Solved. This was the solution.
private function copypixels(target:BitmapData, src:BitmapData, destP:Point,
targetR:Rectangle ):Boolean{
var toR:Rectangle = new Rectangle(destP.x, destP.y, src.width,
src.height);
var inR:Rectangle = targetR.intersection(toR);
if(inR.width==0 || inR.height==0){return false;} // skip
var srcR:Rectangle = new Rectangle(inR.x-toR.x, inR.y-toR.y,
inR.width, inR.height);
target.copyPixels(src, srcR, new Point(inR.x, inR.y), null, null,
true);
return true;
}
