If CvvImage
was a highgui
class that was removed from OpenCV from ver. 2.2.
It has 2 methods relevant to drawing in a Win32/MFC application.
#if defined WIN32 || defined _WIN32
/* draw part of image to the specified DC */
virtual void Show( HDC dc, int x, int y, int width, int height,
int from_x = 0, int from_y = 0 );
/* draw the current image ROI to the specified rectangle of the destination DC */
virtual void DrawToHDC( HDC hDCDst, RECT* pDstRect );
#endif
Unfortunately, if you don't use HighGui, the HighGui windows, then after you need to grab the frame and frame you'll have to display it yourself using the Windows APIs (e.g. Win32 or MFC).MFC).
Some relevant Win32/MFC functions to do this are ::SetDIBitsToDevice
or ::StretchDIBits
.
