OPENCV Desktop Capture

Question

How to capture the desktop in OpenCV (ie. turn a bitmap into a Mat)?

Hello,

Can anyone explain to me how I would use this code in OpenCV to capture the deskt

Answer 1

It seems you forgot to capture the return of hwnd2mat():

HWND hwndDesktop = GetDesktopWindow();
Mat src = hwnd2mat(hwndDesktop);
imshow("output", src);
waitKey(0);
