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>
     <fx:String>{BlendMode.ERASE}</fx:String>
     <fx:String>{BlendMode.HARDLIGHT}</fx:String>
     <fx:String>{BlendMode.INVERT}</fx:String>
     <fx:String>{BlendMode.LAYER}</fx:String>
     <fx:String>{BlendMode.LIGHTEN}</fx:String>
     <fx:String>{BlendMode.MULTIPLY}</fx:String>
     <fx:String>{BlendMode.NORMAL}</fx:String>
     <fx:String>{BlendMode.OVERLAY}</fx:String>
     <fx:String>{BlendMode.SCREEN}</fx:String>
     <fx:String>{BlendMode.SHADER}</fx:String>
     <fx:String>{BlendMode.SUBTRACT}</fx:String>
    </s:ArrayCollection>
   </s:dataProvider>
  </s:ComboBox>
 </mx:HBox>
 
 
 <s:Ellipse id="ellipse1"        
      width="100"
      height="100"
      horizontalCenter="-25"
      verticalCenter="-25">
  <s:fill>
   <s:SolidColor color="red" />
  </s:fill>
 </s:Ellipse>
 
 <s:Ellipse id="ellipse2"
      width="100"
      height="100"
      horizontalCenter="25"
      verticalCenter="-25">
  <s:fill>
   <s:SolidColor color="blue" />
  </s:fill>
 </s:Ellipse>
 <s:HGroup id="e3" width="100" height="100" horizontalCenter="0" verticalCenter="25">
  <s:Ellipse id="ellipse3"
       blendMode="{comboBox.selectedItem}"
       width="100"
       height="100"
       horizontalCenter="0"
       verticalCenter="25">
   <s:fill>
    <s:SolidColor color="green" />
   </s:fill>
  </s:Ellipse>
 </s:HGroup> 
 
 
</s:Application>
