给 Flex Label 控件添加阴影滤镜
一、声明方式：
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" xmlns:flash="flash.filters.*">

<mx:Label text="DropShadowFilter" fontSize="20">
<mx:filters>
<flash:DropShadowFilter distance="10" angle="45"/>
</mx:filters>
</mx:Label>

<mx:Label text="DropShadowFilter (inline)" fontSize="20" filters="{[new DropShadowFilter(10, 45)]}"/>
</mx:Application>

二、编程方式：
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml">

<mx:Script>
import flash.filters.*;

public function addFilter() : void
{
var f:DropShadowFilter = new DropShadowFilter(5,30,0xFFFFFF,.8);
var myFilters:Array = new Array();
myFilters.push(f);
label1.filters = myFilters;
}
</mx:Script>

<mx:Label id="label1" text="ActionScript-applied filter"/>
<mx:Button id="b1" label="Add Filter" click="addFilter()"/>
</mx:Application>

大家查一下flash.filters.DropShadowFilter类的帮助文档便可知道该类构造方法的参数含义。
