Build Status

JPEG2000 support for Java Advanced Imaging Image I/O Tools API core jai-imagecore-core.

The jj2000 package in this module is licensed under the JJ2000 license and is therefore not compatible with the GPL 3 license.

WARNING - from the JJ2000 license:

Those intending to use this software module in hardware or software products are advised that their use may infringe existing patents. The original developers of this software module, JJ2000 Partners and ISO/IEC assume no liability for use of this software module or modifications thereof. No license or right to this software module is granted for non JPEG 2000 Standard conforming products.

NOTE: This is a module extracted from the project jai-imageio-core. It depends on the jai-imageio-core module.

There is NO FURTHER DEVELOPMENT in this repository; any commits here are just to keep the build working with recent versions of Maven/Java and to fix regressions against previous releases.

If you are not concerned about GPL compatibility or source code availability, you might instead want to use which is actively maintained and extends the original imageio with many useful features, but depends on the binary distribution of jai_core.
