"image4" is BufferedImage.
"Ltab" is a LookupTableJAI.

...
RenderedOp img = JAI.create("AWTImage", (Object)image4);

PlanarImage jo = img.getRendering();

ParameterBlock pb = new ParameterBlock();

pb.addSource((Object)jo);

pb.add(Ltab());

pb.add(KernelJAI.ERROR_FILTER_FLOYD_STEINBERG);

RenderedOp imop = JAI.create("errordiffusion", pb, null);

PlanarImage dst = imop.getRendering();

BufferedImage gus = dst.getAsBufferedImage();

image4=gus;

Problem is, this makes no difference what so ever to my image. It still uses the wrong colors, instead of beeing dithered to my lookuptable colors. Thanks for any help.
