|

|
|
* @Description:
|
|
* A structure used to store TrueType/sfnt specific cmap information
|
|
* which is not covered by the generic @FT_CharMap structure. This
|
|
* structure can be accessed with the @FT_Get_TT_CMap_Info function.
|
|
*
|
|
* @Fields:
|
|
* language ::
|
|
* The language ID used in Mac fonts. Definitions of values are in
|
|
* `ttnameid.h'.
|
|
*
|
|
* format ::
|
|
* The cmap format. OpenType 1.6 defines the formats 0 (byte
|
|
* encoding table), 2~(high-byte mapping through table), 4~(segment
|
|
* mapping to delta values), 6~(trimmed table mapping), 8~(mixed
|
|
* 16-bit and 32-bit coverage), 10~(trimmed array), 12~(segmented
|
|
* coverage), 13~(last resort font), and 14 (Unicode Variation
|
|
* Sequences).
