Werner Lemberg f7d7e7f9f7 freetype.h: Documentation typos. 2021-02-27 12:14:02 +01:00
Dominik Röttsches 215ae25330 [sfnt] Update paint format values to support non-variable paints.
* freetype.h (FT_PaintFormat): Update paint format identifiers after
a specification change.  The specification was updated to have
sibling formats, variable and non-variable variants for each.
Reflect that here.

* sfnt/ttcolr.c (read_paint): Remove parsing of variable indices as
the non-variable formats no longer have them.
2021-02-16 13:15:41 +01:00

Werner Lemberg 324612ceb2 Always provide logging API.
It's easier to have stubs if FT_DEBUG_LOGGING is undefined than to
modify `ftexport.sym` conditionally.

Problem reported by Alexei.

* src/base/ftdebug.c: Include `ftlogging.h`.

(FT_Trace_Set_Level, FT_Trace_Set_Default_Level, FT_Set_Log_Handler,
FT_Set_Default_Log_Handler) [!FT_DEBUG_LOGGING]: Provide stubs.

Dominik Röttsches 53fea87745 Add config option to test for 'COLR' v1 support in headers.
* include/freetype/config/ftoption.h (TT_SUPPORT_COLRV1): New macro
so that clients can test whether the FreeType checkout that they are
building against supports the 'COLR' v1 API.  This is intended to be
a temporary solution until 'COLR' v1 support is released in a
FreeType version and such a check can be made by using the version
number instead.

Chris Liddell f6be92767d [truetype] Fix incremental metrics (#59503).
* src/truetype/ttgload.c (tt_get_metrics, load_truetype_glyph):
Previously, the code would populate the phantom points before
calling the `get_glyph_metrics` callback.  For formats like PCL XL
format 1, class 2 downloaded fonts (where metrics are removed from
the TTF header), this causes problems when the hinting program uses
the phantom points (misplaced and distorted glyphs) due to the
metrics being unset (all zeros).
(tt_get_metrics_incr_overrides): Renamed to...
(tt_get_metrics_incremental): ... this.  Updated caller

* include/freetype/ftincrem.h: Update the documentation to make it
clearer that `get_glyph_metrics` is to retrieve metrics from a
non-standard source, but *not* for the purpose of imposing custom
metrics.
