creating an image from the screen?

I'm deeply sorry for this post. I know that probably this subject as already been discussed, described everywhere and it should be darn damn simple. But my brain is refusing to work today, and so does my sketches...
How do I transform my screen into a BImage object?

Before an image is used, it must be loaded with the loadImage() function.
So I guess if you had a blank the same size as your drawing space in the data folder. You could do this:
Code:
BImage swap;
void setup(){
swap = loadImage("a.gif");
size(swap.width,swap.height);
swap.pixels = pixels;
}
void loop(){
ellipse(mouseX,mouseY,10,10);
image(swap,1,0);
}
void mousePressed(){
background(255);
}

But I can't seem to get the swap image to take a static snap shot. Referencing the screen pixels[] creates a permanent link. Suggestions?
Update - Whoops:
http://processing.org/reference/copy_.html
Even wierder - using copy to initialise the BImage means it won't scroll
Code:
BImage swap;
void setup(){
size(100,100);
swap = copy();
swap.pixels = pixels;
}
void loop(){
ellipse(mouseX,mouseY,10,10);
image(swap,1,0);
}
void mousePressed(){
background(255);
}
