Hello there please take a look at http://www.indiegogo.com/projects/painty/x/1680012. Its my image editor entirely written in Java using Swing and many open source libraries. Im developing it as photoshop replacement. Write what do you think about my project, im able in about 6 months to extend functionality to actually met Photoshop but I need little support.
At the moment program utilize imagemagick parser im4java, Jmagick, Geotools. Loci Bioformats and ImageIO addons for reading/writing images. JAI, JAITools and basic Java2D functionality for handling image manipulation and also for cacheing very big bitmaps on disc.
