* include/freetype/freetype.h (FREETYPE_MINOR): Set to 10.
(FREETYPE_PATCH): Set to 0.
* builds/unix/configure.raw (version_info): Set to 23:0:17.
* CMakeLists.txt (VERSION_MINOR): Set to 10.
(VERSION_PATCH): Set to 0.
* builds/toplevel.mk (version, winversion): Since the minor version
number has two digits now, never omit the patch number. We would
get ambiguous zip file names otherwise.
(dist): Remove remnants of `docmaker' tool.
(do-dist): Remove unused intermediate files.
* src/cff/cffparse.c (destrict_c2s_item): Guard function with
CFF_CONFIG_OPTION_OLD_ENGINE macro.
This change should allow Freetype to work on WASM/Emscripten without
needing `-s EMULATE_FUNCTION_POINTER_CASTS=1'.
* src/autofit/afdummy.c (af_dummy_hints_apply): Fix signature.
* src/cid/cidload.c (cid_parse_font_matrix, parse_fd_array,
parse_expansion_factor, parse_font_name): Return `void', not
`FT_Error'.
* include/freetype/internal/ftobjs.h (FT_CMap_CharVarIsDefaultFunc):
Fix signature.
* src/psaux/psintrp.c (cf2_interpT2CharString): The call to
`cf2_arrstack_setCount' may fail because the allocator ran out of
memory. When this happens the stack is still written to before the
error condition is checked. This means that FreeType writes outside
of allocated memory. This commit moves the error check prior to the
stack assignment, hence the function now properly returns with an
error condition.
Instead of setting typo or win metrics as the new FT_Face metrics
indiscriminately, apply only typo deltas to the currently active FT_Face
metrics. This prevents line height differences when e.g. the default
outlines were used as the regular face and instances for everything else.
* src/truetype/ttgxvar.c (tt_apply_mvar): Implement.
If the OS/2 table exists and fsSelection bit 7 (USE_TYPO_METRICS) is set,
use the sTypo* set of values to compute the FT_Face's ascender, descender
and height. Otherwise, fall back to old behavior.
* src/sfnt/sfobjs.c (sfnt_load_face): Implement.
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.
* src/psauc/psinterp.c (cf2_interpT2CharString) <cf2_cmdCLOSEPATH>:
Switch to calling `cf2_glyphpath_closeOpenPath'.
For multiple master fonts, common usage (in Postscript) is to modify
the WeightVector of an existing font instance, this addition
supports that use.
* include/freetype/ftmm.h, src/base/ftmm.c (FT_Set_MM_WeightVector,
FT_Get_MM_WeightVector): New API functions.
* include/freetype/internalservices/svmm.h
(FT_Set_MM_WeightVector_Func, FT_Get_MM_WeightVector_Func): New
function types.
(MultiMasters): Add `set_mm_weightvector' and `get_mm_weightvector'
members.
(FT_DEFINE_SERVICE_MULTIMASTERSREC): Updated.
* src/cffcffdrivr.c (cff_set_mm_weightvector,
cff_get_mm_weightvector): New functions.
(cff_service_multi_masters): Register them.
* src/truetype/ttdriver.c (tt_service_gx_multi_masters): Updated.
This driver doesn't use the new interface.
* src/type1/t1load.c (T1_Set_MM_WeightVector,
T1_Get_MM_WeightVector): New functions.
* src/type1/t1driver.c (t1_service_multi_masters): Register them.
* src/type1/t1load.h: Updated.
The solution and project files should be automatically upgraded for
the approriate Visual C++ version.
* builds/windows/visualc/freetype.{sln,vcproj}: Major upgrades.
* builds/windows/visualc/index.html: Document the change.
* builds/windows/vc2005, builds/windows/vc2008: Removed as redundant.
It's been more than 2^31 seconds since 1904.
* include/freetype/tttables.h (TT_Header): Change field types.
* src/sfnt/ttload.c (tt_face_load_generic_header): Updated.
This is a follow-up to the previous commit.
* src/cff/cffobjs.c (cff_face_init), src/sfnt/sfobjs.c
(sfnt_load_face), src/type1/t1objs.c (T1_Face_Init),
src/type42/t42objs.c (T42_Face_Init): Implement it.
* include/freetype/ftsystem.h: Include FT_TYPES_H.
(*FT_Alloc_Func, *FT_Realloc_Func): Use size_t for the size arguments.
* src/raster/ftmisc.h: Ditto.
* builds/amiga/src/base/ftsystem.c, builds/unix/ftsystem.c,
* builds/vms/ftsystem.c, src/base/ftsystem.c (ft_alloc, ft_realloc):
Use size_t for the size arguments.
* src/base/ftdbgmem.c (ft_mem_debug_alloc, ft_mem_debug_realloc): Use
FT_Offset, aka size_t, for the size arguments.
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.
Problem reported and analyzed by Tony Smith <tony.smith@macro4.com>.
* include/freetype/fttypes.h (FT_BOOL): Add a comparison against
zero so that we always have a Boolean expression.
*/*: Replace castings to `FT_Bool' with calls to `FT_BOOL' where
possible.
This makes FT_Get_Char_Index and FT_Get_Next_Char 4-5 times faster.
* src/bdf/bdfdrivr.c (bdf_cmap_char_{index,next}): Help binary search
with continuous prediction.
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 if 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
scalable outlines.
PCF comes with charmap lookup table, aka PCF encodings. Using it
directly makes FT_Get_Char_Index and FT_Get_Next_Char 4-5 times
faster than the original BDF-like binary searches.
* src/pcf/pcf.h (PCF_EncodingRec): Removed.
(PCF_FaceRec): Remove `nencodings' and `encodings'.
* src/pcf/pcfdrivr.c (pcf_cmap_char_{index,next}): Replaced.
* src/pcf/pcfread.c (pcf_get_encodings): Store data differently.
* src/pcf/pcf.h (PCF_Face): Updated to include...
(PCF_EncRec): ... this new structure to store charmap geometry.
* src/pcf/pcfread.c (pcf_get_encodings): Store charmap geometry.

https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=10317
* src/truetype/ttgxvar.c (ft_var_load_gvar): Properly exit memory
frame if we have invalid glyph variation data offsets.
(tt_face_vary_cvt): Protect against missing `tuplecoords' array.
Fix typo.
* src/sfnt/sfdriver (IS_WIN, IS_APPLE): Omit language ID checks.
(get_win_string, get_apple_string): Return NULL when the PostScript
font name characters is not according to specification.
(get_win_string): Make trace output work if the high byte if
non-zero.
(sfnt_get_var_ps_name, sfnt_get_ps_name): Previously we preferred
Win PS name (when there is also an Apple PS name); change this into
a fallback to Apple PS name in case the Win PS name is invalid.
These public API functions(!) were always undocumented and have
escaped all clean-up efforts until now.
* include/freetype/ftoutln.h (FT_Outline_New_Internal,
FT_Outline_Done_Internal): Removed.
* src/base/ftoutln.h (FT_Outline_New_Internal,
FT_Outline_Done_Internal): Merge into...
(FT_Outline_New, FT_Outline_Done): ... these functions.
* docs/README: Updated.
* include/freetype/fterrors.h (FT_INCLUDE_ERR_PROTOS,
FT_ERR_PROTOS_DEFINED): Undefine `FT_INCLUDE_ERR_PROTOS' after
checking it and introduce a new macro that takes proper care of
multiple-inclusion protection.
* include/freetype/internal/ftobjs.h (ft_glyphslot_preset_bitmap):
Change return type.
* src/base/ftobjs.c (ft_glyphslot_preset_bitmap): Return the bitmap
size assessment.
* src/raster/ftrend1.c (ft_raster1_render): Use it to refuse the
rendering of enourmous or far-fetched outlines.
* src/smooth/ftsmooth.c (ft_smooth_render_generic): Ditto.
