Question

Hello All,
My code is set up to create an image then save the image into a file in JPEG format. Everything works well except the background of the saved image is balck. How can I get a white background on the saved file?
I have posted my code below. I have allocated 10 duke dollars for the person solves who this? Thank You!!!!

I've added 2 lines to your paint, it works now.
public void paint(Graphics g) {
Graphics2D g2 = (Graphics2D) g;
g2.setRenderingHint(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON);
Dimension d = getSize();
int gridWidth = d.width / 6;
int gridHeight = d.height / 2;
// make a white background
g2.setPaint(Color.white);
g2.fill(new Rectangle2D.Double(0, 0, d.width, d.height));
// fill Rectangle2D.Double (red)
g2.setPaint(Color.red);
g2.fill(new Rectangle2D.Double(100, 100, 100, 100));
g2.setPaint(Color.black);
g2.drawString("My Rectangle", 125, 85);
}
