I'm guessing that one of the netpbm tools will handle transparency,
it's just a matter of figuring out which one. Didn't this come up on
a recent thread? I seem to remember trying it out on something and
getting a transparent background. When I get some time later I'll
look into it. It would be simple enough to add a prompt asking if
you'd like a transparent background, I guess.
Now that you mention it that rings a bell with me too! I'll have to
search---
giftoppm foobar.gif | ppmtogif -transparent '#rgb' > fooquux.gif
works if you want gif. First translate to ppm, then translate back to
gif with the -transparent flag specifying which color, (in this case
#fff) will be transparent.
pnmtopng has the transparent argument, but pnmtotiff and jpeg don't
since they don't support transparency...so, using your script, if you
want transparency, you have to choose png for the output, then on the
translation step from ppm just add the appropriate flags. I just tried
it adding a quick -transparent '#ffffff' to the command line and then
selecting png so it would work. It worked like a charm:)

Re: the footers: are you talking about the "engraving by Lilypond"
footer or some other thing?
Yep. Or the copyright statement, or the typesetter statement, et.al.
