- 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.
- An RGBA file is a color bitmap image format created by Silicon Graphics (SGI). It is similar to the .RGB file as it supports color RGB channels with an alpha channel.
