ImageGrab alternative in linux

Question

I am following this tutorial which interacts with the screen but is done for Windows OS since ImageGrab is not available in linux

import numpy as np
from PIL import ImageGrab
import cv2
import time

def screen_record():
    last_time = time.time()
    while(True):
        # 800x600 windowed mode
        printscreen =  np.array(ImageGrab.grab(bbox=(0,40,800,640)))
        print('loop took {} seconds'.format(time.time()-last_time))
        last_time = time.time()
        cv2.imshow('window',cv2.cvtColor(printscreen, cv2.COLOR_BGR2RGB))
        if cv2.waitKey(25) & 0xFF == ord('q'):
            cv2.destroyAllWindows()
            break

Is there any alternative for ImageGrab or is better to switch OS?

Does pb.get_from_drawable(w,w.get_colormap(),0,0,0,0,sz[0],sz[1]) give the same output that ImageGrab? — lapinkoira, Apr 20 '17 at 13:27
No, that gives you a GdkPixbuf. It's easy to convert it to a numpy array though. — Aran-Fey, Apr 20 '17 at 13:28

Use the pyscreenshot library. It's the ImageGrab replacement for linux systems.

import pyscreenshot as ImageGrab
im = ImageGrab.grab()
im2 = np.asanyarray(im)

Hope this will work fine for your code.

Yes but before you need to do .....pip install pyscreenshot....on your terminal – vishwampandya Nov 10 '21 at 11:50
Ubuntu 22 has a problem, it grabs, yes, but shows a window to allow to share the image with the script... – jaromrax Jul 02 '23 at 14:47
