TTF2MF obtains information on True Type fonts by using Windows GDI functions (GetGlyphOutLine etc.). That is why the program works with installed fonts instead of .ttf files. The conversion by TTF2MF does not take into account the so-called hinting which is an important property of True Type fonts. For more information on True Type format and True Type tools look at http://www.truetype.demon.co.uk http://www.freetype.org The sources of the program are free available on quest.
