In order to create a recipe with cross-platform support, we have elected to use the pyscreenshot module. This module relies on a few dependencies, specifically the Python Imaging Library (PIL), and one or more backends. The backend used here is the WX GUI library. All three of these modules can be installed with pip:
pip install pyscreenshot==0.4.2 pip install Pillow==4.2.1 pip install wxpython==4.0.0b1
To learn more about the pyscreenshot library, visit https://pypi.python.org/pypi/pyscreenshot.
All other libraries used in this script are present in Python's standard library.
