djatoka: Open Source JPEG 2000 Image Server

Important Development in JPEG2000 Support

I don't know about you, but UPEI has been waiting for something like this new JPEG2000 server app for awhile. We are ramping up for a number of high-volume, high-profile digitization projects, and having an open source server has been a key requirement for our plans. djatoka looks very promising and has a number of key features - from the paper:

• Compression of JPEG 2000 files using the Kakadu JPEG 2000 Library with properties to improve extraction performance and good compression/quality balance;
• Dynamic extraction of multiple resolutions and Regions from JPEG 2000 files;
• Support for a rich set of input/output formats (e.g., BMP, GIF, JPG, PNG, PNM, TIF, JPEG 2000) through the use of the ImageJ, Java Advanced Imaging, and the Kakadu JPEG 2000 Library;
• Extensible interfaces to request image services and manipulations (e.g., watermarking);
• A rich service framework, based on the OCLC OpenURL Resolver, to facilitate the transfer of service parameters via an OpenURL compliant HTTP GET request.
• Configurable File-based Caching for improved performance.
