# Basic example of drawing an image
|
|
# This example and library is meant to work with Adafruit CircuitPython API.
|
|
#
|
|
# This example is for use on (Linux) computers that are using CPython with
|
|
# Adafruit Blinka to support CircuitPython libraries. CircuitPython does
|
|
# not support PIL/pillow (python imaging library)!
