97bb53ee | 2025-04-28 07:24:41 | [autofit] Enable dynamic loading of HarfBuzz. (2/2) Handle the case where loading HarfBuzz dynamically fails. * src/autofit/ft-hb.c, src/autofit/ft-hb.h (ft_hb_enabled): New function. * src/autofit/afglobal.c (af_face_globals_new, af_face_globals_free): Guard HarfBuzz functions with `ft_hb_enabled`. * src/autofit/aflatin.c (af_latin_metrics_init_widths, af_latin_metrics_init_blues, af_latin_metrics_check_digits): Simplify setup of `shaper_buf`. Guard calls of `af_shaper_buf_create` with `ft_hb_enabled`. * src/autofit/afcjk.c (af_cjk_metrics_init_widths, af_cjk_metrics_init_blues, af_cjk_metrics_check_digits): Dito. * src/autofit/afshaper.c: Guard all HarfBuzz function calls with `ft_hb_enabled`. | |

7651fe00 | 2025-04-27 18:44:49 | [autofit] Enable dynamic loading of HarfBuzz. (1/2) This commit activates the mini-HarfBuzz header files and provides the necessary infrastructure for dynamically loading HarfBuzz if `FT_CONFIG_OPTION_USE_HARFBUZZ_DYNAMIC` is defined (this macro gets set up in a follow-up commit). * src/autofit/ft-hb.c: New file, providing `ft_hb_funcs_init` and `ft_hb_funcs_done` for loading HarfBuzz dynamically. The name of the library is hold in the macro `FT_LIBHARFBUZZ`, which can be overridden. * src/autofit/ft-hb.h: Don't include `hb.h` but `ft-hb-types.h`. (hb): Modified to handle both standard linking and dynamically loading of HarfBuzz. (HB_EXTERN): New macro to load `ft-hb-decls.h`. * src/autofit/afadjust.c [FT_CONFIG_OPTION_USE_HARFBUZZ]: For the sake of dynamically loading the HarfBuzz library, replace the compile-time macro `HB_VERSION_ATLEAST` with a call to the run-time function `hb_version_atleast` where necessary – a follow-up commit will set the minimum version of HarfBuzz to 2.6.8, which provides all necessary functions needed by FreeType. * src/autofit/afmodule.h: Include `ft-hb.h`. (AF_ModuleRec) [FT_CONFIG_OPTION_USE_HARFBUZZ_DYNAMIC]: Add `hb_funcs` structure to hold pointers to the dynamically loaded HarfBuzz functions. * src/autofit/afmodule.c (af_autofitter_init, af_autofitter_done) [FT_CONFIG_OPTION_USE_HARFBUZZ_DYNAMIC]: Call `ft_hb_funcs_init` and `ft_hb_funcs_done`. * src/autofit/afshaper.h: Updated. * src/autofit/autofit.c: Include `ft-hb.c`. * src/autofit/rules.mk (AUTOF_DRV_SRC, AUTOF_DRV_H): Updated. | |
|
9242c88f | 2025-04-26 21:46:51 | [autofit] Some preparations for loading HarfBuzz dynamically. (3/4) * src/autofit/afshaper.c: Move around code so that the non-HarfBuzz code is present even if `FT_CONFIG_OPTION_USE_HARFBUZZ` is not defined. This is a preliminary step to allow deactivation of HarfBuzz at run-time. | |
|
e9d03072 | 2025-04-26 19:05:31 | [autofit] Some preparations for loading HarfBuzz dynamically. (2/4) Pass `AF_FaceGlobals` to many functions, or provide it, tagged with `FT_UNUSED`. We need this later on to access a dynamically linked HarfBuzz library. * src/autofit/ft-hb-ft.h (ft_hb_ft_font_create): Use `globals` argument. Drop unused `destroy` argument. * src/autofit/ft-hb-ft.c (ft_hb_ft_face_create, ft_hb_ft_font_create): Use `globals` argument. Drop unused `destroy` argument. (ft_hb_ft_face_create, ft_hb_ft_reference_table): Cast `user_data` to `AF_FaceGlobals`. * src/autofit/afadjust.c (af_get_glyph_alternates_helper, af_get_glyph_alternates): Add `globals` argument. Update callers. * src/autofit/afshaper.c, src/autofit/afshaper.h (af_shaper_buf_create, af_shaper_buf_destroy): Use `globals` argument. * src/autofit/afglobal.c (af_face_globals_new): Updated. * src/autofit/afcjk.c (af_cjk_metrics_init_widths, af_cjk_metrics_init_blues, af_cjk_metrics_check_digits): Updated. * src/autofit/aflatin.c (af_latin_metrics_init_widths, af_latin_metrics_init_blues, af_latin_metrics_check_digits): Updated. | |

b512ce3e | 2025-04-26 22:31:22 | [autofit] Some preparations for loading HarfBuzz dynamically. (4/4) Add 'mini' HarfBuzz declarations to make FreeType independent on HarfBuzz header files. The files get activated in a follow-up commit. * src/autofit/ft-hb-decls.h, src/autofit/ft-hb-types.h: New files, holding verbatim (or slightly massaged) entries from public HarfBuzz header files. * src/autofit/hb-script: New file. A verbatim copy of a public HarfBuzz header file. | |
|
8b443d70 | 2025-04-26 12:22:23 | [autofit] Some preparations for loading HarfBuzz dynamically. (1/4) * src/autofit/ft-hb.h: New file, defining the `hb` macro. Later on, we provide a different definition of this macro depending on a yet-to-come configuration option to support dynamic loading of HarfBuzz functions. * src/autofit/afadjust.c, src/autofit/afglobal.c, src/autofit/afshaper.c, stc/ft-hb-ft.c: Use it. | |

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`. | |
|
de98b1ba | 2025-04-20 07:32:05 | [autofit] Speed up creation of the adjustment database's reverse map. (2/3) Remove the old code and activate the new one. | |
|
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. | |

|
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. | |

d0c905c6 | 2025-02-24 19:13:39 | [sfnt/CPAL] Return early if user requested currently-set palette Before, we were loading a palette (again and again) even if the same was requested. Even if the font only had one palette... For a font like NotoColorEmoji that has over 5000 colors in its palette, this was dominating the COLRv1 loading times for HarfBuzz (and I believe all other clients) because they have to set the palette to get access to the colors. * src/base/ftcolor.c (FT_Palette_Select): Check the current palette. | |
|
b1f47850 | 2025-01-28 22:49:21 | * src/bdf/bdflib.c (bdf_parse_start_): Move setup of properties. | |

|
01c22b36 | 2025-01-19 11:19:10 | [bdf] Tokenize input instead of listing.
