1 This file contains a list of various font formats. It gives the
2 reference document and whether it is supported in FreeType 2.
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
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), and
15 `LZW' (compressed with either `gzip' or `compress').
18 How the font is to be accessed, possibly after converting the file
19 type and wrapper format into a generic form. Bitmap formats are
20 `BDF', `PCF', and one form of `WINFNT'; all others are vector
24 Sub-formats of the font format. `SBIT' and `MACSBIT' are bitmap
25 formats, `MM' and `VAR' support optical axes.
28 If not specified, the glyph access is `standard' to the font format.
29 Values are `CID' for CID-keyed fonts, `SYNTHETIC' for fonts which
30 are modified versions of other fonts by means of a transformation
31 matrix, `COLLECTION' for collecting multiple fonts (sharing most of
32 the data) into a single file, and `TYPE_0' for PS fonts which are to
33 be accessed in a tree-like structure.
