 1、控件缩放，可直接调用。需要将控件的名称，缩放的位数，时间等参数传进去。

        /// <summary>
        /// 控件绕中心缩放动画
        /// </summary>
        /// <param name="element">控件名</param>
        /// <param name="Sizefrom">开始大小</param>
        /// <param name="Sizeto">结束大小</param>
        /// <param name="power">过渡强度</param>
        /// <param name="time">持续时间，例如3秒： TimeSpan(0,0,3) </param>
        public void ScaleEasingAnimationShow(UIElement element, double Sizefrom, double Sizeto, int power, TimeSpan time)
        {
            ScaleTransform scale = new ScaleTransform();  //旋转
            element.RenderTransform = scale;
            //定义圆心位置
            element.RenderTransformOrigin = new System.Windows.Point(0.5, 0.5);
            //定义过渡动画,power为过度的强度
            EasingFunctionBase easeFunction = new PowerEase()
            {
                EasingMode = EasingMode.EaseInOut,
                Power = power
            };

            DoubleAnimation scaleAnimation = new DoubleAnimation()
            {
                From = Sizefrom,                                   //起始值
                To = Sizeto,                                     //结束值
                FillBehavior = FillBehavior.HoldEnd,
                Duration = time,                                 //动画播放时间
            };
            scale.BeginAnimation(ScaleTransform.ScaleXProperty, scaleAnimation);
            scale.BeginAnimation(ScaleTransform.ScaleYProperty, scaleAnimation);
        }
