鼠標滑過產生水紋，效果圖如下：

XMAL就放置了一個img標簽

?

後臺主要代碼

窗體加載：

private void Window_Loaded(object sender, RoutedEventArgs e) { Bitmap bmp = Properties.Resources.water; ww = new WaterWave(bmp); //設置顯示大小和圖片一樣 this.gInfo.Width = bmp.Width; this.gInfo.Height = bmp.Height; this.imgShow.Source = ToConvertToImageSource(bmp); ToBindTimerEvent(); }

?

計時器：

public void ToBindTimerEvent() { //創建timer 計時器 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); }

?

鼠標移動事件：

?

private void Image_MouseMove(object sender, MouseEventArgs e) { //獲取表示二維空間內的 X 和 Y 坐標對，X、Y 為 double 類型 System.Windows.Point position = e.GetPosition(this); //轉換為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); }
