bitmapData.draw(mapcontainer,new Matrix());	

var file:FileReference = new FileReference();

var ba:ByteArray = jpg.encode(bitmapData);

var urlrequest: URLRequest = new URLRequest(uploadImgUrl + "?id="+appId);
urlrequest.method = URLRequestMethod.POST;

var loader:URLLoader = new URLLoader();
loader.addEventListener(Event.COMPLETE,finishCaptureUpload);
loader.load(urlrequest);
