suzuki toshiya 58cb359335 [truetype] Recalculate the sfnt table checksum always. 
* src/truetype/ttobjs.c (tt_get_sfnt_checksum): Recalculate
the sfnt table checksum even if non-zero value is writte in
the TrueType font header.  Some bad PDF generators write
wrong values.  For detail, see examples and benchmark tests
of the latency by recalculation:

suzuki toshiya 1e89d15a27 [truetype] Register a set of tricky fonts, NEC FA family. 
* src/truetype/ttobjs.c (tt_check_trickyness_sfnt_ids):
Add 8 checksum sets for NEC FA family.  For the tricky fonts
without some tables (e.g. NEC FA fonts lack cvt table),
extra check is added to assure that 0-length table in the
registry is not included in the font.

suzuki toshiya 89208861ef [truetype] Fix a bug in the sfnt table checksum getter. 
* src/truetype/ttobjs.c (tt_get_sfnt_checksum): Check the
return value of face->goto_table() correctly.

Werner Lemberg b9aa1f1339 [autofit] Improve tracing messages.

suzuki toshiya 86b7b2f614 [truetype] Revert the reordering of trickyness checking. 
Trickyness check by the family name is faster than that by
the checksum.
 2011-04-26 03:46:12 +09:00
suzuki toshiya abc47aa136 [truetype] Always check the checksum to identify tricky fonts. 
Some PDF generators mangle the family name badly, prioritize
the check by the sfnt table checksums than the check by the
family name.  For sample PDF, see
http://lists.gnu.org/archive/html/freetype-devel/2011-04/msg00073.html

* src/truetype/ttobjs.c (tt_check_trickyness): Exchange the order
of tt_check_trickyness_family() and tt_check_trickyness_sfnt_ids().

suzuki toshiya 233f9d5dd2 [autofit] Add more Indic scripts with hanging baseline. 
* src/autofit/afindic.c (af_indic_uniranges): Tibetan, Limbu,
Sundanese, Meetei Mayak, Syloti Nagri and Sharada scripts are
added.

Behdad Esfahbod 8c82ec5b17 Always ignore global advance. 
This makes FT_LOAD_IGNORE_GLOBAL_ADVANCE_WIDTH redundant,
deprecated, and ignored.  The new behavior is what every major user
of FreeType has been requesting.  Global advance is broken in many
CJK fonts.  Just ignoring it by default makes most sense.

* src/truetype/ttdriver.c (tt_get_advances),
src/truetype/ttgload.c (TT_Get_HMetrics, TT_Get_VMetrics,
tt_get_metrics, compute_glyph_metrics, TT_Load_Glyph),
src/truetype/ttgload.h: Implement it.

* docs/CHANGES: Updated.

Kan-Ru Chen 21b1a0de7c Fix reading of signed integers from files on 64bit platforms. 
Previously, signed integers were converted to unsigned integers, but
this can fail because of sign extension.  For example, 0xa344a1eb
becomes 0xffffffffa344a1eb.

We now do the reverse which is always correct because the integer
size is the same during the cast from unsigned to signed.

* include/freetype/internal/ftstream.h, src/base/ftstream.c
(FT_Stream_Get*): Replace with...
(FT_Stream_GetU*): Functions which read unsigned integers.
Update all macros accordingly.
