C# WPF项目实战(经典)
目的：输出两台摄像头图像和两路设备图像，每一路设备截图6张主要知识：
1. 通过SDK调取摄像头图像，并对图像进行剪裁；
2. WPF中定时器DispatcherTimer用法；
3. WPF中跨线程访问控件方法
Dispatcher.Invoke((Action)delegate {}）；
区别于winform中
this.Invoke((Action)delegate {}）；
4.xml操作：
XmlDocument xmlDoc = new XmlDocument();
xmlDoc.Load(AppDomain.CurrentDomain.BaseDirectory + "\\config.xml");
XmlNode settingNode = xmlDoc.DocumentElement;
XmlElement e = settingNode.SelectSingleNode("DeviceType") as XmlElement;
if (e == null)
{
deviceType = "tps2000";
}
else
{
deviceType = e.InnerText;
}
5. 带多个参数的委托
DP1 = new DataProcess(DeviceIP1, LocalPort1,0);
DP1.ShowEvent1 = DrawControls1;
DP1.Start();//启动线程
6.多线程操作
Thread t1 = new Thread(new ThreadStart(DataRevThread)); //开启DataRevThread
t1.Name = "DataRevThread"; //线程名字
t1.Start();
t1.IsBackground = true; //后台运行
7. UDP接收，解码；
8. emgucv使用；
9. 工厂模式：
ModelFactory MF = new ModelFactory();
DM = MF.CreateDataModelFactory_v1(sNeed.ToString());
10.信号量线程间同步
Semaphore TaskSemaphoreData = new Semaphore(0, 2560); //数据缓存队列缓存区
TaskSemaphoreRev.WaitOne(); //等待接收队列
11.Bitmap转换为ImageSource
public static extern bool DeleteObject(IntPtr hObject);
public static ImageSource ChangeBitmapToImageSource(Bitmap bitmap)
{
IntPtr hBitmap = bitmap.GetHbitmap();
ImageSource wpfBitmap = System.Windows.Interop.Imaging.CreateBitmapSourceFromHBitmap(
hBitmap,
IntPtr.Zero,
Int32Rect.Empty,
BitmapSizeOptions.FromEmptyOptions());
if (!DeleteObject(hBitmap))
{
throw new System.ComponentModel.Win32Exception();
}
return wpfBitmap;
}
12.Queue和list的操作
包括但是不限于以上内容
