Usage

From source file:Main.java

public static void main(String[] argv) throws Exception {
    BufferedImage bufferedImage = new BufferedImage(200, 200, BufferedImage.TYPE_BYTE_INDEXED);

    AffineTransform tx = new AffineTransform();
    tx.rotate(0.5, bufferedImage.getWidth() / 2, bufferedImage.getHeight() / 2);

    AffineTransformOp op = new AffineTransformOp(tx, AffineTransformOp.TYPE_BILINEAR);
    bufferedImage = op.filter(bufferedImage, null);
