J2000: A JPEG-2000 Codec
Welcome to the home of the J2000 codec.The J2000 codec was written
in an effort to produce the cleanest and simplest implementation possible of the
JPEG-2000 standard. We have put a particular emphasis on good architecture
design and code simplicity, while at the same time providing an implementation
as complete and efficient as possible. The source code for the codec is freely
available for anyone to study or even for use in commercial programs. We hope
that our open development process and our focus on clean, straightforward code
will help make the J2000 codec become a reference implementation of the
JPEG-2000 standard.NEW: Please use the href="http://j2000.org/forums">discussion board to post your questions and
