t1infos – Utilities for PostScript fonts

There are here two little programs written in C (using t1lib) for scanning Type 1 fonts, and doing:

• compute the black area of each glyph, with how much percent of the square containing the glyph is black, and
• checking if the extremas (see Adobe Type 1 specifications) of the outline are correct, and tell which one are missing.

There is also here a PostScript dictionary containing three algorithms for automatic kerning (the kerning is computed on the fly instead of being pre-computed by external software like TeX, groff or lout; very useful for some PostScript hacking). Two of these algorithms are quite classical; the third is original and is PostScript-optimized. The PostScript file in the distribution contains both demonstration code and the dictionary itself.
