* src/smooth/ftgrays.c (gray_raster_render): Check `outline'
correctly.
2007-12-21 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
Improvement of POSIX resource-fork accessor to load unsorted
references in a resource. In HelveLTMM (resource-fork
PostScript Type1 font bundled to Mac OS X since 10.3.x),
the appearance order of PFB chunks is not sorted.
Sorting the chunks by reference IDs is required.
references in a resource. In HelveLTMM (resource-fork PostScript
Type1 font bundled with Mac OS X since 10.3.x), the appearance order
of PFB chunks is not sorted; sorting the chunks by reference IDs is
required.
* include/freetype/internal/ftrfork.h (FT_RFork_Ref):
New structure type to store a pair of reference ID and offset
to the chunk.
* include/freetype/internal/ftrfork.h (FT_RFork_Ref): New structure
type to store a pair of reference ID and offset to the chunk.
* src/base/ftrfork.c (ft_raccess_sort_ref_by_id):
New function to sort FT_RFork_Ref by their reference ID.
* src/base/ftrfork.c (ft_raccess_sort_ref_by_id): New function to
sort FT_RFork_Ref by their reference IDs.
(FT_Raccess_Get_DataOffsets): Returns an array of offsets
that is sorted by reference ID.
