| 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. |

| in a PS wrapper. |
