Well, from a 68 year old youngster, you have a falicy in your comparison. Your monitor displays as xx ppi, usually between 72 and 100, so the image appears very large as you scanned to 24000 ppi. If it is being displayed at 100 ppi, that makes the full image 240 inches wide :^) -- Patrick Shanahan Plainfield, Indiana, USA HOG # US1244711 http://wahoo.no-ip.org Photo Album: http://wahoo.no-ip.org/gallery2 Registered Linux User #207535 @ http://counter.li.org _______________________________________________ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user
