What is Skew?
Skew meaning in Digital terms is The angle of deviation in a digital image from the paper edge, text lines or other visual reference elements. Skew is expressed numerically as the tangent of the deviation angle in degrees, either clockwise or counterclockwise. It applies to the angle of two-dimensional image orientation. Skew is a common occurance in automatic document feeder scanning when the paper deviates from the paper path.
