PS Type 1 and CID-keyed PS font drivers; other tables (`ALMX',
|
||||
`BBOX', etc.) are not supported yet.
|
||||
|
||||
- A new interface to extract advance values of glyphs without
|
||||
loading their outlines has been added. The functions are called
|
||||
`FT_Get_Advance' and `FT_Get_Advances'; they are defined in file
|
||||
`ftadvanc.h' (to be accessed as FT_ADVANCES_H).
|
||||
|
||||
|
||||
III. MISCELLANEOUS
|
||||
|
||||
- FT_MulFix is now an inlined function; by default, assembler code
|
||||
is provided for x86 and ARM. See FT_CONFIG_OPTION_INLINE_MULFIX
|
||||
and FT_CONFIG_OPTION_NO_ASSEMBLER (in ftoption.h) for more.
