Welcome to the Djatoka Jpeg 2000 Image Server project wiki. This wiki intends to centralize all the knowledge about djatoka, and the clients and server extensions being developed.


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).
