Detailed Description

Maps points from one rectangle to another rectangle. This class represents a relation between the points of two rectangles. Given the coordinates of a point in the first rectangle (input rectangle), function {map} computes the coordinates of the corresponding point in the second rectangle (the output rectangle). This function actually implements an affine transform which maps the corners of the first rectangle onto the matching corners of the second rectangle. The scaling operation is performed using integer fraction arithmetic in order to maximize accuracy.
