Utilization of caching in image manipulation and creation

摘要

A method of increasing the speed of image creation on a computer system for the interactive creation of images via a series of creation steps. A resultant image of each of the creation steps is copied to a corresponding separate storage buffer. When making an amendment to the series of creation steps previously performed, one or more of the resultant images is used, so as to reduce the rendering time of producing a final output image.
