- 43 FAST ROTATED BITMAP RENDERING Disclosed is a method of rendering a transformed image, comprising storing pixel data of an original bitmap image into a memory and calculating each pixel position in the transformed image based on a corresponding pixel position of the original bitmap image and at least a transformation factor. The method associates, for example by tagging, each calculated pixel position of the transformed image with a pixel of the original bitmap image. The method then reads from the original bitmap image stored pixel data corresponding to the associated pixel of the transformed image in order of the original bitmap image, and renders the transformed image data using the read pixel data. 0_ U) 0) >1 a) 0_ aa) -~ ) r C),CD -oN 0 a0 Ci~T, |
