render_maxio.py

#!/usr/bin/python3

# This method uses the third-party maxio renderer to render reMarkable documents locally on the computer.
# It downloads the raw reMarkable files to the computer and renders them locally.
#
# It requires maxio and SSH access to the reMarkable (to download the raw files), but no USB connection.
#
# As of 2017-02-14, it produces worse results than the official reMarkable renderer.
# It fails in some cases, particularly for highlighted documents of the new v3 format.
# It was tested using this fork of maxio, paired with this fork of rmscene (for parsing v3 formatted documents):
# * https://github.com/hersle/maxio/tree/overlay
# * https://github.com/hersle/rmscene/tree/anysize
#
# To use a different third-party renderer, wrap it in a script with call signature like this one!
