Have you tried using the -limit option to give imagemagick more room to play? Snipped from the docs: -limit <type> <value> Area, Disk, File, Map, or Memory resource limit Alternatively, for images that big, you might get more mileage out of an alternative called VIPS, for which there is a front-end called nip2. http://www.vips.ecs.soton.ac.uk/index.php?title=VIPS (also available in Debian/Ubuntu repositories, and likely others too) It's a little tricky to get used to, but lets you define operations that are processed in chunks off the disk. It is designed to handle images larger than available memory. I find it invaluable for large panoramic photo work. - Roger -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
