Aim

The aim of this module is to allow access JP2K data using the Kakadu driver via the imageio-ext-kakadujp2 plugin we have prepared on imageio-ext (Which uses JNI). The underlying data access logics will be based on some of the key objects introduced by Simone on its imagemosaic plugin such as RasterManager, RasterLayerRequest, RasterLayerResponse which are preposed to handle any control/logics involving resolutions/envelope/overviews/crop/requests/... management.

Future plans

The idea is to proceed with improvements and tests on the previously introduced concepts/objects in order to extract a base architecture which may be shared by plugins to access coverages.
Example of future tasks during the development of the plugin include:

  • gmljp2 parsing
  • multiple codestreams access capabilities (Mainly for jpx format)

Leveraging Kakadu

Kakadu is a powerful implementation of the JPEG2000 standard.
It also allows to build a set of JNI DLLs which may be used via Java through a Jar package containing bindings to the native libs. Our ImageIO-Ext kakadu plugin is based on this.
(The imageio-ext site already contains information about the Kakadu capabilities as well as instructions on how to setup and build the required kakadu native libs.)

The Image I/O-Ext project

The Image I/O-Ext project leverages existing native APIs to extend the set of formats that the JAI ImageIO API can read.
Actual version of Image I/O-Ext is 1.0.4.
