Werner Lemberg 1949a7ec 2022-03-19T18:51:34 Add `FT_PARAM_TAG_IGNORE_SBIX`. This is another bit to handle 'sbix' tables as described in the OpenType specification. * include/freetype/ftparams.h (FT_PARAM_TAG_IGNORE_SBIX): New macro. * src/sfnt/sfobjc.c (is_apple_sbix): Rename to... (has_sbix): ... this. Check for more sbit tables. Handle `FT_PARAM_TAG_IGNORE_SBIX` to eventually control `has_sbix`. Only call sbit table loader if an sbit table is present.
Werner Lemberg ac4c1ebf 2022-02-07T06:55:54 [truetype] Fix 'sbix' table handling. * src/sfnt/ttsbit.c (tt_face_load_sbix_image): Correct calculation of 'metrics->horiBearingY'. Set vertical metrics. * src/sfnt/sfobjs.c (sfnt_load_face): Adjust setting of `FT_FACE_FLAG_SBIX`. Handle metrics of fonts with 'sbix' table. * src/truetype/ttgload.c (TT_Load_Glyph): For 'sbix' embedded bitmaps, apply bbox offset and bearing values of the corresponding glyph in the 'glyf' table if it exists and has a contour. * src/truetype/ttobjs.c (tt_face_init): Handle font with 'sbix' table. Fixes issue #998.
Werner Lemberg 907715a6 2022-02-09T07:31:56 Add `FT_FACE_FLAG_SBIX` and `FT_HAS_SBIX`. Fonts with 'sbix' tables need special handling by the application. * include/freetype/freetype.h (FT_FACE_FLAG_SBIX, FT_HAS_SBIX): New macros. * src/sfnt/sfobjs.c (sfnt_load_face): Set `FT_FACE_FLAG_SBIX` if 'sbix' table is present.
Werner Lemberg 53dfdcd8 2022-03-17T19:24:16 [sfnt] Avoid invalid face index. Fixes #1138. * src/sfnt/sfobjs.c (sfnt_init_face), src/sfnt/sfwoff2.c (woff2_open_font): Check `face_index` before decrementing.

Werner Lemberg d899b200 2021-11-08T12:27:04 * src/sfnt/sfobjs.c (sfnt_open_font): Fix typo.
Werner Lemberg 7ef26604 2021-11-04T09:10:57 [sfnt] Reduce footprint if WOFF and WOFF2 support is not needed. Based on a patch from metarutaiga (MR !106). The gist of this commit is that it doesn't make sense to support WOFF without compression (which would be only possible in WOFF 1.0 anyway). * src/sfnt/sfobjs.c (sfnt_open_font): Guard WOFF code with `FT_CONFIG_OPTION_USE_ZLIB` block. Guard WOFF2 code with `FT_CONFIG_OPTION_USE_BROTLI` block. * src/sfnt/sfwoff.c, src/sfnt/sfwoff.h: Guard files with `FT_CONFIG_OPTION_USE_ZLIB` blocks, not parts of the code. * src/sfnt/sfwoff2.c, src/sfnt/sfwoff2.h, src/sfnt/woff2tags.c, src/sfnt/woff2tags.h: Guard files with `FT_CONFIG_OPTION_USE_BROTLI` blocks, not parts of the code. Fixes #1111.
Alexei Podtelezhnikov 49270c17 2021-09-14T21:32:43 Replace boolean allocation macros with MEM ones. * src/base/ftbitmap.c (FT_Bitmap_Copy): Use MEM-macro. * src/base/ftobjs.c (ft_glyphslot_alloc_bitmap): Ditto. * src/bzip2/ftbzip2.c (ft_bzip2_alloc): Ditto. * src/cache/ftccache.c (ftc_cache_init): Ditto * src/gzip/ftgzip.c (ft_gzip_alloc): Ditto. * src/psnames/psmodule.c (ps_unicodes_init): Ditto. * src/sfnt/sfobjs.c (sfnt_load_face): Ditto. * src/sfnt/ttload.c (tt_face_load_name): Ditto.
Alexei Podtelezhnikov 058f3f2d 2021-09-13T16:24:25 [bdf, psnames, sfnt] Avoid some memory zeroing. * src/bdf/bdfdrivr.c (BDF_Face_Init): Use Q-macro. * src/sfnt/sfobjs.c (sfnt_load_face): Ditto. * src/psnames/psmodule.c (src/psnames/psmodule.c): Remove zero.
Alexei Podtelezhnikov 1bc801b0 2021-05-16T23:12:01 [sfnt] Additional guards on the POST table. Fixes timeout (#1055) analyzed by Ben Wagner, reported as https://crbug.com/1194092 * src/sfnt/ttload.c (tt_face_load_post): Check POST format. * src/sfnt/sfobjs.c (sfnt_load_face): Synthesize the missing unicode charmap only if the glyph names exist. * src/psnames/psmodule.c (ps_unicode_value): Short cut ".notdef" and ".null".

Werner Lemberg a6adb256 2020-12-02T14:15:07 * src/*: Don't use more than one '\n' in `FT_TRACE` and `FT_ERROR`. This ensures good logging output, with all lines having a proper prefix (if requested).
Priyesh Kumar 53be1753 2020-07-28T07:33:40 Fix `-Wformat' compiler warnings. * src/*: Fix format specifiers. * builds/unix/ftsystem.c (FT_Stream_Open): Ditto.
Werner Lemberg 16586859 2020-06-13T21:15:45 Remove redundant inclusion of `ft2build.h'. * */*: Remove `#include <ft2build.h>' where possible. * include/freetype/freetype.h: Remove cpp error about missing inclusion of `ft2build.h'.
David Turner e1339133 2020-06-08T13:31:55 Make macros for header file names optional. We no longer have to take care of the 8.3 file name limit; this allows us (a) to introduce longer, meaningful file names, and (b) to avoid macro names in `#include' lines altogether since some compilers (most notably Visual C++) doesn't support this properly. */*: Replace #include FOO_H with #include <freetype/foo.h> or something similar. Also update the documentation.

Nikhil Ramakrishnan 97616704 2019-08-14T17:39:55 [woff2] Formatting. * src/sfnt/sfobjs.c, src/sfnt/sfwoff2.c: Better formatting.
Nikhil Ramakrishnan 5367e0ca 2019-08-05T01:53:00 [sfnt] Support `face->num_faces' for WOFF2 fonts. Set correct value of `face->num_faces' for WOFF2 fonts. This is being handled separately because we only load the tables for the requested font face in `woff2_open_font' and create a single-face sfnt stream. The full discussion is at: https://lists.gnu.org/archive/html/freetype-devel/2019-08/msg00000.html * src/sfnt/sfobjs.c (sfnt_open_font): Add parameter `woff2_num_faces'. (sfnt_init_face): Introduce variable `woff2_num_faces', and change `face->root.num_faces' if `woff2_num_faces' is set. * src/sfnt/sfwoff2.c (woff2_open_font): Validate requested face index and handle negative face indices. * src/sfnt/sfwoff2.h (woff2_open_font): Add parameter `num_faces' to declaration.
Nikhil Ramakrishnan 4d9b3d1d 2019-07-16T02:45:03 [woff2] Reconstruct `loca', `hmtx', and swap out stream. Add necessary functions to reconstruct loca and hmtx tables (the two remaining tables that can have a transform). `woff2_open_font' is now capable of loading a woff2 font face. This code may still need more refining and better memory management. * include/freetype/internal/wofftypes.h (WOFF2_HeaderRec): Add total (final) size of sfnt stream. (WOFF2_InfoRec): Add header checksum value. * src/sfnt/sfobjs.c (sfnt_open_font): Change `face_instance_index' parameter to its pointer so its value can be modified by `woff2_open_font'. * src/sfnt/sfwoff2.c: (WRITE_SFNT_BUF_AT): New macro to write into sfnt buffer at given position. (write_buf): Add parameter `extend_buf' which allows caller to specify whether buffer should be reallocated before copying data. (WRITE_SFNT_BUF): Updated. (pad4, store_loca, reconstruct_htmx): New functions. (reconstruct_glyf): Calculate loca values and store them. (reconstruct_font): Call `reconstruct_hmtx', write table record entries, and calculate table checksums. Also calculate font checksum and update `checksumAdjustment' entry in head table. (woff2_open_font): Open stream for sfnt buffer, swap out input stream and return. * src/sfnt/sfwoff2.h (woff2_open_font): Modify parameter to accept pointer to `face_index'.
Nikhil Ramakrishnan fc65d45a 2019-06-30T04:31:04 [woff2] Uncompress Brotli streams and `face_index' support. WOFF2 compressed stream is now uncompressed if Brotli is available. This data is stored in a separate buffer (uncompressed_buf) because it does not contain direct table data. Certain tables have transformations applied to them, and they must be reconstructed before we can write those tables to the SFNT stream. `face_index' is now being passed as a parameter to `woff2_open_font'. * src/sfnt/sfobjs.c (sfnt_open_font): Add parameter `face_instance_index'. * src/sfnt/sfwoff2.c (woff2_uncompress): New function. (woff2_open_font): Call `woff2_uncompress'. (compute_first_table_offset): Fix return type. * src/sfnt/sfwoff2.h (woff2_open_font): Modify declaration.
Nikhil Ramakrishnan 2fa573c1 2019-06-12T00:21:20 [sfnt] Read WOFF 2 header. Check for WOFF2 tag, call `woff2_open_font', and implement it to read header according to specification. * include/freetype/internal/fttrace.h: Add `sfwoff2.c'. * src/sfnt/rules.mk (SFNT_DRV_SRC): Add `sfwoff2.c'. * src/sfnt/sfnt.c: Include `sfwoff2.c'. * src/sfnt/sfobjs.c (sfnt_open_font): Check for `wOF2' tag and call `woff2_open_font'. * src/sfnt/sfwoff2.c, src/sfnt/sfwoff2.h: New files.
Nikhil Ramakrishnan 7b275a5a 2019-05-30T23:57:34 [sfnt] Separate WOFF sources and headers. Move WOFF sources and headers to separate files. * include/freetype/internal/wofftypes.h, src/sfnt/sfwoff.c, src/sfnt/sfwoff.h: New files. * include/freetype/internal/fttrace.h: Register `sfwoff.c'. * include/freetype/internal/internal.h: Define FT_INTERNAL_WOFF_TYPES_H. * include/freetype/internal/sfnt.h: Include FT_INTERNAL_WOFF_TYPES_H. * include/freetype/internal/tttypes.h: Move out WOFF structures. * src/sfnt/rules.mk: Add `sfwoff.c'. * src/sfnt/sfnt.c: Include `sfwoff.c'. * src/sfnt/sfobjs.c: Include `sfwoff.h', move out WOFF sources.

Nikolaus Waxweiler f72b0074 2019-02-02T15:45:31 [sfnt] Use typo metrics if OS/2 fsSelection USE_TYPO_METRICS bit is set. If the OS/2 table exists and fsSelection bit 7 (USE_TYPO_METRICS) is set, use the sTypo* set of values to compute the FT_Face's ascender, descender and height. Otherwise, fall back to old behavior. * src/sfnt/sfobjs.c (sfnt_load_face): Implement.

Werner Lemberg 912e174c 2018-10-07T09:28:52 A missing Unicode cmap is not a fatal error. This is a follow-up to the previous commit. * src/cff/cffobjs.c (cff_face_init), src/sfnt/sfobjs.c (sfnt_load_face), src/type1/t1objs.c (T1_Face_Init), src/type42/t42objs.c (T42_Face_Init): Implement it.
Werner Lemberg a0dd16fb 2018-08-15T18:13:17 Don't use `trace_' prefix for FT_COMPONENT arguments. * include/freetype/internal/ftdebug.h (FT_TRACE_COMP, FT_TRACE_COMP_): New auxiliary macros to add `trace_' prefix. (FT_TRACE): Use `FT_TRACE_COMP'. */* (FT_COMPONENT): Updated.
Ben Wagner 96b5e500 2018-08-10T22:24:26 * src/sfnt/sfobjs.c (sfnt_done_face): Fix memory leak (#54435).
Werner Lemberg 8ed53468 2018-07-25T22:07:22 [psaux, type1] Trace PostScript dictionaries and other things. The tracing of /Encoding, /Subrs, and /Charstrings is rudimentary right now. * src/psaux/psobjs.c (ps_parser_load_field, ps_parser_load_field_table): Add tracing calls. * src/psaux/t1decode.c (t1_decoder_parse_charstrings): Make tracing output more compact. * src/type1/t1gload.c (T1_Compute_Max_Advance, T1_Get_Advances): Add tracing messages. * src/type1/t1load.c (parse_blend_axis_types, parse_blend_design_positions, parse_blend_design_map, parse_weight_vector, t1_load_keyword, t1_parse_font_matrix, parse_encoding, parse_subrs, parse_charstrings, T1_Open_Face): Add tracing calls. * src/type1/t1objs.c (T1_Face_Init): Add tracing call. * src/sfnt/sfobjs.c (sfnt_init_face): Make tracing message more verbose.

Werner Lemberg 54b332aa 2018-06-13T08:46:27 [sfnt] Separate `CPAL' and `COLR' table handling. Later on we want to support the `SVG' table also, which needs `CPAL' (but not `COLR'). * include/freetype/internal/sfnt.h (SFNT_Interface): Add `load_cpal' and `free_cpal' fields. (FT_DEFINE_SFNT_INTERFACE): Updated. * include/freetype/internal/tttypes.h (TT_FaceRec): Replace `colr_and_cpal' fields with `cpal' and `colr'. * src/sfnt/sfdriver.c (sfnt_interface): Updated. * src/sfnt/sfobjs.c (sfnt_load_face, sfnt_done_face): Updated. * src/sfnt/ttcolr.c (Colr, Cpal): Add `table' field. (ColrCpal): Removed. (tt_face_load_colr): Split off CPAL handling into... (tt_face_load_cpal): ... this new function. (tt_face_free_colr): Split off CPAL handling into... (tt_face_free_cpal): ... this new function. (tt_face_load_colr_layers, tt_face_palette_set): Updated. * src/sfnt/ttcolr.h: Updated. * src/truetype/ttgload.c (TT_Load_Glyph): Updated.
Werner Lemberg b85d4e8f 2018-06-12T05:53:58 Finish CPAL/COLR support (2/4). * src/sfnt/ttcolr.c (tt_face_palette_set): New function. (tt_face_load_colr): Allocate `face->palette' and call `tt_face_palette_set'. Adjust return error code in case of error. * src/sfnt/ttcolr.h: Updated. * include/freetype/internal/sfnt.h (TT_Set_Palette_Func): New function type. (SFNT_Interface, FT_DEFINE_SFNT_INTERFACE): Add it. * src/sfnt/sfdriver.c (sfnt_interface), src/sfnt/sfobjs.c (sfnt_done_face): Updated.

Werner Lemberg 9ac9060d 2018-06-03T09:01:17 [GSoC] src/*.*: Convert block comments to `light' style. This monster commit was created by applying Nikhil's scripts `docconverter.py' and `markify.py' to all C header and source files, followed up by minor manual clean-up. No change in functionality, of course. I used commit f7419907bc6044b9b7057f9789866426c804ba82 from https://github.com/nikramakrishnan/freetype-docs.git.
Shao Yu Zhang f04d8175 2018-05-13T03:25:09 [sfnt] Preliminary support of coloured layer outlines. 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.

suzuki toshiya 5c4e40d7 2017-09-09T00:59:33 [sfnt, truetype] Register the tags for marginal fonts. The first 32bit of standard TrueType variants is 0x00010000, `OTTO', `ttcf', `true' or `typ1'. 2 marginal dfonts on legacy Mac OS X, Keyboard.dfont and LastResort.dfont, have the sfnt resources starting 0xA5 followed by `kbd' or `lst'. Considering the following data could be parsed as conventional TrueType fonts, the header checking is updated to allow these tags. It seems that recent Mac OS X has already switched to normal TTF for these fonts. See the discussion at http://u88.n24.queensu.ca/exiftool/forum/index.php?topic=3931.0 * include/freetype/tttags.h (TTAG_0xA5kbd, TTAG_0xA5lst): New header tags for Keyboard.dfont and LastResort.dfont. * src/sfnt/sfobjs.c (sfnt_open_font): Accept the sfnt resource starts with TTAG_0xA5kbd or TTAG_0xA5lst. * src/truetype/ttobjs.c (tt_face_init): Accept the face with the format tag is TTAG_0xA5kbd or TTAG_0xA5lst.
Alexei Podtelezhnikov 7653c765 2017-08-17T21:28:32 [sfnt] Avoid synthetic unicode for symbol fonts with PUA. Reported as https://bugs.chromium.org/p/chromium/issues/detail?id=754574 * src/sfnt/sfobjs.c (sfnt_load_face): Check for FT_ENCODING_MS_SYMBOL.
Werner Lemberg ce367774 2017-08-01T08:24:51 [sfnt, truetype] Minor adjustments for OpenType 1.8.2. * src/sfnt/sfobjs.c (sfnt_load_face): The units per EM value has now (tighter) limits. * src/truetype/ttgload.c (load_truetype_glyph): The new OpenType version explicitly allows all negative values for the number of contours if we have a composite glyph (this is for better backwards compatibility I guess), but it still recommends value -1.

Werner Lemberg 77930974 2017-03-07T17:27:58 [sfnt] Improve handling for buggy variation fonts. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=738 * src/sfnt/sfobjs.c (sfnt_init_face): While setting number of instances to zero for `CFF' fonts table, ensure that there is no `glyf' present also (which gets priority).
Werner Lemberg 27fee7f8 2017-03-06T20:45:44 [sfnt, truetype] Always provide default instance. As documented in the OpenType specification, an entry for the default instance may be omitted in the named instance table. In particular this means that even if there is no named instance table in the font we actually do have a named instance, namely the default instance. For consistency, we always want the default instance in our list of named instances. If it is missing, we try to synthesize it. * src/sfnt/sfobjs.c (sfnt_init_face): Check whether the default instance is in the table of named instances. Otherwise adjust number of instances. * src/truetype/ttgxvar.c: Include FT_TRUETYPE_IDS_H. (TT_Get_MM_Var): Use `face->root.style_flags' as the number of named instances. Sythesize a named instance entry if necessary. (tt_done_blend): Free `normalized_stylecoords'.

(WRITE_BYTE, WRITE_USHORT, WRITE_ULONG): New temporary macros for writing to a stream. (sfnt_stream_close, compare_offsets, woff_open_font): New functions. (sfnt_open_font): Handle `TTAG_wOFF'. (sfnt_init_face): Set `stream' after calling `sfnt_open_font'. * src/truetype/ttobjs.c (tt_face_init): Set `stream' after calling `sfnt->init_face'. * src/base/ftobjs.c (open_face): Use a pointer to FT_Stream as an argument so that a changed stream survives. Update callers.
