MFC嵌套OpenCV窗口并显示图片

1.图片适应PIC conrol大小

g_SrcImage = imread(fileDict[0]); //加载图片
    
        CRect rect;
        m_pic.GetWindowRect(rect); //获取picture control控件变量的rect
        namedWindow(WINDOW_NAME,CV_WINDOW_NORMAL);//可以改变窗口大小
        resizeWindow(WINDOW_NAME, rect.Width(), rect.Height());//根据piccontrol的大下设置opencv窗口的大小
    
        HWND hWnd = (HWND)cvGetWindowHandle(WINDOW_NAME);//嵌套opencv窗口
        HWND hParent = ::GetParent(hWnd);
        ::SetParent(hWnd, GetDlgItem(IDC_PIC)->m_hWnd);
        ::ShowWindow(hParent, SW_HIDE);
    
        imshow(WINDOW_NAME, g_SrcImage);//将图片显示在opencv窗口上，会强制改变图片原始比例

2.PIC Control大小适应图片

1     namedWindow(WINDOW_NAME);//创建OpenCV窗口    
     2     HWND hWnd = (HWND)cvGetWindowHandle(WINDOW_NAME);//嵌套opencv窗口
     3     HWND hParent = ::GetParent(hWnd);
     4     ::SetParent(hWnd, GetDlgItem(IDC_PIC)->m_hWnd);
     5     ::ShowWindow(hParent, SW_HIDE);
     6 
     7     
     8     g_SrcImage = imread(fileDict[0]); //加载图片
     9 
    10     CWnd* pWnd1 = GetDlgItem(IDD_SEG_DIALOG); //获取主窗口句柄
    11     
    12     int x = GetSystemMetrics(SM_CXSCREEN) / 2 - g_SrcImage.cols / 2; //使mfc窗口居中显示，获取对应于屏幕的左上角点
    13     int y = GetSystemMetrics(SM_CYSCREEN) / 2 - g_SrcImage.rows / 2;
    14 
    15     SetWindowPos(pWnd1, x, y, g_SrcImage.cols + 180, g_SrcImage.rows + 65, SWP_SHOWWINDOW); //根据图片大小，设置mfc窗口位置和大小
    16     m_pic.MoveWindow(150, 10, g_SrcImage.cols, g_SrcImage.rows); //根据图片大小，设置piccontrol大小
    17     
    18     imshow(WINDOW_NAME, g_SrcImage);//opencv显示图片
    19     waitKey(20);
