CornerPoints # get and set (PerspectiveCommand)
Array of Leadtools.LeadPoint values that determine the new locations of image corners. It should contain four points; points at indices 0, 1, 2 and 3 determine the new locations of left-top, right-top, left-bottom and right-bottom image corners respectively. The new locations of image corners should keep the relative relation between corners: for example, the point at index 1 should be to the right of the point at index 0 and up from the point at index 3. Also, the point at index 2 should be to the left of the point at index 3 and down from the point at index 0 and so on. All new locations should be inside the image.
