Alexei Podtelezhnikov 32f13c11a4 [truetype] Quietly reject out-of-spec `hdmx` tables.
The `hdmx` table is optional and can be safely rejected without
an error if it does not follow specifications. The record size
must be equal to the number of glyphs + 2 + 32-bit padding.

* src/truetype/ttpload.c (tt_face_load_hdmx): Thoroughly check
the record size and improve tracing.
2021-11-25 22:38:40 -05:00

`record_size` is rounded even though the records are padded.

Werner Lemberg 9079c5d91a Provide C++ versions for public macros with casts.
Many FreeType clients use C++.  However `g++ -Wold-style-cast` warns for
macros with C-style casts even for system header files; this also affects
directories included with `-isystem`.  While this could be seen as a problem
with g++, the problem is more a philosophical one: Over the time, C and C++
diverged more and more, and some features of C are no longer the 'right'
solution in C++.

* include/freetype/config/public-macros.h (FT_STATIC_CAST,
FT_REINTERPRET_CAST): New macros.

* include/freetype/freetype.h (FT_ENC_TAG, FT_LOAD_TARGET_,

Werner Lemberg 93e6b3e8e9 [truetype] Updates for the forthcoming OpenType 1.9 standard (1/2).
This is in preparation for implementing `DeltaSetIndexMap` format 1, which
is used by `COLR` v1 tables, and which allows 32bit indices.

Alexei Podtelezhnikov 05089e8a07 [build/windows] Remove logging from default debug configurations.
DLG is rather costly for performance and should be used judiciously.
This removes it from the default configurations but gives an example
how to enable it using the `UserDefines` property.

Werner Lemberg 7ef266045f [sfnt] Reduce footprint if WOFF and WOFF2 support is not needed.
Based on a patch from metarutaiga (MR !106).  The gist of this commit is
that it doesn't make sense to support WOFF without compression (which would
be only possible in WOFF 1.0 anyway).

* src/sfnt/sfobjs.c (sfnt_open_font): Guard WOFF code with
`FT_CONFIG_OPTION_USE_ZLIB` block.
Guard WOFF2 code with `FT_CONFIG_OPTION_USE_BROTLI` block.

* src/sfnt/sfwoff.c, src/sfnt/sfwoff.h: Guard files with
`FT_CONFIG_OPTION_USE_ZLIB` blocks, not parts of the code.

* src/sfnt/sfwoff2.c, src/sfnt/sfwoff2.h, src/sfnt/woff2tags.c,
src/sfnt/woff2tags.h: Guard files with `FT_CONFIG_OPTION_USE_BROTLI` blocks,
not parts of the code.

tt_check_trickyness_family, tt_synth_sfnt_checksum, tt_get_sfnt_checksum,

Alexei Podtelezhnikov 7f4b9bfbc9 [dlg] Define DLG_STATIC explicitly.
DLG_STATIC is intended to disable Windows DLL linking attributes.
It does not hurt to define it explicitly when we wrap DLG code.
This fixes tons of LNK4286 and C4273 warnings from MSVC if we
forget to define DLG_STATIC as a compiler option.

* builds/windows/vc2010/freetype.vcxproj: Remove DLG_STATIC option.
* src/dlg/dlgwrap.c [FT_DEBUG_LOGGING]: Define DLG_STATIC.
* include/freetype/internal/ftdebug.h [FT_DEBUG_LOGGING]: Ditto.

Alexei Podtelezhnikov c693377ed3 [dlg] Lighten up the inclusions.

Jany Belluz fc55291b1c [truetype] Fix handling of packed deltas in Variation Fonts.
* src/truetype/ttgxvar (ft_var_readpackeddeltas): Don't expect the number of
bytes used to encode the deltas to be higher than the number of encoded
values.  The specification allows a very compact encoding; for example, a
list of 200 zeros can be encoded with just a couple of bytes.

We now count the consumed bytes to make sure to not read more than expected.

Jany Belluz 9ed5332fe6 [truetype] Fix CVAR handling of tuples for all points.
* src/truetype/ttgxvar (tt_face_vary_cvt): Function
`ft_var_readpackedpoints`, when it returns `ALL_POINTS`, also sets
`point_count` to value 0.  However, the CVAR code was incorrectly expecting
that `point_count` would be set to match the length of the CVT table.
