flex 的融合blendMode使用

?在Flex4.5中实现的一个简单的例子:
<?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:Declarations>
??<!-- 将非可视元素（例如服务、值对象）放在此处 -->
?</fx:Declarations>
?<mx:HBox? label="blendMode:">
??<s:ComboBox id="comboBox" selectedIndex="0">
???<s:dataProvider>
????<s:ArrayCollection>
?????<fx:String>{BlendMode.ADD}</fx:String>
?????<fx:String>{BlendMode.ALPHA}</fx:String>
?????<fx:String>{BlendMode.DARKEN}</fx:String>
?????<fx:String>{BlendMode.DIFFERENCE}</fx:String>
