Edit

  • Jan 02, 2021 – Initial commit.

  • Jan 05, 2023 – Adapt myimagelib import style.

  • Feb 08, 2023 – Rewrite in function wrapper form, to make autodoc work properly. (autodoc import the script and execute it, so anything outside if __name__=="__main__" will be executed, causing problems)
