1 This file contains a list of various font formats. It gives the
2 reference document and whether it is supported in FreeType 2.
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.
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').
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.
23 font type:
24 Sub-formats of the font format. `SBIT' and `MACSBIT' are bitmap
25 formats, `MM' and `VAR' support optical axes.
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.
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.

127 [1] Support should be rather simple since this is identical to `CFF' but
128 in a PS wrapper.
130 [2] Official PFR specification:

133 http://www.bitstream.com/categories/developer/truedoc/pfrspec1.2.pdf
135 The syntax of the auxiliary data is not defined there, but is
136 partially defined in MHP 1.0.3 (also called ETSI TS 101812 V1.3.1)
137 section 7.4.

142 (free registration required).
144 [3] Support is rudimentary currently; some tables are not loaded yet.
146 [4] There is no formal PCF specification; you have to deduce the exact
147 format from the source code within X11. George Williams did this for
148 his FontForge editor:
