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), and `LZW' (compressed with either `gzip' or `compress').
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 devel@freetype (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.
