6f09011f	2015-10-24T10:10:22	[sfnt] Sanitize bitmap strike glyph height. Problem reported by Nikolay Sivov <bunglehead@gmail.com>. * src/sfnt/ttsbit.c (tt_face_load_strike_metrics): Avoid zero value for `metrics->height' by applying some heuristics.

5339c75e	2015-09-24T13:39:44	[sfnt] Better checks for invalid cmaps (2/2) (#46019). While the current code in `FT_Get_Next_Char' correctly rejects out-of-bounds glyph indices, it can be extremely slow for malformed cmaps that use 32bit values. This commit tries to improve that. * src/sfnt/ttcmap.c (tt_cmap8_char_next, tt_cmap12_next, tt_cmap12_char_map_binary, tt_cmap13_next, tt_cmap13_char_map_binary): Reject glyph indices larger than or equal to the number of glyphs.

730b6d74	2015-09-19T12:41:12	[sfnt] Improve handling of invalid SFNT table entries (#45987). This patch fixes weaknesses in function `tt_face_load_font_dir'. - It incorrectly assumed that valid tables are always at the beginning. As a consequence, some valid tables after invalid entries (which are ignored) were never seen. - Duplicate table entries (this is, having the same tag) were not rejected. - The number of valid tables was sometimes too large, leading to access of invalid tables. * src/sfnt/ttload.c (check_table_dir): Add argument to return number of valid tables. Add another tracing message. (tt_face_load_font_dir): Only allocate table array for valid entries as returned by `check_table_dir'. Reject duplicate tables and adjust number of valid tables accordingly.
14d6b5d7	2015-08-13T15:22:17	[truetype] Introduce named instance access to GX fonts. For functions querying a face, bits 16-30 of the face index can hold the named instance index if we have a GX font. The indices start with value 1; value 0 indicates font access without GX variation data. * include/freetype/freetype.h (FT_FaceRec): Update documentation. * include/freetype/internal/sfnt.h: Ditto. * src/sfnt/sfobjs.c (sfnt_init_face) [TT_CONFIG_OPTION_GX_VAR_SUPPORT]: Get number of named instances and do argument checks.

(CCFLAGS): ... this. * src/Jamfile: Don't call `HDRMACRO' for `internal.h'; this is already handled in the top-level Jamfile. * src/autofit/Jamfile (DEFINES): Replace with... (CCFLAGS): ... this. (_sources): Add missing files. * src/cache/Jamfile: Don't call `HDRMACRO' for `ftcache.h'; it no longer contains macro header definitions. * src/base/Jamfile, src/cff/Jamfile, src/sfnt/Jamfile, src/truetype/Jamfile (_sources): Add missing files.

760d342d	2013-05-29T11:36:18	Add support for color embedded bitmaps (eg. color emoji). A new load flag, FT_LOAD_COLOR, makes FreeType load color embedded-bitmaps, following this draft specification https://color-emoji.googlecode.com/git/specification/v1.html which defines two new SFNT tables, `CBDT' and `CBLC' (named and modeled after `EBDT' and `EBLC', respectively). The color bitmaps are stored in the new FT_PIXEL_MODE_BGRA format to represent BGRA pre-multiplied sRGB images. If PNG support is available, PNG color images as defined in the same proposed specification are supported also. Note that color bitmaps are converted to grayscale if client didn't ask for color. * builds/unix/configure.raw: Search for libpng.

[sfnt] Improve handling of invalid SFNT table entries (#45987). This patch fixes weaknesses in function `tt_face_load_font_dir'. - It incorrectly assumed that valid tables are always at the beginning. As a consequence, some valid tables after invalid entries (which are ignored) were never seen. - Duplicate table entries (this is, having the same tag) were not rejected. - The number of valid tables was sometimes too large, leading to access of invalid tables. * src/sfnt/ttload.c (check_table_dir): Add argument to return number of valid tables. Add another tracing message. (tt_face_load_font_dir): Only allocate table array for valid entries as returned by `check_table_dir'. Reject duplicate tables and adjust number of valid tables accordingly.

[sfnt] `sbix' fix-ups. * src/sfnt/sfobjs.c (sfnt_load_face): Apple's `sbix' color bitmaps are rendered scaled and then the `glyf' outline rendered on top. We don't support that yet, so just ignore the `glyf' outline and advertise it as a bitmap-only font. * src/sfnt/ttsbit.c (tt_face_load_strike_metrics) [TT_SBIT_TABLE_TYPE_SBIX]: Return metrics in 26.6 units. (tt_face_load_sbix_image): Typo.

[sfnt] Ignore invalid magic number in `head' or `bhed'. Other font engines seem to ignore it also. Problem reported by Hin-Tak Leung <htl10@users.sourceforge.net>. * src/sfnt/ttload.c (check_table_dir): Don't abort but warn only if we have an invalid magic number.

Add support for color embedded bitmaps (eg. color emoji). A new load flag, FT_LOAD_COLOR, makes FreeType load color embedded-bitmaps, following this draft specification https://color-emoji.googlecode.com/git/specification/v1.html which defines two new SFNT tables, `CBDT' and `CBLC' (named and modeled after `EBDT' and `EBLC', respectively). The color bitmaps are stored in the new FT_PIXEL_MODE_BGRA format to represent BGRA pre-multiplied sRGB images. If PNG support is available, PNG color images as defined in the same proposed specification are supported also. Note that color bitmaps are converted to grayscale if client didn't ask for color. * builds/unix/configure.raw: Search for libpng. Add `--without-png' option. * devel/ftoption.h, include/freetype/config/ftoption.h (FT_CONFIG_OPTION_USE_PNG): New macro. * include/freetype/freetype.h (FT_LOAD_COLOR): New load flag. * include/freetype/ftimage.h (FT_Pixel_Mode): Add `FT_PIXEL_MODE_BGRA'. * include/freetype/tttags.h (TTAG_CBDT, TTAG_CBLC): New tags. * src/base/ftbitmap.c (FT_Bitmap_Embolden): Updated. (ft_gray_for_premultiplied_srgb_bgra): New function. (FT_Bitmap_Convert): Handle FT_PIXEL_MODE_BGRA. * src/sfnt/pngshim.c, src/sfnt/pngshim.h: New files. * src/sfnt/sfnt.c: Include `pngshim.c'. * src/sfnt/ttsbit.c: Include FT_BITMAP_H and `pngshim.h' (tt_face_load_eblc): Load `CBLC'. (tt_sbit_decoder_init): Load `CBDT'. (tt_sbit_decoder_alloc_bitmap): Pass load flags to select between color and grayscale bitmaps. Set `num_grays'. This is used by `ftview' to choose the blending algorithm. (tt_sbit_decoder_load_byte_aligned, tt_sbit_decoder_load_bit_aligned, tt_sbit_decoder_load_compound, tt_sbit_decoder_load_image): Pass load flag. s/write/pwrite/. Don't call `tt_sbit_decoder_alloc_bitmap'. Updated. (tt_sbit_decoder_load_png) [FT_CONFIG_OPTION_USE_PNG]: New function. (tt_sbit_decoder_load_bitmap): Pass load flag. Handle new glyph formats 17, 18, and 19. Call `tt_sbit_decoder_alloc_bitmap'. Flatten color bitmaps if necessary. (tt_face_load_sbit_image): Updated. * src/sfnt/rules.mk (SFNT_DRV_SRC): Add `pngshim.c'. * docs/CHANGES: Updated.
