Chris Liddell b75abeb5 2019-01-08T20:51:39 [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. * src/psauc/psinterp.c (cf2_interpT2CharString) <cf2_cmdCLOSEPATH>: Switch to calling `cf2_glyphpath_closeOpenPath'.
Werner Lemberg b89166cc 2018-12-29T08:55:01 * src/autofit/aflatin2.c: Some fixes from `aflatin.c' (#55310).
Werner Lemberg afa043de 2018-12-25T22:44:05 Fix links (mostly http -> https).
Werner Lemberg 5e029659 2018-12-25T19:24:06 * src/psaux/cffdecode.c (cff_operaor_seac): Fix numeric overflow. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=11915
Werner Lemberg ec439711 2018-12-12T19:59:42 [gxvalid] Fix compiler warnings. * src/gxvalid/gxvjust.c (gxv_just_check_max_gid), src/gxvalid/gxvmort.c (gxv_mort_coverage_validate): Use `FT_UNUSED'.
Werner Lemberg 3e8a2283 2018-12-11T23:54:17 * src/truetype/ttgload.c (TT_Hint_Glyph): Remove useless test. `control_len' only gets its value from `n_ins' (and vice versa), which is always read as `unsigned short' and thus can't be larger than 0xFFFF.
Werner Lemberg f1b6183f 2018-12-04T11:51:15 [bdf] Ignore data after `ENDFONT'. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=10798 * src/bdf/bdflib.c (_bdf_parse_end): New function. (_bdf_parse_glyphs): Switch to `_bdf_parse_end' after `ENDFONT' has been encountered.

(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.

Werner Lemberg efe7f648 2018-09-25T09:16:45 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.
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.
Werner Lemberg 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.
Werner Lemberg 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.
Werner Lemberg 7665914c 2018-09-13T08:58:49 * src/sfnt/sfdriver.c (sfnt_get_var_ps_name): Fix last commit.
Werner Lemberg a5818ed1 2018-09-13T08:46:44 * src/sfnt/sfdriver.c (sfnt_get_var_ps_name): Check `result'. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=10316
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 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'.
Werner Lemberg 53c5e4bd 2018-09-12T07:27:30 * src/truetype/ttgxvar.c (ft_var_load_gvar): Check `glyphoffsets'.
Armin Hasitzka 7b855ed9 2018-09-10T23:41:04 * src/pshinter/pshrec.c (t2_hints_stems): Mask numeric overflow. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=10215

Werner Lemberg 20957721 2018-08-26T15:15:56 ChangeLog*: s/\t/ /.
Nikhil Ramakrishnan f87b7117 2018-08-26T17:46:25 * configure: Copy assets required by docwriter. Copy directory `docs/reference/markdown' when FreeType is compiled in a different directory. Fixes `make refdoc' if builddir != srcdir. Reported as http://lists.nongnu.org/archive/html/freetype-devel/2018-08/msg00083.html
Werner Lemberg 13034e54 2018-08-26T12:22:51 * src/pshint/pshalgo.c (psh_hint_overlap): Fix numeric overflow. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=10057
Werner Lemberg 4738dcc4 2018-08-26T12:03:33 Minor tracing adjustments. * src/base/ftstream.c (FT_Stream_EnterFrame, FT_Stream_ExitFrame): Trace. * src/truetype/ttgload.c (TT_Access_Glyph_Frame): Remove tracing.
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.
Werner Lemberg b287c80b 2018-08-26T06:39:43 Various minor clean-ups. * src/base/ftapi.c: Remove. Unused. * src/base/Jamfile (_sources): Updated. * src/base/ftstream.c (FT_Stream_ReleaseFrame): Remove redundant code.

Werner Lemberg 45524679 2018-08-22T10:31:05 [truetype] Improve legibility of `glyf' parsing. * src/truetype/ttgload.c (ON_CURVE_POINT, X_SHORT_VECTOR, Y_SHORT_VECTOR, REPEAT_FLAG, X_POSITIVE, SAME_X, Y_POSITIVE, SAME_Y, OVERLAP_SIMPLE): New macros. (TT_Load_Simple_Glyph): Use new macros to make code more readable. Remove useless adjustment of `outline->tags' elements.
