Werner Lemberg 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.
Alexei Podtelezhnikov 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.
Alexei Podtelezhnikov 4500c701 2018-09-26T22:04:50 Typo.
Werner Lemberg 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.
Alexei Podtelezhnikov 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.
Alexei Podtelezhnikov 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.
Alexei Podtelezhnikov f26d5775 2018-09-21T20:34:58 * src/base/ftobjs.c (ft_glyphslot_reset_bimap): Further tweak.
Ben Wagner 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.
Werner Lemberg 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.
Werner Lemberg 493aa68f 2018-09-21T08:32:22 [base] Some comments.
Alexei Podtelezhnikov 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.
Alexei Podtelezhnikov 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.
Werner Lemberg 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.
Alexei Podtelezhnikov 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.
Alexei Podtelezhnikov 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.

John Tytgat 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.

Werner Lemberg 6e339b8d 2018-08-26T11:59:02 [truetype] Avoid nested frames. 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.

Alexei Podtelezhnikov 4b97ab98 2018-07-24T23:01:34 [build] Fortify dllexport/dllimport attributes (#53969,#54330). 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/.
Werner Lemberg d8ea52de 2018-07-24T23:03:06 [type1] Check relationship between number of axes and designs. For Multiple Masters fonts We don't support intermediate designs; this implies that number_of_designs == 2 ^^ number_of_axes Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=9557 * src/type1/t1load.c (T1_Open_Face): Ensure above constraint.
