swf data’s from ByteArray

After spending 4 hours i got the code from senocular.com . how to read the data from the swf.
if we use UrlLoader to load the Swf as byte Array. it will tough to get back the Details from the ByteArray.

private var swfReader:SWFReader;
private var swfUrlLoder:URLLoader;
// intialize the Loader…
loader = new URLLoader();
loader.dataFormat=URLLoaderDataFormat.BINARY;
loader.addEventListener(Event.COMPLETE, onSWFLoaded);
loader.load(new URLRequest(“Test.swf”));
loader.addEventListener(ProgressEvent.PROGRESS,getProgressive);
private function onSWFLoaded(e:Event):void
{

swfUrlLoder = URLLoader(e.target);
swfReader = new SWFReader(swfUrlLoder.data);
trace(swfReader.width+” === “+swfReader.height)
}
