Take screenshot of second monitor with python on OSX

Take screenshot of second monitor with python on OSX

2024/10/14 21:19:25

I am trying to make an ambient light system with Python. I have gotten pyscreenshot to save a screenshot correctly, but I can't figure out how to get it to screenshot my second monitor (if this is even possible).

Is there a way to take a screenshot of my second monitor in Python using pyscreenshot (or something else)? I am using OSX Yosemite if that makes any difference.

Answer

Use the built-in screencapture command and pass it 2 filenames. I believe it lives in /usr/sbin/screencapture so the command will look like this:

/usr/sbin/screencapture screen1.png screen2.png

I assume you know how to shell out to it using the subprocess module, along these lines

from subprocess import call
call(["/usr/sbin/screencapture", "screen1.png", "screen2.png"])
