# (This is an example similar to an example from the Adafruit fork
|
||
|
|
# to show the similarities. Most important difference currently is, that
|
||
|
|
# this library wants RGB mode.)

|

|

|
|
# A more complex RGBMatrix example works with the Python Imaging Library,
|
||
|
|
# demonstrating a few graphics primitives and image loading.
|
||
|
|
# Note that PIL graphics do not have an immediate effect on the display --
|
||
|
|
# image is drawn into a separate buffer, which is then copied to the matrix
|
||
|
|
# using the SetImage() function (see examples below).
|
||
|
|
# Requires rgbmatrix.so present in the same directory.
