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);
}
