About the Djatoka Jpeg 2000 Image Server

djatoka is a Java-based open source image server with an attractive basic feature set and extensibility under control of the community of implementers. Off-the-shelf, djatoka provides compression and region extraction of JPEG 2000 images, URI-addressability of regions, and support for a rich set of input/output image formats (e.g., BMP, GIF, JPG, PNG, PNM, TIF, JPEG 2000). djatoka also comes with a plug-in framework that allows transformations to be applied to regions and resolutions (e.g., watermarking).
