How to rotate image in java?

Question

I'm new to java. I would like to load an image from file. Rotate it certain degrees and re wite it to a file and Not display onscreen. But with a large number of classes in java, I don't know where to start. Presently I know of loading and writing a buffered image. Does anyone have any tutorials about rotation and saving without display ? TIA

Use ImageIO to read the image.

Use AffineTransformOp to rotate a BufferedImage.

Finally, write the image back, using ImageIO.

AffineTransform transform = new AffineTransform();
transform.rotate(radians, bufferedImage.getWidth()/2, bufferedImage.getHeight()/2);
AffineTransformOp op = new AffineTransformOp(transform, AffineTransformOp.TYPE_BILINEAR);
bufferedImage = op.filter(bufferedImage, null);

Use Image Magic java API to do all image manipulations you want to do. Here is the link http://sourceforge.net/apps/mediawiki/jmagick/index.php?title=Main_Page
