Ara, I received your email at my home address but my reply to your .gov address bounced(?). Anyway, the ImageMagick developers say that convert -quality 100 image.tif image.jp2 should do the trick. I see that you've already tried that with GraphicsMagick, though. The two packages are not entirely identical, so maybe it will work with ImageMagick. If it doesn't work then probably you'll get faster & better answers by posting directly to the magick-users@imagemagick.org mailing list. This is one you have to join before you can post. The instructions are on the ImageMagick web site. If you can get the convert command to work but the conversion doesn't work with RMagick give me a shout and I'll investigate. Please let me know if there's anything else I can do to help!
