Support to decode only certain regions has been removed. The only advantage was a smaller destination buffer and an optional quicker return. The JPEG-LS algorithm can only decoded starting from the beginning, so no real performance gain was made. Typical scenario is to decode complete image. If needed user code can perform a post processing step to extract a region is needed.
