用鼠标点击图片并拖动，您将看到图片缓冲放缩效果

　　Flash中制作步骤：

　　先在Flash中导入几张图片，分别转为影片元件，拖到主场景，实例名分别为pic0_mc、pic1_mc、pic2_mc……

　　在帧上写如下代码：原文链接

for (var d:Number = 0; d<=2; d++) {
this["pic"+d+"_mc"].onPress = function() {
  mx.behaviors.DepthControl.bringToFront(this);//移到最前
  startDrag(this);
  this.onEnterFrame = function() {
   this._xscale += (200-this._xscale)/4;//缓冲放大
   this._yscale += (200-this._yscale)/4;
   if (this._xscale>=200) {
    delete this.onEnterFrame;
   }
  };
};
this["pic"+d+"_mc"].onRelease = function() {
  stopDrag();
  this.onEnterFrame = function() {
   this._xscale -= (this._xscale-100)/4;//缓冲缩小
   this._yscale -= (this._yscale-100)/4;
   if (this._xscale<=100) {
    delete this.onEnterFrame;
   }
  };
};
}
