"SfR Fresh" - the SfR Freeware/Shareware Archive 
Member "freetype-2.3.7/docs/formats.txt" of archive freetype-2.3.7.tar.gz:
As a special service "SfR Fresh" has tried to format the requested source page into HTML format using source code syntax highlighting with prefixed line numbers.
Alternatively you can here view or download the uninterpreted source code file.
That can be also achieved for any archive member file by clicking within an archive contents listing on the first character of the file(path) respectively on the according byte size field.
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), and
15 `LZW' (compressed with either `gzip' or `compress').
16
17 font format:
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
21 formats.
22
23 font type:
24 Sub-formats of the font format. `SBIT' and `MACSBIT' are bitmap
25 formats, `MM' and `VAR' support optical axes.
26
27 glyph access:
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.
34
35 FreeType driver:
36 The module in the FreeType library which handles the specific font
37 format. A missing entry means that FreeType doesn't support the
38 font format (yet).

41 Please send additions and/or corrections to wl@gnu.org or to the
42 FreeType developer's list at freetype-devel@nongnu.org (for subscribers
43 only). If you can provide a font example for a format which isn't
44 supported yet please send a mail too.

125 [1] Support should be rather simple since this is identical to `CFF' but
126 in a PS wrapper.
