在 pyautogui 中保存热键截图

Question

I have taken a screenshot using hotkeys in pyautogui, as that way I was able to get only the window content. Now I don't seem to be able to save it. Am I doing something wrong or is there any way to get the screenshot?

screenshot = pyautogui.hotkey('alt', 'printscreen')
screenshot.save('temp.jpg')

Answer 1

Exspression pyautogui.hotkey('alt', 'printscreen') retuns nothing, so you can't save image from it.

Simplest solution I could find is to install some extra modules:

pip install pillow keyboard

Module keyboard is used to create smarter hotkey with python function as callback.

Such function shoul press Print Screen to save image to clipboard, then we can get image from clipboard with PIL module and save it to file.

Here is the example:

import time

import pyautogui
import keyboard

from PIL import ImageGrab

def save_screenshoot():
    pyautogui.press('printscreen')
    im = ImageGrab.grabclipboard()
    im.save('screenshoot.png','PNG')

keyboard.add_hotkey('alt', save_screenshoot)

while True:
    # While this loop is active 'alt' wil save screenshoot
    time.sleep(5)
