Question

Given an Applet object, is it possible to programatically obtain a “screen shot” of the applet window (represented as say a BufferedImage)?

 JApplet applet = this;
 // ... code here ...
 BufferedImage screenshotOfApplet = ...;

Answer 1

You could use Robot.createScreenCapture(Rectangle bounds) – however, the applet would have to be signed to allow this to work once deployed.

After comments –

If you just want the applet component –

You can create a BufferedImage and paint to it – something like this:

public static BufferedImage imageFor(Component component) {
    BufferedImage image = new BufferedImage(component.getWidth(), 
            component.getHeight(), BufferedImage.TYPE_INT_RGB);
    Graphics g = image.getGraphics();
    component.paint(g);
    return image;
}

I’m not sure if this would require the applet to be signed or not…
