Basic Python-Fu usage
#1
I queried Bing's Co-Pilot what tool and what code might serve to automate splitting an image into squares, this to conform to the format requirement of a cloud-based machine vision tool called Roboflow, which I'm intending to use to automate crack detection in concrete. (I've managed to learn enough about labelling in CVAT to download a json file containing the annotations in COCO 1.0, but am stuck attempting to train a model locally on my PC using detectron2.) To stay in motion while I await help on that, here's where I'm stuck using a Python-Fu script in Gimp.

When the code from Co-Pilot didn't produce anything, I asked it to simplify the operation to first confirm basic functionality using scripting in Gimp. It suggested creating a new file, but when that didn't produce anything, it further simplified to create a simple message, "Hello from Python-Fu". And when that only flashed the Console for a fraction of a sec, it included a prompt to pause for 10 seconds, which then at least that pause did work. That said, I'm not even seeing the pause when adding the create new image prompt:

from gimpfu import *

import time

def simple_message(image, drawable):
    gimp.message("Hello from Python-Fu!")
    time.sleep(10)  # Pause for 10 seconds

def create_image(image, drawable):
    save_dir = "D:/ALDOT_Model/Split_Test"  # Change this to your desired directory
    os.makedirs(save_dir, exist_ok=True)

    # Create a new image
    new_image = pdb.gimp_image_new(100, 100, RGB)
    new_layer = pdb.gimp_layer_new(new_image, 100, 100, RGB_IMAGE, "New Layer", 100, NORMAL_MODE)
    pdb.gimp_image_insert_layer(new_image, new_layer, None, -1)
    pdb.gimp_image_flatten(new_image)
    pdb.file_png_save(new_image, pdb.gimp_image_get_active_drawable(new_image), os.path.join(save_dir, "new_image.png"), "new_image.png", False, 9, True, True, True, True, True)
    gimp.message("Created and saved a new image as new_image.png")

register(
    "python_fu_create_image",
    "Create a new image and save it",
    "Create a new image and save it",
    "Your Name",
    "Your Name",
    "2024",
    "<Image>/Python-Fu/Create Image",
    "*",
    [],
    [],
    create_image)

main()

Many thanks for your insights!
