4e659d7e	2016-09-03T18:14:00	[truetype] More fixes for handling of GX deltas. Problems reported by Bob Taylor <Bob.Taylor@monotype.com>. * src/truetype/ttgxvar.c (TT_Vary_Apply_Glyph_Deltas): Fix rough sanity test for glyph variation array header size. Always set stream position before reading packed x and y deltas. Fix thinko w.r.t. `localpoints' array.
7f63105c	2016-07-19T21:35:58	[truetype] Sanitizer fix, second try. * src/truetype/ttgxvar.c (ft_var_readpackedpoints): Fix boundary tests and use only one slot more.
9f6426eb	2016-07-19T07:23:17	Thinko; fix previous commit.
e69f34b1	2016-07-19T07:06:19	[truetype] Sanitizer fix. * src/truetype/ttgxvar.c (ft_var_readpackedpoints): Increase array to fix nested loops.
69446ddc	2016-07-16T10:52:38	[truetype] Make all glyphs in `Zycon' GX font work. * src/truetype/ttgxvar.c (ft_var_readpackedpoints): Fix boundary tests.
a3b61253	2016-07-16T08:16:16	[truetype] Fix GX delta tracing. * src/truetype/ttgxvar.c (TT_Vary_Apply_Glyph_Deltas): Trace relative point movements.
f147fb28	2016-07-16T07:06:21	[truetype] More fixes for GX. This finally fixes the rendering of the cyclist and the lizard in the `Zycon' font. * src/truetype/ttgxvar.c (ft_var_readpackedpoints): `first' point index is always cumulative. (tt_handle_deltas): Rename to... (tt_interpolate_deltas): ... This. Add new parameter for output point array. Update caller. (TT_Vary_Apply_Glyph_Deltas): Add `points_out' array; it now holds the intermediate results of `tt_interpolate_deltas' that are to be added to `outline->points'.
631e2181	2016-07-14T06:25:05	* src/truetype/ttgxvar.c (TT_Vary_Apply_Glyph_Deltas): Fix tracing.
0f9ddf20	2016-07-14T06:08:39	[truetype] Fix gxvar delta interpolation. The coordinates of the base font should be used for interpolation purposes, NOT the current points (i.e., the result of accumulation of previous deltas). * src/truetype/ttgxvar.c (TT_Vary_Apply_Glyph_Deltas): Initialize `points_org' before looping over all tuples.
99eff678	2016-04-16T07:32:23	[truetype] Another fix for non-intermediate GX tuples. * src/truetype/ttgxvar.c (ft_var_apply_tuple): Add some missing cases.
74c0a72d	2016-03-09T20:35:27	[truetype] Fix handling of non-intermediate GX tuples. We probably did not notice this as all fonts we tested had only tuple_coords[i] be +1 or -1 for non-intermediate tuples. * src/truetype/ttgxvar.c (ft_var_apply_tuple): Implement it.
32950391	2016-02-15T12:54:40	Whitespace.
9adeab64	2016-01-13T11:54:10	Update copyright year.
43a96eb2	2015-10-13T11:18:55	[truetype] Refine some GX sanity tests. Use the `gvar' table size instead of the remaining bytes in the stream. * src/truetype/ttgxvar.h (GX_BlendRec): New field `gvar_size'. * src/truetype/ttgxvar.c (ft_var_load_gvar): Set `gvar_size'. (ft_var_readpackedpoints, ft_var_readpackeddeltas: New argument `size'. (tt_face_vary_cvt, TT_Vary_Apply_Glyph_Deltas): Updated.
052f6c56	2015-10-13T08:24:32	[truetype] Another GX sanity test. * src/truetype/ttgxvar.c (TT_Vary_Apply_Glyph_Deltas): Check `tupleCount'. Add tracing message.
7ef0d866	2015-10-13T08:14:20	[truetype] Fix memory leak for broken GX fonts (#46188). * src/truetype/ttgxvar.c (TT_Vary_Apply_Glyph_Deltas): Fix scope of deallocation.
f96094ee	2015-10-13T07:13:56	[truetype] Fix commit from 2015-10-10. * src/truetype/ttgxvar.c (ft_var_load_gvar): Add missing error handling body to condition.
da34673e	2015-10-10T10:21:27	[truetype] More sanity tests for GX handling. These tests should mainly help avoid unnecessarily large memory allocations in case of malformed fonts. * src/truetype/ttgxvar.c (ft_var_readpackedpoints, ft_var_readpackeddeltas): Check number of points against stream size. (ft_var_load_avar): Check `pairCount' against table length. (ft_var_load_gvar): Check `globalCoordCount' and `glyphCount' against table length. (tt_face_vary_cvt): Check `tupleCount' and `offsetToData'. Fix trace. (TT_Vary_Apply_Glyph_Deltas): Fix trace. Free `sharedpoints' to avoid memory leak.
c220d8b4	2015-10-10T08:13:04	[truetype] Better protection against malformed GX data (#46166). * src/truetype/ttgxvar.c (TT_Vary_Apply_Glyph_Deltas): Correctly handle empty `localpoints' array.
70e9d815	2015-08-02T09:42:12	Fix more invalid left-shifts. * src/pfr/pfrgload.c (pfr_glyph_load_compound): Use multiplication, not left-shift. * src/truetype/ttgxvar.c (ft_var_load_avar, ft_var_load_gvar, tt_face_vary_cvt, TT_Vary_Apply_Glyph_Deltas): Use multiplication, not left-shift.
6f918969	2015-07-04T11:35:28	Minor documentation issue.
eb1bba9b	2015-06-30T09:46:39	Fix some clang compiler warnings. * src/base/ftoutln.c (FT_Outline_EmboldenXY), src/cff/cf2intrp.c (cf2_interpT2CharString), src/truetype/ttgload.c (load_truetype_glyph), src/truetype/ttgxvar.c (tt_handle_deltas), src/truetype/ttinterp.c (Ins_INSTCTRL): Fix signedness issues.
e9df4e47	2015-05-31T12:21:34	[truetype] In GX, make private point numbers work correctly. This is completely missing in Apple's documentation: If a `gvar' tuple uses private point numbers (this is, deltas are specified for some points only), the uncovered points must be interpolated for this tuple similar to the IUP bytecode instruction. Examples that need this functionality are glyphs `Oslash' and `Q' in Skia.ttf. * src/truetype/ttgxvar.c (tt_delta_shift, tt_delta_interpolate, tt_handle_deltas): New functions. (TT_Vary_Get_Glyph_Deltas): Renamed to... (TT_Vary_Apply_Glyph_Deltas): ... this; it directly processes the points and does no longer return an array of deltas. Add tracing information. Call `tt_handle_deltas' to interpolate missing deltas. Also fix a minor memory leak in case of error. * src/truetype/ttgxvar.h: Updated. * src/truetype/ttgload.c (TT_Process_Simple_Glyph, load_truetype_glyph): Updated.
9845c1d4	2015-05-31T11:57:31	[truetype] In GX, make intermediate tuplets work at extrema. * src/truetype/ttgxvar.c (ft_var_apply_tuple): Fix range condition.
cdee7d14	2015-05-31T11:54:42	[truetype] Add tracing information to GX code. * src/truetype/ttgxvar.c (ft_var_load_avar, ft_var_load_gvar, ft_var_apply_tuple, TT_Get_MM_Var, TT_Set_MM_Blend, TT_Set_Var_Design, tt_face_vary_cvt): Do it.
a678560d	2015-05-28T17:31:15	Minor.
10e2bb8b	2015-03-29T13:32:47	[type1, truetype] Make the MM API more flexible w.r.t. `num_coords'. This commit allows `num_coords' to be larger or smaller than the number of available axes while selecting a design instance, either ignoring excess data or using defaults if data is missing. * src/truetype/ttgxvar.c (TT_Set_MM_Blend, TT_Set_Var_Design): Implement it. * src/type1/t1load.c (T1_Set_MM_Blend, T1_Set_MM_Design, T1_Set_Var_Design): Ditto.
6cc425db	2015-03-21T06:51:07	[truetype] Improve `gvar' handling. * src/truetype/ttgxvar.c (ft_var_readpackedpoints): Correctly handle single-element runs. Cf. glyph `Q' in Skia.ttf with weights larger than the default.
0aa36160	2015-03-08T22:50:37	Formatting, whitespace, addition of some comments.
328b7923	2015-03-04T08:40:23	[truetype] Some fixes and code refactoring in `ttgxvar.c'. * src/truetype/ttgxvar.c (ft_var_readpackedpoints): Fix return value of `point_cnt' if two bytes are read. Use a more vertical coding style. (ft_var_readpackeddeltas): Use FT_UInt for `delta_cnt' parameter. Use a more vertical coding style.
3a1df3e1	2015-02-19T15:42:48	* src/truetype/ttgxvar.c (TT_Get_MM_Var): Ignore `countSizePairs'. This is hard-coded to value 2 in `fvar' version 1.0 (and no newer version exists), but some fonts set it incorrectly. Problem reported by Adam Twardoch <adam@fontlab.com>.
1f7a4e1f	2015-02-17T10:17:56	[truetype] Finish compiler warning fixes for signedness issues. * src/truetype/ttgxvar.c, src/truetype/ttsubpix.c, src/truetype/ttsubpix.h: Apply.
f57fc59e	2015-01-17T20:41:43	Run `src/tools/update-copyright'.
6689a009	2014-11-25T08:53:09	[Savannah bug #43682] Properly handle missing return errors. The functions in this patch do return non-trivial errors that must be taken care of. * src/autofit/afloader.c (af_loader_load_g), src/base/ftobjs.c (FT_Render_Glyph_Internal), src/base/ftoutln.c (FT_Outline_Render), src/cff/cffgload.c (cff_decoder_parse_charstrings) <cff_op_endchar>, src/psaux/psobjs.c (ps_parser_load_field_table), src/psaux/t1decode (t1_decoder_parse_charstrings) <op_endchar>, src/truetype/ttgload.c (load_truetype_glyph <subglyph loop>, tt_loader_init, TT_Load_Glyph), src/truetype/ttgxvar.c (TT_Set_MM_Blend), src/truetype/ttobjs.c (tt_size_run_fpgm, tt_size_run_prep): Do it.
badf3178	2013-06-06T09:16:38	Next round of compiler fixes. * builds/win32/ftdebug.c, builds/wince/ftdebug.c (ft_debug_init): Add proper cast. * include/freetype/internal/ftserv.h (FT_SERVICE_UNAVAILABLE): Fix cast. * include/freetype/internal/ftstream.h: Decorate stream and frame macros with `FT_Long' and `FT_ULong' as appropriate. * src/base/ftrfork.c (raccess_guess_darwin_hfsplus, raccess_guess_darwin_newvfs): Use cast. * src/bdf/bdflib.c (_bdf_set_default_spacing): Use cast. * src/cache/ftcmanag.c (FTC_Manager_Check): Fix cast. * src/cache/ftcmanag.h (FTC_ManagerRec): Ditto. * src/cff/cf2arrst.c (cf2_arrstack_setNum_Elements): Use cast. * src/cff/cf2ft.c (cf2_freeSeacComponent): Ditto. * src/cff/cffobjs.c (remove_subset_prefix, remove_style): Ditto. * src/cid/cidparse.c (cid_parser_new): Use cast. * src/pcf/pcfdrivr.c (PCF_Glyph_Load): Use cast. * src/psaux/psobjs.c (reallocate_t1_table): Fix argument type. * src/raster/ftraster.c (ft_black_reset): Use cast. * src/truetype/ttgxvar.c (FT_Stream_FTell): Use cast. (ALL_POINTS): Fix cast. * src/type1/t1driver.c (t1_ps_get_font_value): Add casts. * src/type1/t1parse.c (T1_Get_Private_Dict): Add cast.
45392b77	2013-06-05T13:43:20	Fix compiler warnings. * include/freetype/internal/ftmemory.h: Decorate memory allocation macros with `FT_Long' where appropriate. Remove duplicate of FT_MEM_QRENEW_ARRAY definition. * src/base/ftbitmap.c (ft_gray_for_premultiplied_srgb_bgra): Use cast. * src/base/ftobjs.c: Add warning disabling pragma for MSVC while including `md5.c'. * src/cff/cf2intrp.c (cf2_interpT2CharString) <cf2_cmdESC>: Add cast. * src/sfnt/ttsbit.c (tt_sbit_decoder_load_compound): Fix casts. (tt_sbit_decoder_load_bitmap): Beautification. * src/smooth/ftsmooth.c (ft_smooth_render_generic): Initialize variables (earlier). * src/truetype/ttgload.c (TT_Process_Simple_Glyph): Pacify compiler. * src/truetype/ttgxvar.c (TT_Get_MM_Var): Use unsigned constants where appropriate. * src/type1/t1load.c (T1_Get_MM_Var): Ditto.
e3c93015	2013-03-14T11:21:17	/: Use FT_Err_Ok only. This is a purely mechanical conversion.
059bc335	2013-03-14T10:27:35	/: Use `FT_THROW'. This is essentially a mechanical conversion, adding inclusion of `FT_INTERNAL_DEBUG_H' where necessary, and providing the macros for stand-alone compiling modes of the rasterizer modules. To convert the remaining occurrences of FT_Err_XXX and friends it is necessary to rewrite the code. Note, however, that it doesn't harm if some cases are not handled since FT_THROW is a no-op.
a9f6f85e	2012-12-17T09:08:09	Various compiler warning fixes. * include/freetype/internal/ftserv.h (FT_SERVICE_UNAVAILABLE): Use `logical not' operator instead of negation. The idea is that `~' returns exactly the data type enforced by the cast to a pointer (be it 32bit or 64bit or whatever), while a negative integer has not this flexibility. * src/cache/ftccmap.c (FTC_CMAP_UNKNOWN): Ditto. * src/truetype/ttgxvar.c (ALL_POINTS, TT_Get_MM_Var): Ditto. * src/type/t1load.c (T1_Get_MM_Var): Ditto. (parse_blend_axis_types): Use cast. * src/bdf/bdflib.c (_bdf_readstream): Use cast.
4ae9cbb0	2012-12-01T23:36:02	[truetype, type1] Revise the use of FT_MulDiv. * src/truetype/ttgxvar.c: Updated. * src/truetype/ttobjs.c: Updated. * src/type1/t1load.c: Updated.
9c98fbf6	2011-10-01T09:25:55	Handle some border cases. * include/freetype/config/ftstdlib.h (FT_USHORT_MAX): New macro. * src/base/ftbitmap.c (FT_Bitmap_Convert): Protect against invalid value of `target->rows'. * src/psaux/t1decode.c (t1_decoder_parse_charstrings): Add check for flex start. * src/raster/ftrend1.c (ft_raster1_render): Check `width' and `height'. * src/truetype/ttgxvar.c (TT_Vary_Get_Glyph_Deltas): Protect against invalid values in `localpoints' array.

(TT_Get_MM_Var): Init `mmvar'. * src/type1/t1load.c (T1_Get_MM_Var): Ditto. * src/cff/cffdrivr.c (cff_ps_get_font_info): Init `font_info'. * src/cff/cffload.c (cff_index_get_pointers): Init `t'. (cff_font_load): Init `sub'. * src/cff/cffobjs.c (cff_size_init): Init `internal'. (cff_face_init): Init `cff'. * src/pfr/pfrload.c (pfr_extra_item_load_stem_snaps): Init `snaps'. * src/pcf/pcfread.c (pcf_get_properties): Init `properties'. (pcf_get_bitmaps): Init `offsets'. (pcf_get_encodings): Init `tmpEncoding'. * src/sfnt/ttload.c (tt_face_load_gasp): Init `gaspranges'. * src/sfnt/ttsbit.c (Load_SBit_Image): Init `components'. * src/cache/ftcmru.c (FTC_MruList_New): Init `node'. * src/gzip/ftgzip.c (FT_Stream_OpenGzip): Init `zip' and `zip_buff'. * src/lzw/ftlzw.c (FT_Stream_OpenLZW): Init `zip'. * src/bzip2/ftbzip2.c (FT_Stream_OpenBzip2): Init `zip'.
59eb9f8c	2010-10-12T07:49:17	Fix Savannah bug #31310. * src/truetype/ttgxvar.c (ft_var_readpackedpoints): Protect against invalid `runcnt' values.
c8f5b98b	2010-07-12T21:13:22	Remove C++ warnings. /: Initialize pointers where necessary to make g++ happy.
25e742c5	2010-04-06T16:42:56	Add overflow check to `fvar' table. * src/truetype/ttgxvar.c (TT_Get_MM_Var): Check axis and instance count.
7da7ad94	2009-12-16T18:13:55	Really fix compiler warnings. Reported by Sean. * src/truetype/ttgxvar.c (GX_PT_POINTS_ARE_WORDS, GX_PT_POINT_RUN_COUNT_MASK): Convert enum values to macros.

ec7bc863	2009-08-01T00:32:19	truetype: Extend TrueType GX packed deltas to FT_Offset.
858abbed	2009-06-26T06:15:41	For warning messages, replace FT_ERROR with FT_TRACE0. FT_ERROR is now used only if a function produces a non-zero `error' value. Formatting, improving and harmonizing debug strings.
b3e6df69	2009-03-21T10:45:18	Really fix Ghostscript Coverity issue #3904.
4d1a34ce	2009-03-21T10:42:56	Another redundant header inclusion. * src/truetype/ttgxvar.c: Fix Ghostscript Coverity issue #4041.

(tt_cmap0_validate, tt_cmap2_validate, tt_cmap6_validate, tt_cmap8_validate, tt_cmap10_validate, tt_cmap12_validate): Use `FT_Error' as return type. (tt_cmap4_validate): Use `FT_Error' as return type. Return error code for unsorted cmap. (tt_cmap4_char_index, tt_cmap4_char_next): Use old code for unsorted cmaps. (tt_face_build_cmaps): Set `unsorted' variable in cmap. Minor formatting.
750fa961	2005-05-01T10:11:32	* Jamfile: removing otvalid from the list of compiled modules * include/freetype/internal/ftserv.h: added compiler pragmas to get rid of annoying warnings with Visual C++ compiler in maximum warning mode * src/autofit/afhints.c, src/autofit/aflatin.c, src/base/ftstroke.c, src/bdf/bdfdrivr.c, src/cache/ftcbasic.c, src/cache/ftccmap.c, src/cache/ftcmanag.c, src/cff/cffload.c, src/cid/cidload.c, src/lzw/zopen.c, src/otvalid/otvgdef.c, src/pcf/pcfread.c, src/sfnt/sfobjs.c, src/truetype/ttgxvar.c: removing compiler warnings
bbdee28f	2004-11-17T08:19:27	* builds/unix/configure.ac: Add `-fno-strict-aliasing' if gcc is used. * builds/unix/configure: Regenerated. * builds/unix/config.guess, builds/unix/config.sub: Updated from `config' CVS module at subversions.gnu.org. * src/cache/ftcglyph.c (FTC_GNode_UnselectFamily, FTC_GCache_Lookup): Fix comparison with zero. * docs/INSTALL.VMS: Updated. * vms_make.com: Updated.

2015-05-31T12:21:34

[truetype] In GX, make private point numbers work correctly. This is completely missing in Apple's documentation: If a `gvar' tuple uses private point numbers (this is, deltas are specified for some points only), the uncovered points must be interpolated for this tuple similar to the IUP bytecode instruction. Examples that need this functionality are glyphs `Oslash' and `Q' in Skia.ttf. * src/truetype/ttgxvar.c (tt_delta_shift, tt_delta_interpolate, tt_handle_deltas): New functions. (TT_Vary_Get_Glyph_Deltas): Renamed to... (TT_Vary_Apply_Glyph_Deltas): ... this; it directly processes the points and does no longer return an array of deltas. Add tracing information. Call `tt_handle_deltas' to interpolate missing deltas. Also fix a minor memory leak in case of error. * src/truetype/ttgxvar.h: Updated. * src/truetype/ttgload.c (TT_Process_Simple_Glyph, load_truetype_glyph): Updated.

*/*: Use `FT_THROW'. This is essentially a mechanical conversion, adding inclusion of `FT_INTERNAL_DEBUG_H' where necessary, and providing the macros for stand-alone compiling modes of the rasterizer modules. To convert the remaining occurrences of FT_Err_XXX and friends it is necessary to rewrite the code. Note, however, that it doesn't harm if some cases are not handled since FT_THROW is a no-op.
