Preview

By clicking on the Preview button, you can scan the source document into the Preview Window within TWAIN interface. This allows you to modify the scan area (for smaller images such as photographs) and gives you a rough idea of what the scanned image will look like before you scan.

After you have prescanned a document or photo and it appears in the Preview Window you can adjust settings (except for Rotate, Flip, Filter and Descreen) and immediately view these new settings on the image in the Preview Window so you can judge the effects of the different settings before you finally scan.
