Abstract
Apparatusis disclosed for rendering an object-based image one pixel at a time in scanline order. The apparatuscomprises an optimisation modulefor generating a set of compositing messages during a first pixel in a run of pixels between adjacent edges of one or two objects, and for generating a reduced set of compositing messages from the set during subsequent pixels in the run of pixels. The apparatusfurther comprises a pixel compositing modulewhich in addition to compositing the first pixel in the run of pixels also stores a result or partial result of the compositing of the first pixel. The pixel compositing moduleutilises the reduced set of compositing messages and the stored result or partial result to composite pixels in the run subsequent to the first pixel.
