I have Xsane 0.84 on Red Hat 8.0 and when I scan an image of a photo, it procuces an image of an A4 sheet, with the photo in the middle. How do I just cut the photo image out and save that, rather than the whole sheet? I have had a look at the preview, and I can select the autoscan area and zoom in, but how do I save it? Regards, Brad
