+ − 1 This file contains a list of various font formats. It gives the
+ − 2 reference document and whether it is supported in FreeType 2.
+ − 3
+ − 4
+ − 5 file type:
+ − 6 The only special case is `MAC'; on older Mac OS versions, a `file'
+ − 7 is stored as a data and a resource fork, this is, within two
+ − 8 separate data chunks. In all other cases, the font data is stored
+ − 9 in a single file.
+ − 10
+ − 11 wrapper format:
+ − 12 The format used to represent the font data. In the table below it
+ − 13 is used only if the font format differs. Possible values are `SFNT'
+ − 14 (binary), `PS' (a text header, followed by binary or text data),
+ − 15 `LZW' (compressed with either `gzip' or `compress'), and
+ − 16 `BZ2' (compressed with `bzip2`).
+ − 17
+ − 18 font format:
+ − 19 How the font is to be accessed, possibly after converting the file
+ − 20 type and wrapper format into a generic form. Bitmap formats are
+ − 21 `BDF', `PCF', and one form of `WINFNT'; all others are vector
+ − 22 formats.
+ − 23
+ − 24 font type:
+ − 25 Sub-formats of the font format. `SBIT' and `MACSBIT' are bitmap
+ − 26 formats, `MM' and `VAR' support optical axes.
+ − 27
+ − 28 glyph access:
+ − 29 If not specified, the glyph access is `standard' to the font format.
+ − 30 Values are `CID' for CID-keyed fonts, `SYNTHETIC' for fonts which
+ − 31 are modified versions of other fonts by means of a transformation
+ − 32 matrix, `COLLECTION' for collecting multiple fonts (sharing most of
+ − 33 the data) into a single file, and `TYPE_0' for PS fonts which are to
+ − 34 be accessed in a tree-like structure.
+ − 35
+ − 36 FreeType driver:
+ − 37 The module in the FreeType library which handles the specific font
+ − 38 format. A missing entry means that FreeType doesn't support the
+ − 39 font format (yet).
+ − 40
+ − 41
+ − 42 Please send additions and/or corrections to wl@gnu.org or to the
+ − 43 FreeType developer's list at freetype-devel@nongnu.org (for subscribers
+ − 44 only). If you can provide a font example for a format which isn't
+ − 45 supported yet please send a mail too.
