| | | | | | | | | | Otherwise we get zillions of clang 15 warnings. * src/autofit/afcjk.c, src/autofit/afhints.c, src/autofit/aflatin.c, src/base/ftobjs.c, src/base/ftoutln.c, src/cff/cffparse.c, src/raster/ftraster.c, src/sfnt/pngshim.c, src/truetype/ttgload.c, src/truetype/ttgxvar.c, src/truetype/ttobjs.c, src/type1/t1gload.c: Use `double` cast in debugging and tracing macros.

* [autofit] Don't depend on 'hb-ft'.Matthias Clasen2023-01-065-2/+144
| | | | | | | | | | | | | | | | 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.
* * src/autofit/afloader.c (af_loader_load_glyph): Remove `size` check.Alexei Podtelezhnikov2022-11-201-6/+1

* [autofit, pshinter] Use `FT_OFFSET`.Werner Lemberg2022-01-073-13/+13
| | | | | | | | | | | | | | | | | | | | | | | This avoids ``` runtime error: applying zero offset to null pointer ``` warnings of clang's undefined behaviour sanitizer. * src/autofit/afcjk.c (af_cjk_hints_link_segments, af_cjk_hints_compute_edges, af_cjk_hints_compute_blue_edges, af_cjk_hint_edges, af_cjk_align_edge_points): Do it. * src/autofit/afhints.c (af_glyph_hints_align_edge_points, af_glyph_hints_align_strong_points): Ditto. * src/autofit/aflatin.c (af_latin_metrics_init_widths, af_latin_hints_link_segments, af_latin_hints_compute_edges, af_latin_hints_compute_blue_edges, af_latin_hint_edges): Ditto. * src/pshinter/pshalgo.c (psh_hint_table_init): Ditto.

* [autofit] Split `afwrtsys.h`.Ben Wagner2021-07-245-34/+47
| | | | | | | | | | | | | | | | | | | | | | | | | 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.
* [autofit] More clean-ups.Werner Lemberg2021-07-123-8/+2
| | | | | | | | * src/autofit/afhints.h (AF_GlyphHintsRec): Remove the no longer needed fields `xmin_delta` and `xmax_delta`. * src/autofit/afhints.c (af_glyph_hints_reload), src/autofit/afloader.c (af_loader_load_glyph): Updated.
* Remove obsolete AF_Angle type and related sources.David Turner2021-07-126-352/+99
| | | | | | Move the af_sort_xxx() functions from afangles.c to afhints.c in order to get rid of the obsolete angle-related types, macros and function definitions.
* Remove experimental auto-hinting 'warp' mode.David Turner2021-07-1212-606/+0
| | | | | | | 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.
* Remove experimental "Latin2" writing system (FT_OPTION_AUTOFIT2)David Turner2021-07-126-2497/+0
| | | | | | 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).
* Prevent hinting if there are too many segments.Werner Lemberg2021-06-191-0/+25
| | | | | | | | | | | This speeds up handling of broken glyphs. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=35309 * src/autofit/aflatin.c (af_latin_hints_compute_segments): Implement it.
* Fix for issue 1063David Turner2021-06-161-0/+4

* [autofit] Fix double division in stem darkening.Tatsuyuki Ishi2020-12-182-16/+13
| | | | | | | | | | | | | | | 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.
* * src/*: More fixes for using a '\n' in `FT_TRACE` and `FT_ERROR`.Werner Lemberg2020-12-071-17/+16
|
* * src/*: Don't use more than one '\n' in `FT_TRACE` and `FT_ERROR`.Werner Lemberg2020-12-056-54/+59
| | | | | This ensures good logging output, with all lines having a proper prefix (if requested).
* Downgrade property tracing.Alexei Podtelezhnikov2020-11-201-3/+3

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * include/freetype/internal/autohint.h (FT_DECLARE_AUTOHINTER_INTERFACE): New macro. * src/autofit/afmodule.h: Use it to declare `af_autofitter_interface'. * include/freetype/internal/ftobjs.h (FT_DECLARE_GLYPH): New macro. * src/base/ftbase.h: Use it to declare `ft_bitmap_glyph_class' and `ft_outline_glyph_class'. * src/base/ftglyph.c: Include `ftbase.h'. * src/cff/cffparse.c (cff_parser_run): Fix type of `t2_size'. * src/pcf/pcfdrivr.c (pcf_cmap_char_next): Fix type of `result'. * src/psaux/psauxmod.c (psaux_module_class): Use `FT_DEFINE_MODULE'. * src/psaux/psauxmod.h: Declare `afm_parser_funcs', `t1_cmap_classes', `cff_decoder_funcs', and `psaux_module_class'. * src/pshinter/pshmod.c: Include `pshmod.h'. * src/sfnt/sfwoff2.c (ROUND4, WRITE_SHORT): Fix implicit sign conversion. (compute_ULong_sum): Fix return type. Fix implicit sign conversion. (store_points): Fix type of `last_flag', `repeat_count', and `flag'. Use casts to avoid warnings.

* Make macros for header file names optional.David Turner2020-06-0812-24/+24
| | | | | | | | | | | | | | | | | 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.
* Remove Jamfile files from the tree.David Turner2020-05-181-53/+0
| | | | | | | | These have not been used in a very, very long time, so better remove them. A corresponding patch will be submitted to the `freetype2-demos' repository. * src/Jamfile, src/*/Jamfile, Jamrules: Delete.
* [autofit] Add support for Hanifi Rohingya script.Nikolaus Waxweiler2020-02-196-41/+93
