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 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.
