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.
This is a format for storing and presenting text information. It’s also referred to as CID 2 and is basically used for imaging and creating complex fonts in PDF. It’s based on the TrueType system, but allows for more precise adjustment and allows for refined writing due to a 16-bit structure that is very important when displaying Asian language symbols.
