I have not done this with an image, but have done similar with text.
Give it a try:
public void paint(Graphics g) {
// we need the extended graphics features, I think...
Graphics2D g2 = (Graphics2D) g;
// Assume I have an image that is 100 x 100
// Move the origin to the middle of the picture
// in reality, you will have to move to one corner, but I forget
which
g2.translate(50, 50);
// rotate the drawing mechanism about the origin
g2.rotate(Math.PI / 2);
// draw the image
g2.drawImage(myImage);
// de-rotate and de-translate the paper
g2.rotate(-Math.PI / 2);
g2.translate(-50, -50);
}
Steve.
