Hi ,I'm new to OpenCV. Is there other methods to draw a image in MFC application using OpenCV 2.3.1? CvvImage was a highgui class that was removed from OpenCV from ver. 2.2 ,so I don't want to use it.It will be better if you mail me a simple project. Thank You! My Email: andy_young03@yahoo.cn

I find a way to solve it using GDI+. Mat m_src; Here is the implement: Gdiplus::Bitmap bitmap(m_src.cols, m_src.rows, m_src.cols * m_src.channels(),
PixelFormat24bppRGB, (BYTE*)m_src.data); Gdiplus::Graphics graphics(pDC->GetSafeHdc()); graphics.DrawImage(&bitmap, 0, 0);

But there is a problem whit this way! When the width of the image is not the multiple of 4 the gdi+ will show nothing at all; is there any way that don't need byte alliment?
