Capturing a window in Python

Question

I'm currently looking to find a module, or code that would allow me to capture another processes window.

I've tried working with ImageGrab, however that just captures an area of the screen rather than binding to a specific process window. Since I'm working with a small monitor I can't guarantee that something won't lap over onto the captured area of the screen, so sadly the ImageGrab solution isn't good enough.

Answer 1

You can achieve this using win32gui.

from PIL import ImageGrab
import win32gui

hwnd = win32gui.FindWindow(None, r'Window_Title')
win32gui.SetForegroundWindow(hwnd)
dimensions = win32gui.GetWindowRect(hwnd)

image = ImageGrab.grab(dimensions)
image.show()

You could also move the window to a preferred position if a small screen is the problem. win32gui.MoveWindow(hwnd, 0, 0, 500, 700, True) see win32gui.MoveWindow
