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).
