|Preview Pane displays a preview of the scanned image or document. When you click Prescan, the source image or document is scanned at low resolution. A low-resolution copy of the original image is displayed to let you see the whole page you get from the scanner.|
The vertical and horizontal rules displayed at the sides of Preview Pane allow you to estimate the image linear size. When you enlarge or reduce image size, or select other units, the rules are automatically adjusted to reflect the changes.
When you apply visual effects or filters to the image, select an area to scan, zoom the image in or out, rotate or flip it, adjust the image brightness, contrast, highlight, shadow and gamma, and apply blur or sharpness filters, the results of your current operations are displayed in the Preview Pane.
