ImageGrab.grab(bbox()) 不返回 RGB 值

Question

This is my code:

import pyscreenshot as ImageGrab


class Main:
    px = ImageGrab.grab(bbox=[799, 449, 800, 450]).load()

However, when I print px[0, 0] it returns me just an int, not an RGB triplet. Anyone knows why that is?

Answer 1

Does this code work for you (you will need to install MSS first):

import mss

with mss.mss() as sct:
    img = sct.grab((799, 449, 800, 450))
    print(img.pixel(0, 0))

In my terminal:

$ python3 test.py

Answer 2

executing the following works for me

import pyscreenshot as ImageGrab

def main():
    px = ImageGrab.grab(bbox=[799, 449, 800, 450]).load()
    print(px[0, 0]);

main()

in the terminal

$ python3 test.py
