56VISIONEER STROBE XP 450 SCANNER USER’S GUIDE
Straighten Image—Select this option to let the scanner automatically determine if a page is skewed, and then straighten its image. The scanner detects page edges and can sense when the page is fed through at an angle. However, if the page is fed through at too great an angle, the image may not straighten correctly. In that case, re-scan the page using the paper guides to feed the paper in straight.
Invert Image—Only available for Black&White Mode, this option reverses the black and whites of an image.

Color Filter—Color filter is the ability of your scanner to automatically remove a color from a scanned item. For example, if you are scanning a letter with a red watermark, you can choose to filter out the red so the scanned letter just shows the text and not the red watermark. Color filter applies to Black&White or Grayscale Mode.
