jpeg-6c:  This is a version of jpeg-6b that the bit width can be changed without recompiling.  It supports 8 and 12 bits for lossly and 2-16 bits for lossless.  The defaults are for 8 bit outputs to be compatible with most code.  Do not apply other patches to it, as a lot has changed.  The lossless and crop patches were applied before I made changes.  The document file in the zip package describes how to use the other file widths, also rdppm.c and wrppm.c were changed to read and write multiple widths as examples.  I made other changes so it would compile on my Mac under GCC 4.0.1 without warnings.  If you have questions or bugs, contact me at bruce.barton at bitsltd.net

jasper-1.900.1-6c: These are just the files that I changed to make it work with jpeg-6c and to lessen gcc4 compiler warnings (still 3 left).  It allows 8 and 12 bits lossy and lossless jpeg files.  It also works with 16 bits lossless files.  The files changed for jpeg-6c are jpg_dec.c and jpg_enc.c, all other file changes for compiler warnings.

dgate 1.4.16alpha3 is out.  This is a zip file of the files changed for use with the Conquest DICOM software 1.4.16alpha3, written by Marcel van Herk and Lambert Zijp at the Netherlands Cancer Institute.  They allow dgate to use the openjpeg library in place of the Jasper library.  This enables the main program at the heart of Conquest (dgate) to process jpeg2000 images faster and a few more types of jpeg2000 images are also understood.  For now it is an alpha release because I didn't have access to all the different type of uncompressed images allowed by the standard.  I have tested it on a big endian, 32 bit, power pc; little endian Intels, 32 and 64 bit, running different versions of Apple's OSX.
