在Linux中的ImageGrab替代品

Question

我正在关注本教程,该教程与屏幕交互但是为Windows操作系统完成,因为在Google中没有ImageGrab

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

是否有ImageGrab的替代方案或更好的切换操作系统？

Answer 1

使用pyscreenshot库.这是用于Linux系统的ImageGrab替代品.

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

希望这对你的代码很好.
