FLEX对整个截屏或单个UI进行截图http://snowyrock.spaces.live.com/blog/cns!b8cbeb7169880b1d!447.entry 虽然FLEX 3.0已经自带了截图的类,但是FLEX 2.0本身就可以简单的做出来截图功能,而且也是很简单的,下面粘出来给大家秀一下. <?xml version="1.0" encoding="utf-8"?>
<mx:Application

layout="absolute">
<mx:Script>
  <![CDATA[
  import mx.core.UIComponent;
  private function captureFullScreen() : void    //截屏
  {
    var bd : BitmapData = getBitmapData( UIComponent( mx.core.Application.application ) );
    targetImage.source = new Bitmap( bd );
  }
  private function captureHiddenDatagrid() : void  //截单个UI
  {
    var bd : BitmapData = getBitmapData( UIComponent( hiddenDg ) );
    targetImage.source = new Bitmap( bd );
  }    private function getBitmapData( target : UIComponent ) : BitmapData  //截图功能函数  {
    var bd : BitmapData = new BitmapData( target.width, target.height );
    var m : Matrix = new Matrix();
    bd.draw( target, m );
