flex添加gif图片

GifPlayer下载:http://code.google.com/p/as3gif/downloads/list，如图，提取org文件夹并放在程序目录src下面就可以了。

实例一：简单添加gif

<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009" 
			   xmlns:s="library://ns.adobe.com/flex/spark" 
			   xmlns:mx="library://ns.adobe.com/flex/mx" minWidth="955" minHeight="600">
	<fx:Script>
		<![CDATA[
		import org.bytearray.gif.player.GIFPlayer;
			
		private var gifPlay:GIFPlayer=new GIFPlayer();
		private function init():void{
		var req:URLRequest=new URLRequest("../flex_src/images/复件-雨量图标.gif");
		gifPlay.load(req);
		gifImg.addChild(gifPlay);  
		} 
		]]>
	</fx:Script>
	<mx:TitleWindow title="abc" id="ADwindow" width="1000" height="800" >
		<mx:Image id="gifImg" width="221" height="92" creationComplete="init()"/>
	 </mx:TitleWindow>
</s:Application>

实例二：演示了几个常用的功能:播放、停止、到第几帧播放、到第几帧停止。
