Hi Thomas, sometime early next year we plan to come with a first release of an image processing package for ROOT. This will solve all these problems. The package is currently being developed by Reiner Rohlfs (Reiner.Rohlfs@obs.unige.ch) based on requirements of the astronomy community. Concerning your X11 error you can use xmon (http://www.faqs.org/faqs/motif-faq/part9/section-41.html) to analyze which X message causes the error and send me the trace or send me a small program demonstrating the problem.
