`tttables.h') is available to get the language ID of a
TrueType/SFNT cmap.
- The cache sub-system has been rewritten.
- There is now support for deinstallation of faces.
- A new API function `FTC_Manager_RemoveFaceID' has been added
to delete all `idle' nodes that correspond to a given
FTC_FaceID. All `locked' nodes (i.e., those with a reference
count > 0), will be modified to prevent them from appearing in
further lookups (they will be cleaned normally when their
reference count reaches 0).
- There is now support for point scaling (i.e., providing
character sizes in points + dpis, instead of pixels).
- Three abstract cache classes are now available:
FTC_GCache: Used to store one glyph item per cache node,
with the ability to group common attributes into
`families'. This replaces the old
FTC_GlyphCache class.
FTC_ICache: Used to store one FT_Glyph per cache node. This
extends FTC_GCache. Family definition, family
comparison, and glyph loading are however left
to sub-classes.
FTC_SCache: Used to store up to 16 small bitmaps per cache
node. This extends FTC_GCache. Family
definition, family comparison and glyph loading
are however left to sub-classes.
- The file `src/cache/ftcbasic.c' implements:
FTC_ImageCache: Extends FTC_ICache; implements family
definitions and glyph loading similar to the
old API.
FTC_SBitCache: Extends FTC_SCache, implements family
definitions and glyph loading similar to the
old API
Client applications should be able to extend FTC_GCache,
FTC_ICache, or FTC_SCache much more easily (i.e., less code to
write, and less callbacks). For example, one could envision
caches that are capable of storing transformed (obliqued),
stroked, emboldened, or colored glyph images. Use
`ftcbasic.c' as an example.
- All public APIs are now in `include/freetype/ftcache.h', (to
be accessed as `FT_CACHE_H'). The contents of
`include/freetype/cache/' is only needed by applications that
wish to implement their own caches.
- There were some major performance improvements through the use
of various programming tricks. Cache hits are up to 70%
faster than in the old code.
- The FTC_CMapCache has been simplied. Charmaps can only be
accessed by index right now. There is also a new API named
`FT_Charmap_GetIndex' for this purpose.
- The demo programs have been updated to the new code. The
previous versions will not work with the current one.
