- 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.
- Image saved in the native graphics format used by Silicon Graphics workstations; can store 8 to 32 bits per pixel; also supports Run-length encoding (RLE) compression for reducing the image file size.
