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
#include FOO_H
with
#include <freetype/foo.h>
or something similar. Also update the documentation.
These have not been used in a very, very long time, so better remove
them. A corresponding patch will be submitted to the
`freetype2-demos' repository.
* src/Jamfile, src/*/Jamfile, Jamrules: Delete.
The LCD modules were never truly independent. They mostly served as
a way to disable patented LCD rendering, which is no longer necessary.
The `smooth' module now handles LCD modes as well.
* src/smooth/ftsmooth.c (ft_smooth_lcd_renderer_class.
ft_smooth_lcdv_renderer_class): Deleted.
(ft_render_smooth): Reworked from `ft_render_smooth_generic'.
* src/smooth/ftsmooth.h: Remove dedicated LCD classes.
* src/smooth/module.mk: Remove dedicated LCD modules.
* include/freetype/config/ftmodule.h: Ditto.
* builds/amiga/include/config/ftmodule.h: Ditto.
* include/freetype/ftmodapi.h: Do not mention LCD modules.
The libs which cmake controls are commented out at
include/freetype/config/ftoption.h
and cmake un-comment each enabled library, but the brotli option was
not commented out, therefore `FT_CONFIG_OPTION_USE_BROTLI' remained
defined even if brotli was missing/disabled/etc.
Comment it such that cmake can control it, which means leaving it
undefined if brotli is missing.
* include/freetype/config/ftoption.h: Fix typo.
Brotli is required for decompressing WOFF2 font directory streams.
The library is thus being added as an optional dependency for
FreeType.
* builds/unix/configure.raw: Add checks for `libbrotlidec'.
(REQUIRES_PRIVATE, LIBS_PRIVATE, LIBSSTATIC_CONFIG): Updated.
* devel/ftoption.h, include/freetype/config/ftoption.h
(FT_CONFIG_OPTION_USE_BROTLI): New macro.
We no longer use predefined _DLL, which can be defined for static
builds too with /MD. We use DLL_EXPORT and DLL_IMPORT instead,
following libtool convention.
* CMakeLists.txt [WIN32], builds/windows/vc2010/freetype.vcxproj:
Define DLL_EXPORT manually.
* include/freetype/config/ftconfig.h, builds/unix/ftconfig.in,
builds/vms/ftconfig.h, builds/windows/vc2010/index.html,
src/base/ftver.rc: /_DLL/d, s/FT2_DLLIMPORT/DLL_IMPORT/.
This second and final monster commit was created by applying Nikhil's
scripts `docconverter.py' and `markify.py' to all C header and source files,
followed up by minor manual clean-up.
No change in functionality, of course.
I used commit f7419907bc6044b9b7057f9789866426c804ba82 from
https://github.com/nikramakrishnan/freetype-docs.git.
* include/freetype/config/ftheader.h (FT_COLOR_H): New macro.
* include/freetype/internal/ftobjs.h (FT_Colr_Internal): Change
type of `load_flags' to `FT_Int32'.
* include/freetype/internal/sfnt.h (TT_Load_Colr_Layer_Func): Change
type of `idx' to `FT_UInt'.
(TT_Blend_Colr_Func): Change type of `color_index' to `FT_UInt'.
* src/base/ftobjs.c (FT_Render_Glyph_Internal): Change type of
`load_flags' to `FT_Int32'.
* src/sfnt/ttcolr.c (find_base_glyph_record,
tt_face_load_colr_layers): Change type of `glyph_id' to `FT_UInt'.
(tt_face_find_color, tt_face_colr_blend_layer): Change type of
`color_index' to `FT_UInt'.
Fix signedness and type issues.
* src/sfnt/ttcolr.h: Updated.
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.
* devel/ftoption.h, include/freetype/config/ftoption.h
(TT_CONFIG_OPTION_COLOR_LAYERS): New macro.
* include/freetype/internal/ftobjs.h (FT_Glyph_LayerRec,
FT_Colr_InternalRec): New structures.
(FT_Slot_InternalRec): Add `color_layers' field.
* include/freetype/internal/sfnt.h (TT_Load_Colr_Layer_Func,
TT_Blend_Colr_Func): New function types.
(SFNT_Interface): Add `load_colr', `free_colr', `load_colr_layer',
and `colr_blend' fields.
* include/freetype/internal/tttypes.h (TT_FaceRec): Add
`colr_and_cpal' field.
* include/freetype/internal/tttags. (TTAG_COLR, TTAG_CPAL): New
macros.
* src/sfnt/ttcolr.c, src/sfnt/ttcolr.h: New files.
* src/base/ftobjs.c (ft_glyphslot_done, FT_Render_Glyph_Internal):
Handle glyph color layers.
* src/sfnt/Jamfile (_sources), src/sfnt/rules.mk (SFNT_DRV_SRC): Add
`ttcolr.c'.
* src/sfnt/sfdriver.c: Include `ttcolr.h'.
(PUT_COLOR_LAYERS): New macro.
Update call to `FT_DEFINE_SFNT_INTERFACE'.
* src/sfnt/sfnt.c: Include `ttcolr.c'.
* src/sfnt/sfobjs.c (sfnt_load_face): Load `COLR' and `CPAL' tables.
(sfnt_done_face): Updated.
* src/truetype/ttgload.c (TT_Load_Glyph): Handle color layers.

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.
*/* [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.
* include/freetype/internal/ftpic.h, src/autofit/afpic.c,
src/autofit/afpic.h, src/base/basepic.c, src/base/basepic.h,
src/base/ftpic.c, src/cff/cffpic.c, src/cff/cffpic.h,

src/sfnt/sfntpic.c, src/sfnt/sfntpic.h, src/smooth/ftspic.c,
src/smooth/ftspic.h, src/truetype/ttpic.c, src/truetype/ttpic.h:
Removed.
It is now widely recommended that ELF shared libraries hide symbols
except those with explicit __attribute__((visibility("default"))).
This is supported by all major compilers and should rather be an
option in libtool.
* builds/unix/configure.raw: Add -fvisibility=hidden to CFLAGS.
* builds/unix/ftconfig.in, builds/vms/ftconfig.h,
include/freetype/config/ftconfig.h (FT_EXPORT): Use visibility
attribute.
This reduces redundancy and increases synergy; it also reduces the
number of header files.
* include/freetype/config/ftheader.h (FT_DRIVER_H): New macro.
(FT_AUTOHINTER_H, FT_CFF_DRIVER_H, FT_TRUETYPE_DRIVER_H,
FT_PCF_DRIVER_H, FT_TYPE1_DRIVER_H): Make them aliases to
FT_DRIVER_H.
* include/freetype/ftautoh.h, include/freetype/ftcffdrv.h,
include/freetype/ftpcfdrv.h, include/freetype/ftt1drv.h,
include/freetype/ftttdrv.h: Replaced with...
* include/freetype/ftdriver.h: ...this new file.
(FT_CFF_HINTING_ADOBE, FT_T1_HINTING_ADOBE): Renamed to...
(FT_HINTING_ADOBE): ... this new macro.
(FT_CFF_HINTING_FREETYPE, FT_T1_HINTING_FREETYPE): Renamed to...
(FT_HINTING_FREETYPE): ... this new macro.
* src/*/*: Updated accordingly.
* builds/unix/configure.raw (ftoption_set, ftoption_unset): New
auxiliary functions to construct...
(FTOPTION_H_SED): ... this new variable.
Apply it as a sed argument while copying `ftoption.h' to the
`builds/unix' directory (using `AC_CONFIG_FILES').
Simplify code of test that checks cpp's computation of bit length
(the test previously created an empty `ftoption.h' file and deleted
it immediately afterwards); without this change, it can happen on my
GNU/Linux box that `configure's execution of `config.status' doesn't
create `ftoption.h' (no idea why this happens).
* builds/unix/install.mk (install): Install
`builds/unix/ftoption.h'.
* builds/unix/unix-def.in (DISTCLEAN): Updated.
* builds/unix/.gitignore: Updated.
This controls whether the old Type 1 engine gets compiled into FreeType.
It is disabled by default.
* devel/ftoption.h, include/freetype/config/ftoption.h
(T1_CONFIG_OPTION_OLD_ENGINE): New macro.
* include/freetype/internal/psaux.h (PS_Decoder): Remove unused field.
* include/freetype/internal/psaux.h, src/cid/cidgload.c
(cid_load_glyph), src/psaux/psauxmod.c, src/psaux/psobjs.c
(ps_builder_add_point), src/psaux/t1decode.c
(t1_lookup_glyph_by_stdcharcode, t1_decoder_parse_glyph,
t1operator_seac, t1_decoder_parse_charstrings), src/psaux/t1decode.h,
src/type1/t1gload.c (T1_Parse_Glyph_And_Get_Char_String): Surround
relevant code with macro.
Minor code changes.
