oops. that gets x and y but dims isn't the right format for the -g arg.

Thanks for trying. I'll check back to see if you solve the problem,
but, like I said, please don't try too hard. I imagine imagemagick
or gimp or similar tool could do the job if I really needed it done.
(One or the other of Mr.Duck or Mr.Rabbit is, however, quite depressed
by the failure, though I can't quite tell which one.)

I semi-solved the problem, or, rather, side-stepped it.
I just ran  xv duckrabbit.jpg  and immediately used xv to save
it as "full color". Then ran meme.sh against that, and it worked
out fine. Could you maybe easily check in meme.sh whether or not
you're given a color image to begin with, and add in a similar
step if needed?

That could work. What I was thinking was to side-step
by converting first, then getting the dims from the eps,
whatever the resulting size ended up being.
