Flashpaper size in AS3

Regards.

I have some pdf documents that have been converted to flashpaper, I’m using a little AS3 code to include in flash, however the size does not match the original file; anyone can help me please?

i try load the swf (flashpaper file) into 800x600 movie, but not works, btw there is the code and screenshot

var url:String = "concepto_001-2007.swf";
var urlRequest:URLRequest = new URLRequest(url);
var loader:Loader = new Loader();
loader.contentLoaderInfo.addEventListener(Event.COMPLETE, loader_complete);
loader.load(urlRequest);
fla.addChild(loader);
 
function loader_complete(evt:Event):void {
    var target_mc:Loader = evt.currentTarget.loader as Loader;
    target_mc.x = 0;
    target_mc.y = 0;
	trace(target_mc.width);
	trace(target_mc.height);
	}
