A method of creating an image is disclosed. The image is formed by rendering and compositing at least a plurality of graphical objects whereby each of the objects has a predetermined outline. The method comprises the following steps. Firstly, dividing a space in which the outlines are defined into a plurality of regions whereby each of the regions is defined by at least one region outline. The region outline substantially follows at least one of the predetermined outlines or parts thereof and is substantially formed by segments of a virtual grid encompassing the space. Secondly, manipulating the regions to determine a plurality of further regions whereby each of the further regions has a corresponding compositing expression. Fourthly, classifying the further regions according to at least one attribute of the graphical objects within the further regions. Fifthly, modifying each of the corresponding compositing expressions according to a classification of each of the further regions to form an augmented compositing expression for each of the further regions. Finally, compositing the image using each of the augmented compositing expression. |
