dvi2bitmap is a utility to convert TeX DVI files directly to bitmaps,
without going through the complicated (and slow!) route of conversion
via PostScript and PNM. The prime motivation for this is to prepare
mathematical equations for inclusion in HTML files, but there are
plenty of uses beyond that. It uses the same kpathsea font-searching
library as other TeX programs, again as long as you have the
appropriate library installed.
