grabscreen.py Python win32api

Question

是否有任何Win32gui或此代码的Linux或Mac OS等效库？在外部项目上工作，此Windows代码将帮助我抓取屏幕。Havent能够找到任何相似的库。谢谢def grab_screen(region=None):hwin = win32gui.GetDesktopWindow()if region:        left,top,x2,y2 = region        width = x2 - left + 1        height = y2 - top + 1else:    width = win32api.GetSystemMetrics(win32con.SM_CXVIRTUALSCREEN)    height = win32api.GetSystemMetrics(win32con.SM_CYVIRTUALSCREEN)    left = win32api.GetSystemMetrics(win32con.SM_XVIRTUALSCREEN)    top = win32api.GetSystemMetrics(win32con.SM_YVIRTUALSCREEN)hwindc = win32gui.GetWindowDC(hwin)srcdc = win32ui.CreateDCFromHandle(hwindc)memdc = srcdc.CreateCompatibleDC()bmp = win32ui.CreateBitmap()bmp.CreateCompatibleBitmap(srcdc, width, height)memdc.SelectObject(bmp)memdc.BitBlt((0, 0), (width, height), srcdc, (left, top), win32con.SRCCOPY)signedIntsArray = bmp.GetBitmapBits(True)img = np.fromstring(signedIntsArray, dtype='uint8')img.shape = (height,width,4)srcdc.DeleteDC()memdc.DeleteDC()win32gui.ReleaseDC(hwin, hwindc)win32gui.DeleteObject(bmp.GetHandle())return cv2.cvtColor(img, cv2.COLOR_BGRA2RGB)

Answer 1

您可以通过以下方式抓取屏幕pyautogui：

import pyautogui

image = pyautogui.screenshot('filename.png')

Answer 2

您可以这样做：)我认为Mac OS无法使用这些WiIn32gui库。相反，您可以使用枕头抓屏。屏幕大小可以更改，具体取决于所需的大小。

import cv2

import numpy as np

import pyautogui

from PIL import ImageGrab

screen_w = 1920

screen_h = 1080

while True:

    rgb = ImageGrab.grab(bbox=(0, 0, screen_w, screen_h)) 

    rgb = np.array(rgb)

    cv2.imshow('window_frame', rgb)

    if cv2.waitKey(1) & 0xFF == ord('q'):

        break
