Java select Area of BufferedImage

Hi everybody,

I made a JFreeChart chart and put it into a BufferedImage

Code:

---

ChartRenderingInfo info = null;
label.setIcon(new ImageIcon(chart.createBufferedImage(400, 400, info)));

---

now I wan't to lay a slider on top of it which i can drag among the BufferdImage so that i can select an area with it.

Do you have any idea where I can find that?

Already did a lot of Google research but either I'm too stupid or there is no way for BufferedImages to do this.

Thanks in advance
