This image operation will automatically try to detect a solid border around the outside of an image and crop it out of the image. This is particularly useful for cropping scanned images that are bordered with the scanner backing.

EyeBatch will attempt to automatically detect the border color, or it can be manually detected.

• Color Match Tolerance is the border color tolerance that EyeBatch uses to determine the exact border.
• Force Border Color can be selected to manually choose a border color
