Abstract
Disclosed is a method of printing a transformed image corresponding to a source image. The method determines at least a first scale factor to upscale the source image to generate the transformed image, the first scale factor being at a first mathematical precision. The source image is enlarged along at least one edge of said source image edges and pixel data is copied along the source image edges into the enlarged area of the enlarged source image. The method maps each pixel of the transformed image back to a corresponding pixel into the enlarged source image including the copied pixel data along the edge of the source image. The method may determine a second scale factor, the second scale factor being at a second mathematical precision, wherein each pixel of the transformed image is mapped back to a corresponding pixel in the enlarged source image using the second scale factor.
