* src/truetype/ttgload.c (TT_Load_Glyph): Use the glyph's (scaled)
`linearHoriAdvance' if the sbit's `horiAdvance' value is zero.

Cf. font `Fixedsys Excelsior' v3.01 (FSEX300.ttf), glyph A, 16ppem.

Werner Lemberg 2ba871b289 * src/cache/ftcmanag.c (FTC_Manager_Reset): Add missing cache flush.
This code, present since eight(!) years in the unused `CACHE'
branch, has been forgotten to apply to the master branch.  It's
really amazing that noone has ever complained since
`FTC_Manager_Reset' is pretty useless without flushing the cache.

Werner Lemberg 4447b2c84e [cff] Add early exit feature for width-only calls.
This is for `FT_Get_Advance'.

There are 7 places where the spec says the width can be defined:

  hmoveto
  vmoveto
  rmoveto
  endchar

Werner Lemberg 8d8508e4d2 Missed some cppcheck items. 2013-06-04 13:09:01 +02:00
Werner Lemberg dc624ca4dc Apply fixes for cppcheck nitpicks.
http://cppcheck.sourceforge.net/

Note that the current version heavily chokes on FreeType, delivering
even wrong results.  I will report those issues to the cppcheck team
so that a newer version gives improved results hopefully.

*/* Improve variable scopes.
*/* Remove redundant initializations which get overwritten.

* src/base/ftmac.c ,builds/mac/ftmac.c (count_faces_scalable):
Remove unused variable.

* src/base/ftdbgmem.c (ft_mem_table_destroy): `table' can't be zero.

* src/gxvalid/gxvkern.c (gxv_kern_subtable_fmt1_entry_validate):
Remove functionless code.

* src/tools/ftrandom.c (main): Fix memory leak.

Werner Lemberg 2429dc3d7c Add CFF_CONFIG_OPTION_OLD_ENGINE configuration option.
This controls whether the old FreeType CFF engine gets compiled into
FreeType.  It is now disabled by default.

* devel/ftoption.h, include/freetype/config/ftoption.h
(CFF_CONFIG_OPTION_OLD_ENGINE): New macro.

* src/cff/cffdrivr.c (cff_property_set), src/cff/cffgload.c

src/cff/cffgload.h, src/cff/cffobjs.c (cff_driver_init): Use
CFF_CONFIG_OPTION_OLD_ENGINE to guard the affected code.

2013-06-02 23:38:13 +02:00
Behdad Esfahbod 760d342d37 Add support for color embedded bitmaps (eg. color emoji).
A new load flag, FT_LOAD_COLOR, makes FreeType load color
embedded-bitmaps, following this draft specification

  https://color-emoji.googlecode.com/git/specification/v1.html

which defines two new SFNT tables, `CBDT' and `CBLC' (named and
modeled after `EBDT' and `EBLC', respectively).  The color bitmaps
are stored in the new FT_PIXEL_MODE_BGRA format to represent BGRA
pre-multiplied sRGB images.  If PNG support is available, PNG color
images as defined in the same proposed specification are supported
also.

Note that color bitmaps are converted to grayscale if client didn't
ask for color.

Add `--without-png' option.

Werner Lemberg 77c39b1deb [cff] Make Adobe CFF engine work correctly on 64bit hosts.
Reported by numerous people on the `freetype-devel' list.  Without
this fix, glyphs aren't properly aligned on a common baseline.

On 64bit systems, `FT_Pos' expands to `long int', having a width of
64bit.  `CF2_Fixed' expands to `int' which is normally 32bit wide on
64bit hosts also.  Wrong casts filled up the blues arrays with
incorrect values.  Note that all blues values are accessed with the
`cf2_blueToFixed' macro which handles the 64bit to 32bit conversion.

* src/cff/cf2ft.h (cf2_getBlueValues, cf2_getOtherBlues,
cf2_getFamilyBlues, cf2_getFamilyOtherBlues): Use `FT_Pos' for
`data', not `CF2_Fixed'.
