12:54:57beachI am attempting to write a McCLIM application for manipulating large-ish gray-level images. Currently 2500x3500 pixels, but I would like to do 5000x7000 at some point. I used the technique jackdaniel told me about to turn the PGM into a pattern and that works fine. Displaying the image takes only a few seconds. However scrolling is unbearably slow. Each small amount requires the entire visible area to be cleared and redrawn.
12:55:23beachIs there a better way to do this with, say, pixmaps, so that scrolling will be tolerable?
