Abstract
Abstract An improved scanner is presented which enables a user to preview scan a picture and set out on a screen exactly what portion of the picture he desires to scan. The scanner allows a preview scan of the picture to be made. The preview scan presents a preview image. The user is able to specify what portion of the picture he wants by enclosing that portion of the preview image in a box. Then the scanner performs a final scan which scans only the specified portion of the picture. When performing the final scan, the user may select a percentage amount to reduce or enlarge the image when printed as a printed copy. As the user changes the percentage amount, the dimensions of the resulting printed copy are displayed. The dimensions are calculated by determining the dimensions of the portion to be scanned, and reducing or enlarging the dimensions proportionate to the amount the printed copy is reduced or enlarged.
