JIU, the Java Imaging Utilities, is a library which offers functionality to load, analyze, process and save pixel images. It is written in Java and comes with full source code under the GNU General Public License (GPL) version 2. JIU requires Java version 1.1 or higher.
This is a really neat little utility for the Java programmer. It embeds binary image files (such as JPEGs, PNGs and GIFs) into Java source files. No more worries about your code not finding the image file - it's right there in your source code! Ideal for applets!
ImageApp is an attempt to allow users to build up these image processing graphs using drag and drop. It uses the excellent library from Sun called Java Advanced Imaging (JAI) and also in the latest version an excellent graph API called JGraph.
