Method of rendering graphic objects

A method of rendering an image described by a list of graphical objects includes the steps of assigning objects in the list to at least one of a first set of objects and a second set of objects, and rendering the first set of objects to an image store using a first rendering method that determines whether a portion of an object of the first set contributes to a rendered output of the first set of objects and, if so, the first rendering method renders each pixel of the portion in sequence. The second set of objects to the image store are rendered using a second rendering method that renders each object in the second set in sequence and independently of the other objects in the second set.
