This is a fork of JPedal's JBIG2 library, which aims to improve the performance of the original code.

Version 1 (09.10.2011):

In all samples we have tested, the decoding speed has increased at least by factor 2.5. In some examples a speed up by factor 4.5 was observed.

There is still lot of room for improvements especially in the combine method in JBIG2Bitmap, which is most time consuming.
