9817571c	2018-10-03T08:04:55	[ftgrays] Fix typo in stand-alone mode (#54771). * src/smooth/ftgrays.c (FT_THROW) [STANDALONE_ && FT_DEBUG_LEVEL_TRACE]: Fix call to `FT_ERR_CAT'.
d280ae1e	2018-10-02T20:45:16	[psaux] Fix segfault. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=10768 * src/psaux/cffdecode.c (cff_decoder_parse_charstrings) <cff_op_callothersubr> [CFF_CONFIG_OPTION_OLD_ENGINE]: Check argument.
6b660f12	2018-10-02T16:48:59	[psaux] Fix numeric overflow. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=10768 * src/psaux/cffdecode.c (cff_decoder_parse_charstrings) <cff_op_roll> [CFF_CONFIG_OPTION_OLD_ENGINE]: Use NEG_INT.
83fc524d	2018-10-02T16:36:49	[pshinter] Handle numeric overflow. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=10550 * src/pshinter/pshglob.c (psh_blues_snap_stem): Mask numeric overflow.
877aa1b2	2018-09-27T21:17:36	Align FreeType with standard C memory management. * 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.
4500c701	2018-09-26T22:04:50	Typo.
efe7f648	2018-09-25T09:16:45	Typo.
a9af6914	2018-09-25T09:10:09	Fix handing 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. 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.
0f122fef	2018-09-23T21:46:26	[bdf] Speed up charmap access. 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.
793a9ff9	2018-09-22T14:38:00	* src/base/ftobjs.c (ft_glyphslot_reset_bimap): Another tweak. This one should be clearer. When the rounded monochrome bbox collapses we add a pixel that covers most if not all original cbox.
f26d5775	2018-09-21T20:34:58	* src/base/ftobjs.c (ft_glyphslot_reset_bimap): Further tweak.
abd997aa	2018-09-21T12:50:32	Improve documentation of `FT_LOAD_NO_RECURSE'.
335528e1	2018-09-21T11:26:37	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 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.
c168cc3b	2018-09-21T11:09:27	[raster] Fix disappearing vertical lines (#54589). * src/raster/ftraster.c (Vertical_Sweep_Span): Handle special case where both left and right outline exactly pass pixel centers.
493aa68f	2018-09-21T08:32:22	[base] Some comments.
2a9850c4	2018-09-20T22:40:32	* src/base/ftobjs.c (ft_glyphslot_reset_bimap): Tiny rounding tweak. This adds pixels in case a contour goes through the center and they need to be turned on in the b/w rasterizer.
c1b21f47	2018-09-20T22:14:46	[pcf] Replace charmap implementation. 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.
8e950680	2018-09-20T06:26:34	[base] Remove unused function `FT_GlyphLoader_CopyPoints'. * include/freetype/internal/ftgloadr.h, src/base/ftgloadr.c (FT_GlyphLoader_CopyPoints): Do it.
7f93c977	2018-09-19T22:45:45	[pcf] Prepare to replace charmap implementation. * 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.
d629c2ba	2018-09-18T17:11:48	Remove unused fields. * src/pcf.h (PCF_FaceRec): Remove `charmap' and `charmap_handle'. * src/bdfdrvr.h (BDF_FaceRec): Ditto. * src/winfonts/winfnt.h (FNT_FaceRec): Ditto.
dfddc2d9	2018-09-17T08:03:57	[pshinter] Handle numeric overflow. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=10396 * src/pshinter/pshglob.c: Include FT_INTERNAL_CALC_H. (psh_blues_snap_stems): Mask numeric overflow.
b8dd404d	2018-09-16T07:22:23	freetype.h: Add warning w.r.t. B/W hinting and rendering (#54589).
de0aabcd	2018-09-15T06:14:18	[sfnt] Comment fix.
10e54d04	2018-09-13T21:47:35	[truetype] Some fixes for VF checks. Reported as 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.

6b53300b	2018-09-12T08:08:09	[sfnt] Better PS name handling (#54629). * 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.
65681e6d	2018-09-12T07:40:49	[truetype] Improve VF check. Triggered by https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=10255 * src/truetype/ttgxvar.c (ft_var_load_gvar): Use better limit check for `tupleCount'.

(FT_Outline_New, FT_Outline_Done): ... these functions. * docs/README: Updated.
809d5125	2018-08-31T22:49:19	* src/base/ftobjs.c (ft_glyphslot_preset_bitmap): Check glyph format.

Triggered by https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=10054 * src/truetype/ttgload.c (load_truetype_glyph): Don't use variable `opened_frame' to trace whether a frame must be closed at the end of function: This fails because `TT_Vary_Apply_Glyph_Deltas' (which gets called for space glyphs) uses a frame by itself. Instead, close the frame after loading the header, then use another frame for the remaining part of the glyph later on. Also avoid calling `tt_get_metrics' twice under some circumstances.

195728d5	2018-08-25T12:17:30	* src/tools/docmaker: Remove `docmaker'. `Docmaker' has now upgraded to `docwriter', a pip package available at https://pypi.org/project/docwriter/

(TT_Load_Simple_Glyph): Use new macros to make code more readable. Remove useless adjustment of `outline->tags' elements.

Fix handing 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. 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.

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 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.
