Flex加载图片

Flex使用Loader和URLRequest加载本地图片示例：
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"
layout="absolute">
<mx:Script>
<![CDATA[
import mx.core.UIComponent;
import mx.controls.Alert;
import flash.display.*;
import flash.net.URLRequest;
 
 
var ldr:Loader;
private function Load():void
{
     ldr= new Loader();<span id="more-684"></span>
              
     var url:String="tuzi.jpg";
     var urlReq:URLRequest=new URLRequest(url);
 
     ldr.load(urlReq);
     ldr.contentLoaderInfo.addEventListener(Event.COMPLETE, completeHandler);
 
}
 
private function completeHandler(e:Event):void
{
    //mx.controls.Alert("load");
    var uc:UIComponent=new UIComponent();
    uc.addChild(ldr);
    thePanel.addChild(uc);
 
    ldr.scaleX*=thePanel.width / ldr.width;       //按照比例缩放
    ldr.scaleY*=thePanel.height / ldr.height;
 
 
    ldr.contentLoaderInfo.removeEventListener(Event.COMPLETE, completeHandler);
 
}
]]>
</mx:Script>
