Christian,
Thanks for your reply. One would certainly expect such a routine to be
present in the astronomy library, and in fact it's the first place I
looked. It's quite surprising, but, unfortunately, I found no such
routines here. Perhaps you can point out a specific routine that I have
overlooked. Otherwise, my search continues.
Thanks also for your other two indications. I will look into them.

You might have a look at the IDL astronomy library if there is something
like that already there at
http://idlastro.gsfc.nasa.gov/homepage.html

A seedfill routine and maybe other graphics related stuff is contained in
the JHU/APL/S1R IDL Library. See ftp://fermi.jhuapl.edu/www/s1r/idl/idl.html.

You can read and write JPEGs using idl procs read_jpeg and write_jpeg. See
user guide chapter 16 (Image Display Routines) how to display them on your
graphics device once they are read into idl arrays.

Christian
