[]使用UrlLoader加载图片，flash获取data为byteArray，翻译成h5后data为image？

package

{

	import flash.display.Bitmap;

	import flash.display.Loader;

	import flash.display.Sprite;

	import flash.events.Event;

	import flash.net.URLLoader;

	import flash.net.URLLoaderDataFormat;

	import flash.net.URLRequest;

	import flash.utils.ByteArray;

	

	public class UrlImage extends Sprite

	{

		private var urlLoader:URLLoader;

		private var l:Loader;

		public function UrlImage()

		{

			super();

			if(stage)

			{

				init();

			}

			else

			{

				this.addEventListener(Event.ADDED_TO_STAGE,init);

			}

		}

		private function init(e:Event=null):void

		{

			urlLoader=new URLLoader();

			urlLoader.dataFormat=URLLoaderDataFormat.BINARY;

			urlLoader.addEventListener(Event.COMPLETE,onImageLoaded);

			urlLoader.load(new URLRequest("screen.png"));

		}

		

		private function onImageLoaded(event:Event):void

		{

			// TODO Auto-generated method stub

			trace(event.target.data is ByteArray)

			var ba:ByteArray=event.target.data as ByteArray;

			l=new Loader();

			l.contentLoaderInfo.addEventListener(Event.COMPLETE,onImage2Loaded);

			l.loadBytes(ba);

			urlLoader.removeEventListener(Event.COMPLETE,onImageLoaded);

			urlLoader=null;

		}

		

		protected function onImage2Loaded(event:Event):void

		{

			// TODO Auto-generated method stub

			var bitmap:Bitmap=event.target.content as Bitmap;

			addChild(bitmap);

			l.contentLoaderInfo.removeEventListener(Event.COMPLETE,onImage2Loaded);

			l=null;

		}

	}

}
