opencv笔记1---如何把opencv窗口镶嵌到MFC窗口

1.直接将opencv的imshow窗口镶嵌到MFC窗口内:

namedWindow("view", WINDOW_AUTOSIZE);  

HWND hWnd = (HWND)cvGetWindowHandle("view");  

HWND hParent = ::GetParent(hWnd);  

::SetParent(hWnd, GetDlgItem(face_picture)->m_hWnd);  

::ShowWindow(hParent, SW_HIDE);//隐藏运行程序框

2.将图片用HDC绘画

1.   Mat frame=imread("d:/1.jpg")
2.     CDC* pDC = GetDlgItem(IDC_ShowImage)->GetDC();  
3.     HDC hDC = pDC->GetSafeHdc();  
4.     IplImage img = frame;  
5.     CvvImage cimg;  
6.     cimg.CopyOf(&img);  
7.     CRect rect;  
8.     GetDlgItem(IDC_ShowImage)->GetClientRect(&rect);  
9.     cimg.DrawToHDC(hDC, &rect);  
10.     ReleaseDC(pDC);
