Question

I have an Image on a JPanel. I’m then drawing a rectangle on top of the image like this:

Graphics2D image = (Graphics2D) g;
image.drawRect(......);
//create image code here.
image.rotate(1.5);
image.drawImage(....);

Problem is that when I rotate the image image.rotate(1.5), the rectangles stay in the same place.

I’ve tried creating the rectangle before rotating the image and after rotating the image, but both times it fails.

Is there an easy way to make the rectangles also rotate along with the image?

Thanks.

One approach is to rotate the graphics context’s affine transform, as shown in this example. In that way, all drawing will be rotated by the same amount.
