Zooming functionality in OpenCV imshow in Windows

✔ Recommended Answer

appears to be a longer procedure though, so you could instead switch to matplotlib's pyplot function (uses Qt). you need to apply this oneliner before (see Extracting a region from an image using slicing in Python, OpenCV for details):

import cv2import matplotlib.pyplot as pltimage = cv2.imread("~\\imagedir\\image.jpg")plt_image = cv2.cvtColor(image, cv2.COLOR_BGR2RGB)imgplot = plt.imshow(plt_image)
