There is a section in the book _Image Processing in IDL_
(provided as a PDF file in the IDL distribution), starting
on page 233 that describes how to do this in both direct
graphics and object graphics. I couldn't find a reference
to it in the index, so I finally had to flip though the
book until I found it. I remembered seeing it there. :-)
Cheers,
David
