[gdal-dev] JPEG2000 change progression order without decoding

I wonder if there is a way to change the progression order of jpeg2000
images, without the need of decoding it and then encode it again. For
example if I have an image with RPCL progression and I want to convert it
to LRCP. Is there a way to only move bits around (change the order of the
file) instead of needing to transcode the image all over again (which may
take a long time)?

Thanks in advance,
Tobby
