* [psaux] (1/2) Handle fonts that use SEAC for ligatures (#56580).Chris Liddell2019-07-042-6/+37
| | | | | | | | | | | | | | | | | | | As originally intended, a Type 1 SEAC charstring would be used for an accented glyph (like `acaron' or `uumlaut'), where the advance width of the SEAC glyph is the same as that of the `base' glyph (like `a' or `u'). In this case it is not uncommon for the SEAC glyph to not use an (H)SBW opcode of its own but to rely on the value from the base glyph. However, out-of-spec fonts also use SEAC glyphs for ligatures (like `oe' or `fi'), and in those cases the overall advance width is greater than that of the `base' glyph. For this reason we have to allow that the SEAC glyph can have an (H)SBW value of its own, and if it has, retain this value, rather than the one from the base glyph. * src/psaux/psintrp.c (cf2_interpT2CharString) <cf2_escSEAC>: Implement it.

* [smooth] Restore the span buffering for direct mode only.Alexei Podtelezhnikov2019-06-132-6/+39
| | | | | | | | | | | | The buffer size FT_MAX_GRAY_SPANS is set to 10 spans, which should be enough to cover the entire scanline for simple glyphs in most cases: each slightly slanted edge needs up to two spans, plus a filling span in-between. This is not new, we used to do it before cb4388783cecc. * src/smooth/ftgrays.c (gray_TWorker): Add `spans' and `num_spans'. (gray_hline, gray_sweep): Implement the span buffering. (gray_raster_render): Use negative `num_spans' to avoid the direct mode.
* * include/freetype/ftmodapi.h (FT_DebugHook_Func): Return error.Alexei Podtelezhnikov2019-06-122-1/+8

| | | | | | | | | | Instead of an intentionally missing `break' statement there must be a comment line containing `fall through' (and nothing else) right before the next `case' statement.

* [truetype] Actually scale varied CVT values.Werner Lemberg2019-05-163-0/+40
| | | | | | | | | Up to now, only the unscaled CVT values were varied; in other words, the `CVAR' data was never used for bytecode hinting. * src/truetype/ttgxvar.c (tt_cvt_ready_iterator): New auxiliary function. (tt_face_vary_cvt): Use it to trigger rescaling of CVT values.
* [truetype] Use 26.6 format for storing unscaled CVT values.Werner Lemberg2019-05-165-14/+40
| | | | | | | | | | | | | | | | | If `CVAR' data is applied to variation fonts, fractional values are possible. * include/freetype/internal/tttypes.h (TT_FaceRec): Change type of `cvt' from `FT_Short' to `FT_Int32'. * src/truetype/ttgxvar.c (FT_fdot6ToFixed): New macro. (tt_face_vary_cvt): Use it to update code to 26.6 format. * src/truetype/ttobjs.c (tt_size_run_prep): Update code to 26.6 format. * src/truetype/ttpload.c (tt_face_load_cvt): Stora data in 26.6 format.
* * src/truetype/ttgload.c (load_truetype_glyph): Init `unrounded'.Werner Lemberg2019-05-162-1/+8

* [truetype] Doh. Fix last commit to make it work.Werner Lemberg2019-05-133-29/+94
| | | | | | | | | | | | | | | | | | | | | | | | Very embarassing :-) Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=14701 https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=14705 https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=14710 * src/truetype/ttgload.c (IS_DEFAULT_INSTANCE): Move up and add argument; update all callers. (TT_Process_Simple_Glyph): Use it. The `unrounded' array is active for variation fonts only, thus also enclose related code with `#ifdef TT_CONFIG_OPTION_GX_VAR_SUPPORT ... #endif' where necessary. Revert commit a113e5d from 2019-05-09, and don't use `extra_points2' but allocate a temporary array. Speed up the scaling of the `unrounded' array. * src/truetype/ttgxvar.c (FT_fixedToInt, FT_FixedToFdot6): Fix type conversions and rounding. The unsigned type must have more or equal bits to the signed type.
* [truetype] Increase precision of font variation (#54371).Werner Lemberg2019-05-115-24/+89
| | | | | | | | | | | | | | | | This patch make FreeType use font units in 26.6 format internally instead of integers. * src/truetype/ttgxvar.c (FT_fixedToFdot6): New macro. (TT_Vary_Apply_Glyph_Deltas): Add argument to output unrounded font coordinates. * src/truetype/ttgxvar.h: Updated. * src/truetype/ttgload.c (TT_Process_Simple_Glyph): Use `extra_points2' array to temporarily hold unrounded point coordinates; use them to compute scaled coordinates and linear advance width and height. (load_truetype_code): Adjust similarly.
* * src/truetype/ttgload.c (TT_Process_Simple_Glyph): Minor.Werner Lemberg2019-05-092-8/+9
