Foil 90 Double Buffering to Reduce Flicker - II

From CPS616 Lectures on Java CPS616 Basic Information Track for Computational Science -- Winter-Spring Semester 96. by Geoffrey C. Fox * See also color IMAGE

The previous statements could be in init() while in paint(), one will construct applet image in offscreenGraphics as opposed to the argument g of paint(). So one would see statements such as:
e.g. offscreenGraphics.drawImage(img,10,10,this);
Finally at end of paint(), one could transfer the double buffered image to g by
g.drawImage(offscreenImage,0,0,this);
One would also need to override the update() method by
public void update(Graphics g) {
paint(g);
}
