16586859 | 2020-06-13 21:15:45 | 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'. | |
 |
e1339133 | 2020-06-08 13:31:55 | 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. | |

97616704 | 2019-08-14 17:39:55 | [woff2] Formatting. * src/sfnt/sfobjs.c, src/sfnt/sfwoff2.c: Better formatting. | |
|
5367e0ca | 2019-08-05 01:53:00 | [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. | |
|
4d9b3d1d | 2019-07-16 02:45:03 | [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'. | |
|
fc65d45a | 2019-06-30 04:31:04 | [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. | |
|
2fa573c1 | 2019-06-12 00:21:20 | [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. | |
|
7b275a5a | 2019-05-30 23:57:34 | [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. | |

54b332aa | 2018-06-13 08:46:27 | [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.

9ac9060d | 2018-06-03 09:01:17 | [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. | |

f04d8175 | 2018-05-13 03:25:09 | [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'.

5c4e40d7 | 2017-09-09 00:59:33 | [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. | |

ce367774 | 2017-08-01 08:24:51 | [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. | |

27fee7f8 | 2017-03-06 20:45:44 | [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'. | |
