Armin Hasitzka 6986ddac1e [cff] Fix boundary checks.
642bc7590c introduced dynamically
allocated memory when parsing CFF files with the "old" engine.  Bounds
checks have never been updated, however, leading to pointless
comparisons of pointers in some cases.  This commit presents a
solution for bounds checks in the CFF module with an extended logic
for the "old" engine while staying as concise as possible for the
"new" one.

* src/cff/cffparse.h: Introduce the struct `CFF_T2_StringRec' and
the additional field `t2_strings' within `CFF_ParserRec'.

* src/cff/cffparse.c (cff_parser_within_limits): Move all boundary
checks into this new function and update the rest of `cffparse.c' to
use it.

Sebastian Rasmussen 6a4718a3a0 Fix use of uninitialized memory.
* src/psaux/psintrp.c (cf2_interpT2CharString): The call to
`cf2_arrstack_setCount' may fail because the allocator ran out of
memory.  When this happens the stack is still written to before the
error condition is checked.  This means that FreeType writes outside
of allocated memory.  This commit moves the error check prior to the
stack assignment, hence the function now properly returns with an
error condition.

Werner Lemberg b66d6a9112 CHANGES: Document recent metrics change from Nikolaus. 2019-02-06 07:38:25 +01:00
Nikolaus Waxweiler a6feefdfef [truetype] Apply MVAR hasc, hdsc and hlgp metrics to current FT_Face metrics.
Instead of setting typo or win metrics as the new FT_Face metrics
indiscriminately, apply only typo deltas to the currently active FT_Face
metrics. This prevents line height differences when e.g. the default
outlines were used as the regular face and instances for everything else.

* src/truetype/ttgxvar.c (tt_apply_mvar): Implement.
2019-02-02 15:50:57 +00:00
Nikolaus Waxweiler f72b00746c [sfnt] Use typo metrics if OS/2 fsSelection USE_TYPO_METRICS bit is set.
If the OS/2 table exists and fsSelection bit 7 (USE_TYPO_METRICS) is set,
use the sTypo* set of values to compute the FT_Face's ascender, descender
and height. Otherwise, fall back to old behavior.

* src/sfnt/sfobjs.c (sfnt_load_face): Implement.

Chris Liddell b75abeb5e6 [psaux] Fix closepath (#55414).
All of the Type 1 path building is done with code common to the
revised CFF engine, with the exception of closepath, which was still
calling ps_builder_close_contour(), thus previously cached segments
were not always written to the path, and glyph corruption, or even
invalid outlines were possible.

* src/psauc/psinterp.c (cf2_interpT2CharString) <cf2_cmdCLOSEPATH>:
Switch to calling `cf2_glyphpath_closeOpenPath'.
