# Cura 5.4 JPEG Thumbnail creator
#
# This script has been changed for E3S1PROFORKBYTT by Thomas Toka.
#
# Intruduced with v008 into E3S1PROFORKBYTT.
#
# It is based on the modification of:
#
# Professional firmware for Ender3v2
# Miguel A. Risco-Castillo
# version: 1.4
# date: 2022-05-18
#
# Contains code from:
# https://github.com/Ultimaker/Cura/blob/master/plugins/PostProcessingPlugin/scripts/CreateThumbnail.py
