A method and apparatus for arbitrary transformation of images comprises a transformation between a source image and a destination image. Variables which define the transformation are obtained. A first value and a second value are then determined from the variables. An initial pixel is initialized and destination vectors are determined for the initial pixel. For each remaining pixel to be transformed, the first value is added to the x component and the second value is added to the y component of the destination vectors that correspond to the pixel being transformed. The method and apparatus for arbitrary transformation of images thereby reduces the number of calculations that need to be performed for such operations to two additions only.

A method for transforming a scan line in a first image into a second image, wherein the scan line in the first image is comprised of at least one pixel, said method comprising the steps of: receiving transformation data, wherein the transformation data defines the type of transformation to be performed on the scan line in first image; determining an initial pixel location in the scan line in the first image; determining at least one initial destination vector using the transformation data and the initial pixel location; determining a pixel location in the second image using the at least one initial destination vector; determining a first value, wherein the first value remains constant throughout the transformation of the scan line in the first image; determining a second value, wherein the second value remains constant throughout the transformation of the scan line in the first image; for each remaining pixel in the scan line in the first image, determining at least one destination vector for each remaining pixel using the first and second values and the at least one initial destination vector; and for each remaining pixel in the scan line in the first image, determining a pixel location in the second image by using the at least one destination vector determined for each remaining pixel.
