WPF 实现水纹效果

原文: WPF 实现水纹效果

鼠标滑过产生水纹，效果图如下：

XMAL就放置了一个img标签

后台主要代码

窗体加载：

private void Window_Loaded(object sender, RoutedEventArgs e) { Bitmap bmp = Properties.Resources.water; ww = new WaterWave(bmp); //设置显示大小和图片一样 this.gInfo.Width = bmp.Width; this.gInfo.Height = bmp.Height; this.imgShow.Source = ToConvertToImageSource(bmp); ToBindTimerEvent(); }

计时器：

public void ToBindTimerEvent() { //创建timer 计时器 DispatcherTimer timer = new DispatcherTimer { Interval = new TimeSpan(0, 0, 0, 0, 100) }; timer.Tick += new EventHandler(timer_Tick); timer.Start(); } public void timer_Tick(object sender, EventArgs e) { Bitmap b = ww.GetFrame(); this.imgShow.Source = ToConvertToImageSource(b); }

鼠标移动事件：

private void Image_MouseMove(object sender, MouseEventArgs e) { //获取表示二维空间内的 X 和 Y 坐标对，X、Y 为 double 类型 System.Windows.Point position = e.GetPosition(this); //转换为System.Drawing.Point形式 System.Drawing.Point dPoint = new System.Drawing.Point(); dPoint.X = (int)position.X; dPoint.Y = (int)position.Y; ww.DropStone(dPoint); }
