Abstract:
1. A method of processing image data in a compositing environment comprising: recurrently selecting, in a continuation manager of an image processing system in a compositing environment, each of a plurality of data processing modules for execution in the order of dependencies of the plurality of data processing modules based on a process tree; recurrently selecting, in said continuation manager, each of a plurality of sub-processes within each of said data processing modules for execution based on the process tree; determining if the selected sub-process requires input data from another of the plurality of sub-processes; when the selected sub-process requires input data, determining if the sub-process processes the required input data; generating an error if the sub-process is unable to process the required input data; and generating output data at each of said selected sub-processes in the order of said dependencies.
