Thanks Jim, but using canvas size presupposes that I know beforehand what position and size (in pixels or linear measure + resolution) the cropped image is going to be as well as the aspect ratio of the 2 sides. I often have to selectively enlarge 6 by 4 photos to fill an A4 sheet (printable area 1.371:1 on my printer). Using the selection marquee on C.A.R. allows me to choose the best crop position and still know that the image is the right shape to fill the paper. I usually scan at 600dpi to ensure that there's always enough info for the final print, after having adjusted resolution to get the correct print size. Personally, I think it's a feature that's missing that should be there, as it's a direct equivalent to cropping a photo using a mask + scalpel.
