Java rotating an ImageBuffer fails

Question

I am trying to rotate an instance of a BufferImage named pic when I try this it resizes and skews and crops the image, any advice to get it to work properly

For use with AffineTransform, you can square an image using something like this:

private BufferedImage getImage(String name) {
    BufferedImage image;
    try {
        image = ImageIO.read(new File(name));
    } catch (IOException ioe) {
        return errorImage;
    }
    int w = image.getWidth();
    int h = image.getHeight();
    int max = Math.max(w, h);
    max = (int) Math.sqrt(2 * max * max);
    BufferedImage square = new BufferedImage(
            max, max, BufferedImage.TYPE_INT_ARGB);
    Graphics2D g2d = square.createGraphics();
    g2d.setRenderingHint(
            RenderingHints.KEY_ANTIALIASING,
            RenderingHints.VALUE_ANTIALIAS_ON);
    g2d.drawImage(image, (max - w) / 2, (max - h) / 2, null);
    g2d.dispose();
    return square;
}
