Anatomy the script

<script type="text/javascript" src="QRCode.js"></script>
<script type="text/javascript">
var qr;
function generate(str){
	qr = new QRCode(4, QRErrorCorrectLevel.H);
	qr.addData(str);
	qr.make();
}
function count(){
	return qr.getModuleCount();
}
function isDark(r, c){
	return qr.isDark(r, c);
}
</script>

The isDark() method in a container can be invoked to make actionscript know the color of the dot for setting pixels with black and white in bimap to view.

ExternalInterface.call("generate", str);
var count:Number = Number(ExternalInterface.call("count"));
var bitmap:BitmapData = new BitmapData(width, height, true);
this.createEmptyMovieClip("c", 1).attachBitmap(bitmap, 1);
for(var r:Number = 0; r < count; r++){
   for(var c:Number = 0; c < count; c++){
      var col:Number = 
      Number(ExternalInterface.call("isDark", r, c)) ? 0x00000000 : 0x00ffffff;
      bitmap.setPixel((width - count) / 2 + c, (height - count) / 2 + r, col);
   }
}
