%X A free-form image stretching algorithm is presented. By establishing a linear mapping from destinate image to the original image, the algorithm utilizes the rasterlization algorithm of polygons to accomplish the stretch. The algorithm can stretch an original rectangular image into an arbitrary quadrangle. In this algorithm, many basic geometric transformations of digital images are unified. These transformations include scaling, rotating, shearing, flipping, and mirroring, etc. The algorithm can also support some complex geometric transformations by using the image subdividing technique. An example of this is given.
