Rotating an Image in java

Question

I have an image of a Pan Card and when I try to rotate it by 45 degrees and save it, I get a cropped image. Code to rotate an image is:

    BufferedImage dim         


        

Answer 1

Have a look at this example, using AffineTransform:

there's some code to load the image, then this is the core:

private Image image;
AffineTransform identity = new AffineTransform();

Graphics2D g2d = (Graphics2D)g;
AffineTransform trans = new AffineTransform();
trans.setTransform(identity);
trans.rotate( Math.toRadians(45) );
g2d.drawImage(image, trans, this);
