Werner Lemberg 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.
Werner Lemberg 6f918969 2015-07-04T11:35:28 Minor documentation issue.
Werner Lemberg 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.
Werner Lemberg 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.
Werner Lemberg 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.
Werner Lemberg 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.
Werner Lemberg a678560d 2015-05-28T17:31:15 Minor.
Werner Lemberg 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.
Werner Lemberg 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.
Werner Lemberg 0aa36160 2015-03-08T22:50:37 Formatting, whitespace, addition of some comments.
Werner Lemberg 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.
Werner Lemberg 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>.
Werner Lemberg 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.
Werner Lemberg f57fc59e 2015-01-17T20:41:43 Run `src/tools/update-copyright'.
Werner Lemberg 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.
Werner Lemberg 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.
Werner Lemberg 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.
Werner Lemberg e3c93015 2013-03-14T11:21:17 */*: Use FT_Err_Ok only. This is a purely mechanical conversion.
Werner Lemberg 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.
Werner Lemberg 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.

Werner Lemberg 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.

suzuki toshiya ec7bc863 2009-08-01T00:32:19 truetype: Extend TrueType GX packed deltas to FT_Offset.
Werner Lemberg 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.
Werner Lemberg b3e6df69 2009-03-21T10:45:18 Really fix Ghostscript Coverity issue #3904.
Werner Lemberg 4d1a34ce 2009-03-21T10:42:56 Another redundant header inclusion. * src/truetype/ttgxvar.c: Fix Ghostscript Coverity issue #4041.
