This directory contains a subset of the OpenJPEG project (http://www.openjpeg.org/).
The OpenJPEG library is an open-source JPEG 2000 codec written in C language. It
has been developed in order to promote the use of JPEG 2000, the new still-image
compression standard from the Joint Photographic Experts Group (JPEG). In
addition to the basic codec, various other features are under development, among
them the JP2 and MJ2 (Motion JPEG 2000) file formats, an indexing tool useful
for the JPIP protocol, JPWL-tools for error-resilience, a Java-viewer for
j2k-images, ...
The library is developed by the Communications and Remote Sensing Lab (TELE),
in the Université Catholique de Louvain (UCL).
We only include enough of distribution to build libopenjpeg. For instance we do not
include the codec subdirs.
Furthermore, the standard OpenJPEG build process is replaced with a lightweight CMake process.
We'd like to thank the OpenJPEG project for releasing an open source
implementation of the JPEG2000 codec. In particular, thanks to Antonin Descampe
for fixing the 'well known' 16bits j2k issue.
The current version is based on SVN revision 1111
OpenJPEG THANKS file
Many people have contributed to OpenJPEG by reporting problems, suggesting various improvements,
or submitting actual code. Here is a list of these people. Help me keep
it complete and exempt of errors.
