Use full retina resolution on OSX
Hello
Working in Xcode, Mac OS X 10.11.5, OpenCV 2.4.13
When openCV shows an image on my MacBook Pro with retina display:
namedWindow( wndName, CV_WINDOW_NORMAL );
imshow( wndName, img );
it seems to assume screen resolution that is half the actual resolution: image size of the screen is shown twice as big, whereas image half the screen pixel size fits the screen perfectly.
Is there a way to use the real display resolution?
Thanks
I also want to display OpenCV images at full resolution of my Apple “Retina” display. Otherwise they are much too large on the screen, or I have to throw away half my resolution. It is disappointing this question received zero answers in four years.
I'm using OpenCV 4.1.2 on macOS Catalina 10.15.2 with Xcode/clang/c++
Please ask a new queston. Question is too old
