Simple Custom Hot Folder

Simple one-line edits to the script below can automate a great variety of scaling, rotation, mirroring, and other transforms.

It would take an infinite amount of programming time to provide the variety gained simply by using this general purpose scripting language.

Small changes here can do a lot, and limited customization services are available directly from Wasatch.

# Customized hot folder in Python 3
#
# Simple edits to the 'printJob' function can be used to do things like rotate, scale, or mirror every image.
#
# A line could be added to remove the file from the suspenseFolder after it has been printed.
#
# With a bit more work, this could be modified so that images could be accumulated into layouts.
