a64b49cc | 2025-04-20 08:00:26 | [autofit] Request at least HarfBuzz 7.2.0 for diacritic support. (3/3) This version (from April 2023) added 'SingleSubst' support to `hb_ot_layout_lookup_get_glyph_alternates`. | |

573201be | 2025-04-20 06:27:52 | [autofit] Speed up creation of the adjustment database's reverse map. (1/3) As it turns out, the original implementation using `hb_ot_shape_glyphs_closure` is extremely slow if a font has a rich set of OpenType features. For example, this function was called 66954 times while loading font `arial.ttf` version 7.00, increasing FreeType's startup time by a factor of 10, which is unacceptable. The new algorithm uses a completely different, more low-level approach, no longer working with OpenType features but with OpenType lookups. It relies on function `hb_ot_layout_lookup_get_glyph_alternates`, also replacing recursion with a simple loop. In total, this brings the additional startup time back to an acceptable range of a few percent. A side effect of the new approach is that it catches more alternate forms: the old code didn't properly handle script-specific features. To make the change more readable, this commit only adds new code. | |

dc55f4e6 | 2025-04-14 21:03:08 | [autofit] Avoid unnecessary recomputation of HarfBuzz data. Call the functions once per font instead of once per glyph. * src/autofit/afadjust.c (af_all_glyph_variants): Move code to compute the `feature_tags` and `type_3_lookup_indices` sets to... (af_reverse_character_map_new): ...this function. | |
|
d1ac9524 | 2025-04-14 15:48:33 | [autofit] Fix creation of the adjustment database's reverse map. Due to the way the reverse map array gets constructed with HarfBuzz, there might be multiple, identical glyph index entries with different character values in the array. As an example, an OpenType feature like 'unic' might map lowercase glyph 'ae' to uppercase glyph 'AE', in addition to the already present cmap entry for 'AE'. In most cases, this incorrect mapping is harmless (but still wrong). However, there exist some lowercase/uppercase character pairs where the diacritic for the uppercase character is on the other vertical side of the base character as for the lowercase character. An example is U+0122 (LATIN CAPITAL LETTER G WITH CEDILLA) and U+0123 (LATIN SMALL LETTER G WITH CEDILLA): the former has the cedilla below, the latter above. A wrong mapping would thus shift the base glyph 'G' up by a pixel instead of shifting the cedilla down. We fix this by always giving precedence to cmap entries. * src/autofit/afadjust.c (af_reverse_character_map_entry_compare): Do a secondary sort on the character code. (af_reverse_character_map_lookup): Adjust binary search to return the first occurrence of an entry (i.e., the one with the lowest array index). (af_reverse_character_map_new)[FT_CONFIG_OPTION_USE_HARFBUZZ]: Implement cmap priority. | |
|

|
52d4573e | 2025-04-11 07:30:55 | [autofit] Better vertical separation adjustment support. (1/2) Test vertical maxima instead of vertical minima to identify the highest contour (and vice versa to identify the lowest contour). Doing so will allow support of diacritics that consist of more than a single outline. This works because of the topological constraints ensured by the adjustment database. * src/autofit/aflatin.c (af_find_highest_contour, af_glyph_hints_apply_vertical_separation_adjustments): Implement it. | |
|

 |
24ac6c5d | 2024-01-29 08:37:54 | [autofit] Add GSUB table handling to reverse character map generation.

044d142b | 2024-06-20 22:16:51 | Use unsigned tags `FT_Outline`. This change comes along with 2a7bb4596f56 ans is only meant to reduce pointer casting in the code. * include/freetype/ftimage.h (FT_Outline): Do it. * src/*: Update `FT_Outline` users. | |
|
2a7bb459 | 2024-06-20 20:49:56 | Use unsigned point and contour indexing in `FT_Outline`. This doubles the number or allowed points, see https://github.com/harfbuzz/harfbuzz/issues/4752 Although it is hardly practical to use more than 32767 points, other font engines seem to support it. * docs/CHANGES: Announce it. * include/freetype/ftimage.h (FT_Outline): Do it and update limits. * src/*: Update `FT_Outline` users. | |

45903920 | 2023-09-05 08:07:17 | [autofit] Fix synchronization mistake between FreeType and ttfautohint. Found by Behdad. * src/autofit/aflatin.c (af_latin_metrics_init_blues): Fix array size of `blue_sorted`: FreeType doesn't have artificial blue zones. | |
|
ad201739 | 2023-09-04 19:22:43 | [autofit] Fix typos. This also reduces the used heap size by a large factor. From Behdad. * src/autofit/afcjk.h (AF_CJKAxisRec): Use `AF_BLUE_STRINGSET_MAX_LEN`. * src/autofit/aflatin.h (AF_LatinAxisRec): Ditto. | |
|
a20de84e | 2023-08-12 11:47:41 | Fix warnings in tracing messages for 32bit compilation. Since we now require C99, use `%td` for `ptrdiff_t` and `%zu` for `size_t`. | |
 |
7bed7a02 | 2023-06-01 21:05:32 | Fix some `FT_Fixed` vs. `FT_Long` confusion. `FT_Fixed` and `FT_Long` are both typedef'ed to be `signed long`. However, `FT_Fixed` implies that the lower 16 bits are being used to express fractional values and so these two types should not be confused. * include/freetype/internal/services/svmm.h (FT_Set_MM_Blend_Func): Use `FT_Fixed` for `coords`. Users are passing `FT_Fixed` and implementations are taking `FT_Fixed`. (FT_Get_MM_Blend_Func): Ditto. * src/autofit/afcjk.c (af_cjk_metrics_check_digits): Use `FT_Long` for `advance` and `old_advance`. `advance`'s address is passed as `FT_Long*` to `af_shaper_get_elem`, which writes the advance in em units (not fixed). The exact value is not important here as it is only compared to check whether it has changed. * src/autofit/aflatin.c (af_latin_metrics_check_digits): Ditto. | |
|
2fb8eda5 | 2023-06-01 19:38:36 | */*: Remove many function pointer casts. In C it is undefined behavior to call a function through a function pointer of a different type. This is now detected by the Control Flow Integrity Sanitizer. All known issues have already been fixed. Prevent any accidental re-introduction by removing function pointer casts when defining services. The services will call the service functions through the function pointers on the service. As a result the functions must have the same type so there should be no need to cast. Removing the casts allows compilers to warn about assignment to an incompatible function pointer type. | |

80a507a6 | 2023-05-23 13:13:56 | Replace `sprintf` with `snprintf`. Fixes #1233. * include/freetype/config/ftstdlib.h (ft_sprintf): Replace with...

(af_glyph_hints_dump_points, af_glyph_hints_dump_segments, af_glyph_hints_dump_edges): Updated. * src/bdf/bdflib.c (BUFSIZE): New macro. (bdf_parse_properties_, bdf_parse_start_): Use `ft_snprintf`. * src/tools/ftrandom/ftrandom.c (do_test): Use `snprintf`. | |
|
5edd6d52 | 2023-05-08 07:22:59 | Minor compiler warning fixes. * src/autofit/afcjk.c (af_cjk_get_standard_widths), src/autofit/aflatin.c (af_latin_get_standard_widths): Use `FT_CALLBACK_DEF`. * src/cff/cffparse.c (cff_parser_run): Initialize and fix allocation of `q`. | |

|
37bc7c26 | 2023-02-07 07:37:07 | Avoid reserved identifiers that are globally defined. This is mandated by the C99 standard, and clang 15 produces zillions of warnings otherwise. * devel/ftoption.h, include/freetype/config/ftoption.h, include/freetype/internal/ftmemory.h, src/autofit/afhints.h, src/autofit/afmodule.c, src/autofit/aftypes.h, src/base/ftadvanc.c, src/base/ftdbgmem.c, src/base/ftstream.c, src/bdf/bdflib.c, src/truetype/ttinterp.c: Replace identifiers of the form `_foo` with `foo_`. | |

ebe7e912 | 2023-01-02 20:13:22 | [autofit] Don't depend on 'hb-ft'. The circular dependency is still there, but at least we no longer depend on the HarfBuzz API that is only present if HarfBuzz has been built with FreeType support, making the bootstrapping a bit easier. * src/autofit/ft-hb.c, src/autofit/ft-hb.h: New files, providing `_hb_ft_font_create`, which is more or less a verbatim copy of the corresponding HarfBuzz code from file `hb-ft.cc`. * src/autofit/afglobal.c (af_face_globals_new): Use it. * src/autofit/afshaper.h: Don't include `hb-ft.h` but `ft-hb.h`. * src/autofit/autofit.c: Include `ft-hb.c`. * LICENSE.TXT: Updated. | |

5bcaf51b | 2021-07-23 11:59:58 | [autofit] Split `afwrtsys.h`. The header file `afwrtsys.h` has two distinct functions: to include the required writing system headers and also to generate code for each writing system. At each current use site only one or the other is used, with various macro trickery selecting one or the other. Split this header into `afws-decl.h` for the required writing system declarations and `afws-iter.h` for iterating over the writing systems to generate code. The motivation for this change is that the Visual C++ compiler treats the standard include guard idiom like `#pragma once` 'if no non-comment code or preprocessor directive comes before or after the standard form of the idiom'. It appears to check this after macro expansion, so if `WRITING_SYSTEM` expands to empty the bottom of `afwrtsys.h` is empty and looks like the standard include guard idiom which is treated like `#pragma once`, so subsequent inclusion of `afwrtsys.h` is elided. Fixes #1075. * src/autofit/afglobal.c (af_writing_system_classes), src/autofit/aftypes.h (AF_WritingSystem), src/autofit/rules.mk (AUTOF_DRV_H): Updated. * src/autofit/afwrtsys.h: Split into... * src/autofit/afws-decl.h, src/autofit/afws-iter.h: New files. | |

2f11522a | 2021-06-02 19:05:09 | Remove experimental auto-hinting 'warp' mode. This feature was always experimental, and probably nevery worked properly. This patch completely removes it from the source code, except for a documentation block describing it for historical purpose. | |
|
15e88980 | 2021-06-02 18:54:41 | Remove experimental "Latin2" writing system (FT_OPTION_AUTOFIT2) This code has always been experimental and was never compiled anyway (FT_OPTION_AUTOFIT2 does not appear in ftoption.h or even any of our build files). | |

0d5f1dd3 | 2020-12-18 22:10:30 | [autofit] Fix double division in stem darkening. The old code used to divide the darkening amount by em_ratio twice, leading to unnecessarily bold stems on certain fonts with higher units per em (e.g. Inter). This patch fixes it. The return value of af_loader_compute_darkening was also changed to use 16.16 fixed point to get rid of a redundant truncation operation. This should slightly improve the precision, although it's still bottlenecked by the emboldening function, which uses 26.6 fixed point. * src/autofit/afloader.[ch] (af_loader_compute_darkening): Return FT_Fixed. (af_loader_embolden_glyph_in_slot): Revise calculations. | |

272ae5ee | 2020-12-07 10:29:24 | * src/*: More fixes for using a '\n' in `FT_TRACE` and `FT_ERROR`. | |
|
a6adb256 | 2020-12-02 14:15:07 | * 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). | |

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. | |
