Hi,

I have some problem connected with translating
BufferedImage by JAI lib. Below is my code:

ParameterBlock pb = new ParameterBlock();
pb.addSource(image); <--my BufferedImage
pb.add(8f);
pb.add(0f);
pb.add(new InterpolationNearest()); // The interpolation

// Create the translate operation
RenderedOp op = JAI.create("translate", pb, null);
image = op.getAsBufferedImage();

// Below I would like to change images.
imageScrollPane.getViewport().remove(imagePanel);
imagePanel = new ImagePanel(image);
imageScrollPane.getViewport().add(imagePanel);
imageScrollPane.getViewport().repaint();

ImagePanel inherited from JPanel.
----------------------------------------------------
It do nothing, the image is the same like earlier.
What is wrong ?

Regards gWW
