However, the SANE API allows a frontend to request a specific read size. Yes, it's called a maximum buffer size, but the implication is that that is the optimum size transfer for the frontend. A properly written backend should attempt to honor that request and not respond with less without a good reason. -- Dave Close Dreamworks SKG, Animation Technology +1 818 695 6962 Glendale California 91201-3007 dcl...@anim.dreamworks.com http://www.dreamworks.com/
