##I've made a python script that converts the npy files saved in a folder to png with full black and full whites. It has a basic gui.

see https://github.com/jcnwholland/Npy-to-PNG.git

import tkinter as tk
from tkinter.filedialog import askdirectory
from PIL import Image
import os
import numpy as np

def set_everything_not_black_to_full_white(image):
"""Sets all pixels in an image that are not black to full white.

Args:
    image (Image): The image to modify.

Returns:
    The modified image.
"""
image = np.array(image)
image[image != 0] = 255
return Image.fromarray(image)

def convert_npy_to_png(npy_file):
"""Converts a numpy image file to a grayscale png file.

Args:
    npy_file (str): The path to the numpy image file.

Returns:
    None.
"""
image = Image.fromarray(np.array(np.load(npy_file)).astype(np.uint8)).convert("L")
image = set_everything_not_black_to_full_white(image)
image.save(npy_file.replace(".npy", ".png"))

def main():
"""The main function."""

folder_entry = tk.Entry(root)
folder_entry.pack()

# Create a button to select the folder.
select_folder_button = tk.Button(root, text="Select Folder", command=lambda: select_folder(folder_entry))

# Update the folder entry.

folder_entry.insert(0, folder)

for npy_file in npy_files:
    convert_npy_to_png(os.path.join(folder, npy_file))
