Drawing a BufferedImage on itself doesn't work....!?

[Clemens]

Hi,
Can anybody explain why that doesn't work:

BufferedImage img = new BufferedImage(100,100);
Graphics2D gfx = img.createGraphics();

gfx.drawImage(img.getSubimage(0,50,100,50), 0, 50, null);


I don't know any other possibility to trim an image, do you?

Any idea?
