有没有办法用ctypes在python中捕获屏幕图像？ [英] Is there a way to capture an image of the screen in python with ctypes?

问题描述

我想让python将整个屏幕的图像文件另存为带有ctypes的变量，以便我可以在程序中访问屏幕并对其进行处理（例如将其放在pygame窗口中）。我无法使用任何其他库，除非它们包含在python中（没有安装或pip）。有人知道怎么做吗？

I want to have python save an image file of the whole screen as a variable with ctypes so that I could access the screen in a program and do something with it (like put it on a pygame window). I can't use any other libraries unless they are included with python (no installing or pip). Does anyone know how to do this?

编辑：我正在使用Windows 10。

推荐答案

PIL.ImageGrab 来自PILLOW（可通过pip安装的python图像库fork）。您可以给定边界框或捕获整个屏幕。

PIL.ImageGrab is from PILLOW (a python image library fork which you can install with pip). You can give a bounding box or capture the entire screen.

更新： OP现在提到他不能使用外部库。

Update: OP now mentions he can't use external libraries.

然后，您可以实际上已打到打印屏幕和阅读剪贴板。 PILLOW的代码是开源的，随时可以使用。

Then you could virtually hit printscreen and read the clipboard. The code of PILLOW is open-source feel free to use it.

请记住，您始终可以从python内部调用命令：

>>> import os
>>> os.system("pip install pillow")

或下载该库的zip并将其导入您的代码。

Or download the zip of the library and import it in your code.
