Question / Issue:

Below is my C Code for OpenCV to show a window. How do I keep it open, so I can screen capture it? cv::namedWindow( "img", cv::WINDOW_AUTOSIZE ); cv::imshow( "img", img ); cv::waitKey( 0 ); cv::destroyWindow( "img" );

Try the solution below and then kill the app when you're ready to close the window (e.g., Ctrl+C) cv::namedWindow( "img", cv::WINDOW_AUTOSIZE ); cv::imshow( "img", img ); cv::waitKey( 0 ); //cv::destroyWindow( "img" ); while(1) { }
