Usage

From source file:AppSpringLayout.java

protected BufferedImage mirrorImage(BufferedImage imageToFlip) {

    // Flip the image horizontally
    AffineTransform tx = AffineTransform.getScaleInstance(-1, 1);
    tx.translate(-imageToFlip.getWidth(null), 0);
    AffineTransformOp op = new AffineTransformOp(tx, AffineTransformOp.TYPE_NEAREST_NEIGHBOR);
    imageToFlip = op.filter(imageToFlip, null);

    return imageToFlip;
