Werner Lemberg 72091103 2016-12-21T23:46:29 * src/truetype/ttgxvar.c (TT_Vary_Apply_Glyph_Deltas): Thinko. I should really stop coding late in the evening... Thanks again to Ben for checking.
Werner Lemberg d44daf9e 2016-12-21T23:03:48 * src/truetype/ttgxvar.c (TT_Vary_Apply_Glyph_Deltas): Thinko. Don't apply deltas twice for non-phantom points. Spotted by Ben Wagner.
Werner Lemberg 64a91137 2016-12-21T19:30:33 [truetype, sfnt] Introduce font variation flags to `TT_Face'. * include/freetype/internal/tttypes.h (TT_FACE_FLAG_VAR_XXX): New macros describing available functionality of various OpenType tables related to font variation. (TT_Face): New fields `variation_support' and `mvar_support', replacing and extending `use_fvar'. * src/sfnt/sfobjs.c (sfnt_init_face, sfnt_load_face): Use `variation_support'. * src/truetype/ttgxvar.c (ft_var_load_hvar): Set `variation_support' field. (TT_Vary_Apply_Glyph_Deltas): Updated.
Werner Lemberg a8652c59 2016-12-18T18:12:03 [truetype, cff] Extend `get_var_blend' function of MM service. In particular, we need access to named instance data. * include/freetype/internal/services/svmm.h (FT_Get_Var_Blend_Func): Add argument for `FT_MM_Var'. * src/cff/cffload.c (cff_get_var_blend): Updated. * src/cff/cffload.h: Updated. * src/cff/cf2ft.c (cf2_getNormalizedVector): Updated. * src/truetype/ttgxvar.c (tt_get_var_blend): Updated. Accept value `NULL' for arguments. * src/truetype/ttgxvar.h: Updated.
Werner Lemberg 25f3ac2b 2016-12-18T15:50:18 [sfnt] Handle `fvar' with zero axes as a non-MM font. This is better behaviour than exiting with an error. * include/freetype/internal/tttypes.h (TT_Face): Add `use_fvar' field. * src/sfnt/sfobjs.c (sfnt_init_face): Compute `use_fvar', also updating the validation code. Use `use_fvar' to compute FT_FACE_FLAG_MULTIPLE_MASTERS. * src/truetype/ttgxvar.c (TT_Get_MM_Var): Remove `fvar' validation code.
Werner Lemberg 5d664b6d 2016-12-17T20:47:42 Use FT_SET_ERROR where useful. Other minor code formatting.

Dave Arnold edf40148 2016-12-15T21:56:44 [cff] Implement CFF2 support (2/2). The font variation code. All parts dependent on the GX code in the `truetype' module are guarded with TT_CONFIG_OPTION_GX_VAR_SUPPORT. In other words, you can still compile the `cff' module without defining TT_CONFIG_OPTION_GX_VAR_SUPPORT (which brings you CFF2 support without font variation). * src/cff/cf2font.c (cf2_font_setup): Add support for font variation. * src/cff/cf2font.h (CF2_Font): Add fields for variation data. * src/cff/cf2ft.c (cf2_free_instance): Free blend data.

(cf2_interpT2CharString): Handle `vsindex' and `blend' opcodes. * src/cff/cffload.c (FT_fdot14ToFixed): New macro. (cff_vstore_done, cff_vstore_load): New functions. (cff_blend_clear, cff_blend_doBlend, cff_blend_build_vector, cff_blend_check_vector): New functions. (cff_load_private_dict): Add arguments for blend vector. Handle blend data. (cff_subfont_load, cff_subfont_done): Updated. (cff_font_load): Handle CFF2 variation store data. (cff_font_done): Updated. * src/cff/cffload.h: Include `cffparse.h'. Updated. * src/cff/cffobjs.c (cff_face_done): Updated. * src/cff/cffparse.c: Include `cffload.h'. (cff_parse_num): Handle internal value 255. (cff_parse_vsindex, cff_parse_blend): New functions. (CFF_FIELD_BLEND): New macro. (cff_parser_run): Updated. * src/cff/cffparse.h (cff_kind_blend): New enum value. * src/cff/cfftoken.h: Handle `vstore', `vsindex', and `blend' dictionary values. * src/cff/cfftypes.h (CFF_VarData, CFF_AxisCoords, CFF_VarRegion, CFF_VStore, CFF_Blend): New structures. (CFF_FontRecDict): Add `vstore_offset' field. (CFF_Private): Add `vsindex' field. (CFF_SubFont): Add fields for blend data. (CFF_Font): Add `vstore' field. * src/truetype/ttgxvar.c (TT_Get_MM_Var): `CFF2' is equal to `gvar', since glyph variation data is directly embedded. (TT_Set_MM_Blend): Don't load `gvar' table for CFF2 fonts.
Werner Lemberg 3bd79cc2 2016-12-15T14:34:57 [truetype] Provide HVAR advance width variation as a service. Everything is guarded with TT_CONFIG_OPTION_GX_VAR_SUPPORT. * src/truetype/ttdriver.c (tt_service_metrics_variations): Updated. * src/truetype/ttgxvar.c (TT_Vary_Apply_Glyph_Deltas): Prevent double adjustment of advance width. * src/sfnt/ttmtx.c: Include FT_SERVICE_METRICS_VARIATIONS_H. (tt_face_get_metrics): Apply metrics variations.
Dave Arnold aa0c4b4f 2016-12-15T14:04:51 [truetype] Provide function to apply `HVAR' advance width variation. * src/truetype/ttgxvar.c (tt_hadvance_adjust): New function. * src/truetype/ttgxvar.h: Updated.
Dave Arnold 097cd874 2016-12-15T12:58:26 [truetype] Add `HVAR' table parsing. Note that this is not complete yet; it only handles advance width variation. Activation of the code follows in another commit. * include/freetype/ftmm.h (FT_Var_Named_Style): Add `psid' member. * src/truetype/ttgxvar.h (GX_HVarData, GX_AxisCoords, GX_HVarRegion, GX_HVStore, GX_WidthMap): New auxiliary structures for...

Behdad Esfahbod b72858c9 2016-11-03T06:41:00 [truetype] Clamp variation requests to valid range. This is required by OpenType 1.8; it also avoids rounding surprises. * src/truetype/ttgxvar.c (TT_Set_Var_Design): Clamp design coordinates outside of the allowed range to always stay within the range instead of producing an error.

(TT_Load_Glyph): Load embedded bitmaps for default instance only. * src/truetype/ttgxvar.c (TT_Set_MM_Blend): Compute `is_default_instance'.
Werner Lemberg 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.
Werner Lemberg 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.

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'.
Werner Lemberg 631e2181 2016-07-14T06:25:05 * src/truetype/ttgxvar.c (TT_Vary_Apply_Glyph_Deltas): Fix tracing.
Behdad Esfahbod 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.

Behdad Esfahbod 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.
Werner Lemberg 32950391 2016-02-15T12:54:40 Whitespace.

Werner Lemberg 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.
Werner Lemberg 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.
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 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 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.

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.

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.
