Patent ID: 8411113

Claim:
A computer-implemented method for reordering an original set of layered image data for use in rendering a display, comprising: obtaining at a computer device an original set of layered image data comprising multiple original layers of image data arranged to be rendered to form intermediate images prior to the intermediate images being rendered in a display, each of the original layers of image data comprising a plurality of image objects arranged in an intra-layer image object order; executing an image data reordering routine on the computer device that extracts a set of image objects of a first type from two or more of the original layers of image data and creates a set of reordered image data for use as a single reordered layer of image data for use in rendering a display, said reordered layer of image data comprising image objects of the first type ordered as a function of the identity of the original layers of image data from which each of the image objects of the first type was extracted and as a function of the intra-layer image object order of the original layers of image data from which each of the image objects of the first type was extracted; and storing at the computer device said reordered layer of image data.
