As a Digest reader, I see that your question has been ably answered by the usual suspects… I just wanted to add that I have an app where a user is allowed to extract a rectangular area from a larger image, with the added twist that the original image may be too large to display, so that the extraction (a kind of cookie-cutter approach) is done on the scaled-down image, but what gets saved is the corresponding extract from the unscaled image, if you see what I mean. Turns out it can all be done fairly neatly in LC. If this is of interest I can explain more - if not, not much bandwidth lost.
