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.)
