            Description

            The JBIG2 image format is a bi-level (black/white) image compression. It offers significant advantages over other compress types and is becoming more and more popular as the next fax format standard. We currently don't support this format but should probably start thinking about it.

                It looks like there are been some advances in JBIG2 Java Library support. Surprisingly JPedal has release a JAI JBIG2 Image Decoder plugin under BSD license.

                Evaluated JPedal JBIG2 library, and it works with the test JBIG2 files that we have. Added license file into our docs/licenses directory. Added library package into our subversion.

                Integrate with 3rd party library we're using for JBIG2 support. The JBIG2 library seems to do unnecessary memory allocations, so we'll come back later and optimise that. In the mean while, we'll integrate at the highest level possible.

                Profiled typical memory usage spikes, and added the appropriate calls to the memory manager to handle them. Reduced the memory spike involved in deriving the BufferedImage from the decoder's internal data structures.
