kdu_region_compositor::halt_processing

Call this function if you want to use any of the internal codestreams in a manner which may interfere with internal processing. For example, you may wish to change the appearance, open tiles and so forth. The effects of this call will be entirely lost on the next call to process. A similar effect can be obtained by calling refresh, except that this will result in everything being decompressed again from scratch in subsequent calls to refresh. The present call may discard some partially processed results, but leaves all completely processed image regions marked as completely processed.
