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 + 1

else:

    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 pyautoguiimage = 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 cv2import numpy as npimport pyautoguifrom PIL import ImageGrabscreen_w = 1920screen_h = 1080while 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
