关于WPF里的一些Effect效果..

Microsoft.Expression.Media.Effects 效果都在这里,

包括 光晕,放大,素描,水纹,等各种效果,    可以应用在 UIelement上...

 Microsoft.Expression.Media.Effects.RippleEffect be = new Microsoft.Expression.Media.Effects.RippleEffect();
        void MainWindow_Loaded(object sender, RoutedEventArgs e)
        {
            //be.BaseIntensity = 2;
            CompositionTarget.Rendering += new EventHandler(CompositionTarget_Rendering);
            be.Phase = 0.5;
            //be.Frequency = 2000;
            //be.InnerRadius = 0.2;
            //be.OuterRadius = 0.2;
            be.Center = new Point(0, 0.5);

            img.Effect = be;
        }

        void CompositionTarget_Rendering(object sender, EventArgs e)
        {
            Point p = be.Center;
            if (p.X > 1.5)
            {
                p.X = -0.5;
            }
            be.Center = new Point(p.X + 0.005, p.Y);
        }
