I would like to be able to read and write jpeg2000 images with IDL. Are
there
any libraries available for this purpose.
Regards,
Phil

1. Read your JPEG file and the image.
2. Code your coordinate information up in XML format.
3. Write your JPEG2000 file, adding the coordinate information
via an XML box (use the XML keyword and set the JP2 keyword
to 1).
4. Give your JPEG2000 file a "jp2" file extension.
As far as how to do step 2 goes, IDL leaves you pretty much
on your own. The Digital Imaging Group's DIG35 Initiative
looks like a likely place to find an XML example:

I poked around a little bit this morning, but didn't find
exactly what I was looking for. If you find a good example,
please report back to us. :-)
This paper might provide some clues:
