyphs by one (as before).

[cff] Fix boundary checks.

642bc7590c701c8cd35a9f60fa899cfa518b17ff introduced dynamically

checks have never been updated, however, leading to pointless

"new" one.

[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
|
||
outlines. The current test for using the auto-hinter in
|

`FT_Load_Glyph' checks whether the driver supports scalable
|

outlines, but not if the face supports scalable outlines.

* src/base/ftobjs.c (FT_Load_Glyph): Directly check whether we have

[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
|

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'.

|
||
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.
