- 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.
- JBIG is a lossless compression file format that was created for the fax machine; it can be used by other image file formats. The files created by JBIG format are smaller compared to G3 and G4 file formats.
