MSS stands for Multiple ScreenShots.

mss is an ultra-fast cross-platform multiple screenshots module in pure Python
using ctypes.

Featues:
* Python 3.9+, PEP8 compliant, no dependency, thread-safe
* very basic, it will grab one screenshot by monitor or a screenshot of all
  monitors and save it to a PNG file
* you can use PIL and benefit from all its formats (or add yours directly)
* integrate well with Numpy and OpenCV
* it could be easily embedded into games and other software which require fast
  and platform optimized methods to grab screenshots (like AI, Computer Vision)
