SO, it started quite nicely with a fully working program. However nearing the end… or at the end of my programming experience or asking it to program something for me, it wrote in some nasty nasty screen flickering shit. I couldn’t stop it and it quickly just froze my screen where the only option was to push the button. I tried it a second time to confirm, but this time I was able to quickly go to a different CLI window and kill that sonobabich. Here is what it came up with in case you want to try it. maybe it only screws up my computer:

import os

    original_image = cv2.imread(image_path)
    
    if original_image is None:
        print("Error: Could not read the image.")
        return

    height, width, _ = original_image.shape
    gray_image = cv2.cvtColor(original_image, cv2.COLOR_BGR2GRAY)
    steps = duration * 10  # 10 frames per second

    for i in range(steps + 1):
        # Calculate the threshold value (0 to 255)
        threshold = int((i / steps) * 255)
        
        # Create the thresholded image
        thresholded_image = np.where(gray_image < threshold, 0, 255).astype(np.uint8)

        # Resize the thresholded image to fill the window
        resized_image = cv2.resize(thresholded_image, (window_width, window_height), interpolation=cv2.INTER_LINEAR)

        # Display the thresholded image
        cv2.imshow(window_name, resized_image)

        # Wait for a short period to create the effect
