java - How to rotate JXImagePanel?

Question

I would to rotate JXImagePanel. It should be possible - this is about JXImagePanel:

• Swing :: JXImagePanel

While JLabel and JButton allow you to easily add images to your Swing applications, the JXImagePanel makes it trivially easy to add any BufferedImage or Icon to your Swing applications.

If editable, it also provides a way for the user to change the image. In addition, the JXImagePanel provides many built in effects out-of-the-box, including Tiling, Scaling, Rotating, Compositing, and more.

However, I cannot figure out how to do this. Currently my code snippet is:

bufferedImage = ImageIO.read(new File("image.png"));            
image = new ImageIcon(bufferedImage).getImage();
tempImage = image.getScaledInstance(100, 150, Image.SCALE_FAST);
this.deskJXImagePanel.setImage(tempImage);

Now I would like to rotate it in 0-360 degrees. How it can be done?

Answer 1

JXImagePanel is deprecated (actually, made package private as of 1.6.2, because it's still used internally), so better not use is, will be removed soon.

Instead, use a JXPanel with an ImagePainter and an arbitrary transformOp applied to the painter, in code snippets something like:

    JXPanel panel = new JXPanel();
    ImagePainter image = new ImagePainter(myImage);
    image.setFilters(
            new AffineTransformOp(AffineTransform.getRotateInstance(-Math.PI * 2 / 8, 100, 100), null) 
            );
    panel.setBackgroundPainter(image);

you'll probably have to play a bit to get the exact effects you want to achieve. On problems, you might want to try posting to the Swinglabs forum.
