WPF实现视差效果

鼠标移动时底部图片旋转一定角度，上层字体不旋转，来实现视差效果
    private void Image_MouseMove(object sender, MouseEventArgs e)
        {
            var moveX = (e.GetPosition(this.img).X / this.img.ActualWidth - 0.5) * (-25);
            var moveY = -(e.GetPosition(this.img).Y / this.img.ActualHeight - 0.5) * (-20);
 
            DoubleAnimation da = new DoubleAnimation();
            da.Duration = new Duration(TimeSpan.FromSeconds(1));
            da.To = 10d;
            Vector3D axis = new Vector3D(moveX, moveY, 0);
            AxisAngleRotation3D aar = this.FindName("MyAxisAngleRotation3D") as AxisAngleRotation3D;
            if (aar != null)
            {
                aar.Axis = axis;
                aar.BeginAnimation(AxisAngleRotation3D.AngleProperty, da);
            }
        }
