This library can be used to:
- Read TrueType, OpenType (with TrueType glyphs), WOFF font files
- Extract basic info (name, style, etc)
- Extract advanced info (horizontal metrics, glyph names, glyph shapes, etc)
- Make an Adobe Font Metrics (AFM) file from a font

TTF2PT1 is a modification of Andrew Weeks TTF2PFA True Type to Postscript Type 3 converter. Which will convert Most True Type Fonts to an Adobe Type 1 .pfa file. And also the other font formats supported by the FreeType library to an Adobe Type 1 .pfa file. And the BDF fonts to an Adobe Type 1 .pfa file. Yet another use is as a hinting engine: feed it an unhinted or poorly hinted Adobe Type 1 font through the FreeType library and get it back with freshly generated hints. If you want .pfb files, don't despair: they can be produced too. The files produced by default are in human readable form, which further needs to be encoded with the t1utilities, to work with most software requiring type 1 fonts. But for the lazy people ttf2pt1 includes a built-in portion of t1utilities as well.

TTF Parser can load TrueType fonts, display glyphs and dump out glyph data to XML files.

fontcrunch is a program that optimizes TrueType font splines - a "simplify" command. It tries to create a visual match for the spline using the smallest number of TrueType points. It is notable for counting on-curve points interpolated between two off-curve points as "free," making useful filesize savings.
