* Add function `FT_Get_GlyphLayers' to access `COLR' table data.Werner Lemberg2018-05-164-18/+43
| | | | | | | | | | | * include/freetype/internal/ftobjs.h (FT_Glyph_LayerRec): Move this structure to... * include/freetype/freetype.h (FT_Glyph_LayerRec): ... this header file. (FT_Glyph_Layer): New typedef. Update code to use it where appropriate. * src/base/ftobjs.c (FT_Get_GlyphLayers): New function.
* [base] Fix mono bitmap presetting (#53896).Alexei Podtelezhnikov2018-05-151-19/+13
| | | | | | | | | | | | It is rather fundamental to set monochrome bitmap based on rounded CBox because the b/w rasterizer turns on pixels when their centers are inside the glyph outline. The dropout control is unpredictable and can distort narrow glyphs if the bitmap is too wide. Reported by Chris Liddell. * src/base/ftobjs.c (ft_glyphslot_preset_bitmap): If BBox boundaries are too close, adjust them before rounding.
* [psaux] Fix compiler warning (#53915).Werner Lemberg2018-05-151-2/+9
| | | | * src/psaux/psft.c (cf2_freeT1SeacComponent): Do it.
* [sfnt] Fix memory leak in handling `COLR' data.Werner Lemberg2018-05-152-9/+8
| | | | | | * src/truetype/ttgload.c (TT_Load_Glyph): Free old `layers' array before reassigning allocated memory. Only allocate `color_layers' if we don't have one already.
* Grammar fixes.Werner Lemberg2018-05-151-4/+4

* [sfnt] If `COLR' is present, don't assume that all glyphs use it.Werner Lemberg2018-05-153-8/+16
| | | | | | | | * src/sfnt/ttcolr.c (tt_face_load_colr_layers): Return FT_Err_Ok if current glyph is not a `COLR' base glyph. * src/truetype/ttgload.c (TT_Load_Glyph): Don't allocate `color_layers' if there are no color layers.

| | | | * src/base/ftsnames.c [!TT_CONFIG_OPTION_SFNT_NAMES]: Implement it.

* [sfnt] Preliminary support of coloured layer outlines.Shao Yu Zhang2018-05-1310-4/+737
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit enables OpenType's COLR/CPAL table handling; a typical application are color emojis that can be scaled to any size. If the color palette does not exist or is invalid, the rendering step rasterizes the outline instead. The current implementation assumes that the foreground is black. Enable this by defining option TT_CONFIG_OPTION_COLOR_LAYERS. There are still some issues with metrics; additionally, an API to fetch color layers is missing. * devel/ftoption.h, include/freetype/config/ftoption.h (TT_CONFIG_OPTION_COLOR_LAYERS): New macro. * include/freetype/internal/ftobjs.h (FT_Glyph_LayerRec, FT_Colr_InternalRec): New structures. (FT_Slot_InternalRec): Add `color_layers' field. * include/freetype/internal/sfnt.h (TT_Load_Colr_Layer_Func, TT_Blend_Colr_Func): New function types. (SFNT_Interface): Add `load_colr', `free_colr', `load_colr_layer', and `colr_blend' fields. * include/freetype/internal/tttypes.h (TT_FaceRec): Add `colr_and_cpal' field. * include/freetype/internal/tttags. (TTAG_COLR, TTAG_CPAL): New macros. * src/sfnt/ttcolr.c, src/sfnt/ttcolr.h: New files. * src/base/ftobjs.c (ft_glyphslot_done, FT_Render_Glyph_Internal): Handle glyph color layers. * src/sfnt/Jamfile (_sources), src/sfnt/rules.mk (SFNT_DRV_SRC): Add `ttcolr.c'. * src/sfnt/sfdriver.c: Include `ttcolr.h'. (PUT_COLOR_LAYERS): New macro. Update call to `FT_DEFINE_SFNT_INTERFACE'. * src/sfnt/sfnt.c: Include `ttcolr.c'. * src/sfnt/sfobjs.c (sfnt_load_face): Load `COLR' and `CPAL' tables. (sfnt_done_face): Updated. * src/truetype/ttgload.c (TT_Load_Glyph): Handle color layers.

* [autofit] Avoid potential SEGV if running out of memory.Werner Lemberg2018-05-083-22/+75
| | | | | | | | | | | | | | | | | Problem reported by Shailesh Mistry <shailesh.mistry@hotmail.co.uk>. * src/autofit/afshaper.c (af_shaper_buf_create, af_shaper_buf_destroy) [!FT_CONFIG_OPTION_USE_HARFBUZZ]: Don't allocate and free a four-byte buffer. Instead, make those functions no-ops; the calling functions will provide a pointer to a buffer instead. * src/autofit/afcjk.c (af_cjk_metrics_init_widths, af_cjk_metrics_init_blues, af_cjk_metrics_check_digits), src/autofit/aflatin.c (af_latin_metrics_init_widths, af_latin_metrics_init_blues, af_latin_metrics_check_digits) [!FT_CONFIG_OPTION_USE_HARFBUZZ]: Use pointer to local variable for `shaper_buf'.
