Open high resolution images with Opencv

问题

I can't open a 24MP pictures on Python with opencv. It only opens the upper left part apparently and not the full image. The kernel also stops after running the code.

Here's my code: import cv2 import numpy as np

PICTURE_PATH_NAME = "IMG.JPG"
img = cv2.imread(PICTURE_PATH_NAME)
gray = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)

cv2.imshow("Gray Image", gray)
cv2.waitKey(0)

See the documentation for imshow as to how to get it to scale your image to fit the window at https://docs.opencv.org/4.1.1/d7/dfc/group__highgui.html#ga453d42fe4cb60e5723281a89973ee563

"If you need to show an image that is bigger than the screen resolution, you will need to call namedWindow("", WINDOW_NORMAL) before the imshow."
