Correcting an area of a scanned image by entering three points

Module(s): Scan

You can use the 3-Point Correct tool to correct an area of a scanned image by entering three points.

• When you employ the 3-Point Correct tool to re-align an area of the image, the file containing the image is also modified. You should therefore use Copy Image to make a backup copy first.

• Before you perform this operation, you should set the zoom factor so that the image is roughly the required size.
  Use Link with Scanned Image to do this and adjust the zoom factor as necessary.
