This file contains a list of various font formats. 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), | |
`LZW' (compressed with either `gzip' or `compress'), and | |
`BZ2' (compressed with `bzip2`). | |
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. | |

[1] Support should be rather simple since this is identical to `CFF' but | |
in a PS wrapper. | |
[2] Official PFR specification: | |
http://www.bitstream.com/categories/developer/truedoc/pfrspec.html | |
http://www.bitstream.com/categories/developer/truedoc/pfrspec1.2.pdf | |
The syntax of the auxiliary data is not defined there, but is | |
partially defined in MHP 1.0.3 (also called ETSI TS 101812 V1.3.1) | |
section 7.4. | |

THE X WINDOW SYSTEM SERVER: X VERSION 11, RELEASE 5 | |
Elias Israel, Erik Fortune, Digital Press, 1992 | |
ISBN 1-55558-096-3 | |
for a specification given in Appendix D on pgs. 436-450. However, | |
this information might be out of date; unfortunately, there is no | |
PCF specification available online, and this book is out of print. | |
George Williams deduced the font format from the X11 sources and | |
documented it for his FontForge font editor: | |
