- Description
- SFD (Spline Font Database) is the native, text-based source format of the FontForge font editor. It stores a font's glyph outlines, metrics, kerning, OpenType tables and editing state, so a font can be reopened and edited losslessly and then exported to TrueType, OpenType, WOFF or Type 1.
- Standard font format used by Mac OS X; font contents are stored in the data fork part of the file instead of the resource fork (which was used by fonts in Mac OS Classic).
