It gives the +reference document and whether it is supported in FreeType 2. + + + file type: + The only special case is `MAC'; on older Mac OS versions, a `file' + is stored as a data and a resource fork, this is, within two + separate data chunks. In all other cases, the font data is stored + in a single file. + + wrapper format: + The format used to represent the font data. In the table below it + is used only if the font format differs. Possible values are `SFNT' + (binary), `PS' (a text header, followed by binary or text data), and + `LZW' (compressed with either `gzip' or `compress'). + + font format: + How the font is to be accessed, possibly after converting the file + type and wrapper format into a generic form. Bitmap formats are + `BDF', `PCF', and one form of `WINFNT'; all others are vector + formats. + + font type: + Sub-formats of the font format. `SBIT' and `MACSBIT' are bitmap + formats, `MM' and `VAR' support optical axes. + + glyph access: + If not specified, the glyph access is `standard' to the font format. + Values are `CID' for CID-keyed fonts, `SYNTHETIC' for fonts which + are modified versions of other fonts by means of a transformation + matrix, `COLLECTION' for collecting multiple fonts (sharing most of + the data) into a single file, and `TYPE_0' for PS fonts which are to + be accessed in a tree-like structure. + + FreeType driver: + The module in the FreeType library which handles the specific font + format. A missing entry means that FreeType doesn't support the + font format (yet). + + +Please send additions and/or corrections to wl@gnu.org or to the +FreeType developer's list at freetype-devel@nongnu.org (for subscribers +only). If you can provide a font example for a format which isn't +supported yet please send a mail too. + + +file wrapper font font glyph FreeType reference +type format format type access driver documents +---------------------------------------------------------------------------- + +--- --- BDF --- --- bdf 5005.BDF_Spec.pdf, X11 + + +--- SFNT PS TYPE_1 --- --- Type 1 GX Font Format + (for the Mac) +MAC SFNT PS TYPE_1 --- --- Type 1 GX Font Format + (for the Mac) +--- SFNT PS TYPE_1 CID --- 5180.sfnt.pdf (for the Mac) +MAC SFNT PS TYPE_1 CID --- 5180.sfnt.pdf (for the Mac) +--- SFNT PS CFF --- cff OT spec, 5176.CFF.pdf + (`OTTO' format) +MAC SFNT PS CFF --- cff OT spec, 5176.CFF.pdf + (`OTTO' format) +--- SFNT PS CFF CID cff OT spec, 5176.CFF.pdf +MAC SFNT PS CFF CID cff OT spec, 5176.CFF.pdf +--- SFNT PS CFF SYNTHETIC --- OT spec, 5176.CFF.pdf +MAC SFNT PS CFF SYNTHETIC --- OT spec, 5176.CFF.pdf +--- SFNT TT SBIT --- sfnt XFree86 (bitmaps only; + with `head' table) +--- SFNT TT MACSBIT --- sfnt OT spec (for the Mac; + bitmaps only; `bhed' table) +MAC SFNT TT MACSBIT --- sfnt OT spec (for the Mac; + bitmaps only; `bhed' table) +--- SFNT TT --- --- truetype OT spec (`normal' TT font) +MAC SFNT TT --- --- truetype OT spec (`normal' TT font) +MAC SFNT TT VAR --- truetype GX spec (`?var' tables) +--- SFNT TT --- COLLECTION truetype OT spec (this can't be CFF) +MAC SFNT TT --- COLLECTION truetype OT spec (this can't be CFF) + + +--- --- PS TYPE_1 --- type1 T1_SPEC.pdf + (`normal' Type 1 font) +MAC --- PS TYPE_1 --- type1 T1_SPEC.pdf + (`normal' Type 1 font) +--- --- PS TYPE_1 CID cid PLRM.pdf (CID Font Type 0; + Type 9 font) +--- --- PS MM --- type1 5015.Type1_Supp.pdf + (Multiple Masters) +--- --- PS CFF --- cff 5176.CFF.pdf (`pure' CFF) +--- --- PS CFF CID cff 5176.CFF.pdf (`pure' CFF) +--- --- PS CFF SYNTHETIC --- 5176.CFF.pdf (`pure' CFF) +--- PS PS CFF --- --- PLRM.pdf (Type 2) [1] +--- PS PS CFF CID --- PLRM.pdf (Type 2) [1] +--- PS PS CFF SYNTHETIC --- PLRM.pdf (Type 2) [1] +--- --- PS --- TYPE_0 --- PLRM.pdf +--- --- PS TYPE_3 --- --- PLRM.pdf (never supported) +--- --- PS TYPE_3 CID --- PLRM.pdf (CID Font Type 1; + Type 10 font; never supported) +--- PS PS TYPE_14 --- --- PLRM.pdf (Chameleon font; + Type 14 font; never supported?) +--- --- PS TYPE_32 CID --- PLRM.pdf (CID Font Type 4; + Type 32 font; never supported?) +--- PS TT --- --- type42 5012.Type42_Spec.pdf + (Type 42 font) +--- PS TT --- CID --- PLRM.pdf (CID Font Type 2; + Type 11 font) + + +--- ? ?
