- 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.
- FTS file format is used to edit, store and transmit images with metadata (data with spatial and photometric calibrations) for scientific purposes. Most times it stores the data without the actual associated images.
