OpenCV Shows Gray Window

Question

I\'m trying to display an image using OpenCV. I have the following very basic code:

import cv2

img = cv2.imread(\'myimage.png\', 0)  # Reads a Gray-scale im         


        

Answer 1

OK, got it.

Turns out I needed to let OpenCV start handling events, it wasn't handling the WM_PAINT event. Adding cv2.waitKey() fixed this.
