[texhax] Extract equations as EPS from larger doc?

[Steve Schwartz]

I had some reason to look into similar things some years back. My own
notes provide the following summary of what I found, though I'll confess
that I forget exactly how any of them work. Most are geared toward
bitmap output, but perhaps not all.

PS As an alternative for something with vector capabilities, I think I'd
be inclined to put the equations on separate plain (pagestyle{empty})
pages, use pdflatex to generate a pdf, then run the result through
pdfcrop to trim all the white space. Finally something from the
pdftoolkit pdftk will split the resulting multi-page pdf into separate
pages, meaning separate pdf's for each equation.

=================================
There are a variety of things that will take in latex and spit out
images (gifs or pngs) that I've discovered. They include:

latex2png (part of latex2rtf)
mimetex
gladtex (which includes a commandline eqn2gif or somesuch)
latexrender
tex2gif
