This is a simple qr code reader. It has a bounding box for each qr code it sees and scales text based on how close or far away the qr code is.
Look at my fork for pynotifier and copy the pynotifier.py file; place it into the folder named pynotifier in the location:
~\python\lib\site-packages\pynotifier\
For win10Toast, copy the _init_.py file from the fork, but instead go to:
~\python\lib\site-packages\win10toast\
