Originally reported by: hideyuki@users.sourceforge.net Entire TrueType outline data in CIDFontType 2 and TrueType fonts are loaded into memory at once. Incremental loading of the outline data is indispensable for practical use of Asian fonts.
Comment originally by lpd@users.sourceforge.net I suggest that anyone who would like to work on this project start by looking at how CIDFontType 0 fonts do incremental loading (lib/gs_cidfn.ps and src/zfcid0.c). I suspect that much of this code can be also be used with CIDFontType 2 and TrueType fonts.
Comment originally by lpd@users.sourceforge.net There is one other type of CID-keyed font that should also be loaded incrementally: CFF CIDFontType0, i.e., a CIDFontType 0 font represented using the compact binary CFF format. This is important because this is one of the two variants of Asian OpenType fonts (the other is essentially the same as TrueType). Ghostscript already supports both of these OpenType variants, but not with incremental loading.
