[]Tween.to时添加滤镜

public class CustomBitmap extends Sprite

{

    public function CustomBitmap()

    {

    }

    

    public get luminance():Number

    {

        //返回亮度参数值

        //...

    }

    //亮度,其他一样

    public set luminance(value:Number):void

    {

        //你自己的处理代码

        //...

    }

}



var displayObj:CustomBitmap = new CustomBitmap();

Tween.to(displayObj,{luminance:1.2},300);
