* include/freetype/freetype.h (FREETYPE_PATCH): Set to 2.
* builds/unix/configure.raw (version_info): Set to 18:2:12.
* CMakeLists.txt (VERSION_PATCH): Set to 2.
* docs/CHANGES: Updated.
In the reference, we show the section's title enclosed in single
quotes.
* src/tools/docmaker/formatter.py (Formatter::__init__): Collect
section names as identifiers.
* src/tools/docmaker/tohtml.py (section_title_header): Split into...
(section_title_header1, section_title_header2): ... these two
strings.
(HtmlFormatter::make_block_url, make_html_word, html_source_quote):
Handle sections.
(HtmlFormatter::section_enter): Updated to add `id' HTML attribute.
We need this to handle equally named properties in different
modules.
* src/tools/docmaker/content.py (re_identifier),
src/tools/docmaker/sources.py (re_crossref): Allow `foo[bar]'.
* src/tools/docmaker/tohtml.py (HtmlFormatter::make_html_word,
HtmlFormatter::index_exit, HtmlFormatter::section_enter,
HtmlFormatter::block_enter): Handle `foo[bar]'.
This does the same as `FT_LCD_FILTER_LEGACY'.
See
https://bugs.freedesktop.org/show_bug.cgi?id=92981
for the reasoning.
* include/freetype/ftlcdfil.h (FT_LcdFilter): New value
`FT_LCD_FILTER_LEGACY1'.
* src/base/ftlcdfil.c (FT_Library_SetLcdFilter): Use it.
Both the native CFF hinter and the auto-hinter now have a very
similar rendering style.
* include/freetype/freetype.h: Mention that FT_LOAD_TARGET_LIGHT no
longer implies FT_LOAD_FORCE_AUTOHINT.
* include/freetype/ftmodapi.h (FT_MODULE_DRIVER_HINTS_LIGHTLY): New
macro.
* include/freetype/internal/ftobjs.h (FT_DRIVER_HINTS_LIGHTLY): New
macro.
* src/cff/cffdrivr.c (cff_driver_class): Use it.
* src/base/ftobjs.c (FT_Load_Glyph): Update auto-hinter selection
logic.
* src/autofit/aflatin.h (AF_LatinBlueRec): Add `ascender' and
`descender' fields.
* src/autofit/aflatin.c (af_latin_metrics_init_blues): Collect
ascender and descender data for blue zones.
(af_latin_metrics_scale_dim): Reject vertical scaling values that
change the result by more than two pixels.
* include/freetype/internal/tttypes.h (TT_LoaderRec): New field
`composites'.
* src/truetype/ttgload.c: Include FT_LIST_H.
(load_truetype_glyph): Add composite subglyph index to a list;
abort if index is already in list.
(tt_loader_init): Updated.
(tt_loader_done): New function.
(TT_Load_Glyph): Call `tt_loader_done'.
This is a crude adaption of the original `cf2_computeDarkening'
function.
* src/autofit/afloader.c (af_intToFixed, af_fixedToInt,
af_floatToFixed): New macros, taken from `cf2fixed.h'.
(af_loader_compute_darkening): New function.
* src/autofit/afloader.h: Updated.
We need the computed standard horizontal and vertical widths for the
emboldening calculation. This method provides a convenient way to
extract it from writing-system-specific metrics structures, which
all script definitions must implement.
* src/autofit/aftypes.h (AF_WritingSystem_GetStdWidthsFunc): New
function type.
(AF_WritingSystemClassRec): New member `style_metrics_getstdw'.
(AF_DEFINE_WRITING_SYSTEM_CLASS): Updated.
* src/autofit/afcjk.c (af_cjk_get_standard_width): New function.
(af_cjk_writing_system_class): Updated.
* src/autofit/afdummy.c (af_dummy_writing_system_class): Updated.
* src/autofit/afindic.c (af_cjk_get_standard_width): New function.
(af_indic_writing_system_class): Updated.
* src/autofit/aflatin.c (af_latin_get_standard_width): New function.
(af_indic_writing_system_class): Updated.
* src/autofit/aflatin.c (af_latin_get_standard_width): New function.
(af_indic_writing_system_class): Updated.
Actual code follows in a later commit.
* include/freetype/ftautoh.h: Document `no-stem-darkening' and
`darkening-parameters'.
* src/autofit/afmodule.h: New fields `no_stem_darkening' and
`darken_params'.
* src/autofit/afmodule.c (af_property_set, af_property_get):
Handle them.
(af_autofitter_init): Initialize them.
Currently, libFuzzer only supports mutation of a single file. We
circumvent this problem by using an uncompressed tar archive as
multiple-file input for the fuzzer.
This patch enables tests of `FT_Attach_Stream' and AFM/PFM parsing;
a constructed tarball should contain a font file as the first
element, and files to be attached as further elements.
* src/tools/ftfuzzer/ftfuzzer.cc: Include libarchive headers.
(archive_read_entry_data, parse_data): New functions.
(LLVMFuzzerTestOneInput): Updated.
* src/tools/ftfuzzer/ftmutator.cc: New file, providing a custom
mutator for libFuzzer that can mutate tarballs in a sensible way.
* src/autofit/afhints.c (af_print_idx, af_get_segment_index,
af_get_edge_index): New functions.
(af_glyph_hints_dump_points): Remove unnecessary `|', `[', and `]'.
Add segment and edge index for each point.
Slightly change printing order of some elements.
Don't print `-1' but `--' for missing elements.
(af_glyph_hints_dump_segments, af_glyph_hints_dump_edges): Remove
unnecessary `|', `[', and `]'.
Don't print `-1' but `--' for missing elements.
Problem reported by Nikolay Sivov <bunglehead@gmail.com>.
* src/sfnt/ttsbit.c (tt_face_load_strike_metrics): Avoid zero value
for `metrics->height' by applying some heuristics.
This modifies the addition of subroutine number to subroutine bias
from unsigned to signed, but does not change any results.
* src/cff/cf2ft.c (cf2_initGlobalRegionBuffer,
cf2_initLocalRegionBuffer): Change variable names from (unsigned)
`idx' to (signed) `subrNum', since it is not an index until after
the bias is added.
* src/cff/cf2ft.h: Updated.
* src/cff/cf2intrp.c (cf2_interpT2CharString) <cf2_cmdCALLSUBR>:
Updated similarly.
