代碼如下:
   import flash.filters.ColorMatrixFilter;//導入色彩濾鏡   var matrix:Array = [ 0.5,0.5,0.082,0,0,0.5,0.5,0.082,0,0,0.5,0.5,0.082,0,0,0,0,0,1,0 ];//定義色彩數(shù)組   var colorMat:ColorMatrixFilter = new ColorMatrixFilter(matrix);//創(chuàng)建濾鏡對象   //添加鼠標事件   image_mc.addEventListener(MouseEvent.MOUSE_OVER,over);   image_mc.addEventListener(MouseEvent.MOUSE_OUT,out);   image_mc.filters = [colorMat];   function over(e:MouseEvent):void{      image_mc.filters = [];   }   function out(e:MouseEvent):void{      image_mc.filters = [colorMat];    }
