[edit] Features
Fontforge supports several font formats like TrueType, PostScript, OpenType, CID-keyed, multi-master, CFF, SVG, BDF, Datafork TrueType, etc. Fontforge can convert fonts from one format to another. FontForge can also store fonts in its native format called "spline font database files" using the .sfd extension, which has the advantage that is text-based.[3] This format facilitates designer collaboration because it allows diffs to be easily created and reviewed; the two users usually need to use the same Fontforge version, otherwise the .sfd text representation can differ too much to be useful for different reviewing.
To facilitate automated format conversions and other transformations, Fontforge implements two scripting languages: its own legacy language, and more recently Python.[4] Support for one or both scripting languages can be selected at compile time. FontForge can be built as a python module to be loaded from python scripts.[5]
Fontforge supports Adobe's OpenType feature file specification (with its own extensions to the syntax).[6] It also supports the unofficial Microsoft mathematical typesetting extensions (MATH table)[7] introduced for Cambria Math and supported by Office 2007 and XeTeX. At least one free OpenType mathematical font has been developed in FontForge (see below).
FontForge uses FreeType for rendering fonts on screen.[8] Since the 15-Nov-2008 release, FontForge can use libcairo and libpango for graphics and text rendering[9] providing anti-aliased graphics and complex text layout support.
FontForge can use Potrace or AutoTrace to auto trace bitmap images and import them into a font.
Parts of FontForge code are used by the LuaTeX typesetting engine for reading and parsing OpenType fonts.[10]
