The Eclipse ImageN project provides an extensible, on-demand image processing library with no artificial restrictions on raster size or number of bands.
ImageN provides:
- High performance Pure Java Image Processing
- Clear image processing operations, allowing installations to use native libs to accelerate processing if available
- On demand processing of large raster content staging tiles in memory for parallel processing
- No artificial limitation on raster size or number of bands to support multi-spectral imagery
Long term continuation of JAI and JAI-Ext:
- Migration refactoring planned
- Modernize Java API planned
This is a Eclipse Foundation open source project using the Apache License v 2.0.

Use maven to build on the command line:
mvn install
The build uses the javac compiler argument -XDignore.symbol.file to reference JDK codecs directly. This functionality is only available from the javac command line and requires maven (or your IDE) to fork each call to javac.
Maven build QA modules:
mvn sortpom:sort
mvn spotless:apply
The ImageN codebase is in the process of being migrated from a Java Extension to a jar compatible with Java "jigsaw" module system.
