1. A method, comprising: rotating an original image in an image frame by an angle to have a rotated image in said image frame, wherein said image frame comprising said rotated image has empty corners lacking image data; comparing the rotated image to the original image to identify remaining corners; adding content of the remaining corners to the empty corners of the image frame comprising said rotated image, wherein the content comprises line-detected and adjusted information associated with the original image; and adjusting the content of the remaining corners by shrinking content of the remaining corners with a predetermined scaling factor to compensate for reduced length caused by rotation, wherein the predetermined scaling factor applies to the remaining corners of the rotated image while maintaining unaltered original dimensions of other portions of the rotated image.
