The invention relates to a method and an apparatus for processing image data stored on a memory for rendering an image on a device. The method comprises dividing the image data into a number of portions of image data, each portion consisting of a number of untruncated data lines; applying to each portion of image data a rasterizing algorithm comprising: a. writing the portion of image data to a RAM, b. halftoning said portion of image data for obtaining a portion of rasterized image data, and c. writing the portion of rasterized image data to a mass memory; assembling the portions of rasterized image data on the mass memory for obtaining rasterized image data; dividing the rasterized image data into a number of blocks; and applying a transformation algorithm to each block of rasterized image data for obtaining blocks of processed image data.
