Yes I view in 800x600x8bits mode, my videocard is a kind of S3Trio64 (Trio64V2). > So typing u is still embarrassingly slow > on < 8-bit images. I have exactly 8 bits per pixel. It is 'gs' output viewed by 'page', hope its depth is not less than 8 ? > So that's the cause; the only quick solution > at present is to view a higher-depth image. Unfortunately my videocard does not seem to work in 16 or more bpps, as 'supported hardware' reads. -- mwg@alkar.net
