A method ( 700 ) of compositing a group of graphical objects onto a background image, in accordance with an embodiment of the present invention, is disclosed. The method ( 700 ) allows a grouped plurality of objects to be composited onto a background image to produce the same result as if each of the objects had been rendered separately onto the background image. In particular, the method ( 700 ) allows such a composition to be performed when an operation is to be applied to a grouped plurality of objects as a whole. The principles of the method ( 700 ) have general applicability to any rendering system that accepts input graphical objects and generates a final image.
