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
import cv2
import numpy as np
import time
import tkinter as tk
from tkinter import messagebox, filedialog

def threshold_to_black(image_path, duration):
    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
        time.sleep(0.1)

        if cv2.waitKey(1) & 0xFF == ord('q'):
            break

    # Display the final black image
    cv2.imshow(window_name, np.zeros_like(thresholded_image))

It doesn't give anyone access to your system or forward information from your system to outsiders, so no.

Trojan is any malware that pretends to be a legit program. It does not need to have backdoor or info stealing capability even though most malware (trojan or not) today does. For example, pre-Internet trojans might just invisibly install themselves along the actual program they were bundled with and then nuke the system on a certain date. Antivirus companies would even advance the date on their systems in hopes of detecting these and being the first to develop a patch.

But since this program is not malicious, it just straight up hogs system resources and/or crashes it due to a mistake, it cannot be considered malware and therefore not a trojan.

Certain Intel processors from around 2000 would crash everything when loading the 4 bytes F0 0F C7 C8 into a specific register. Would you consider this a backdoor because it allows any program to crash the system? I wouldn't say so, crashing Windows 98 was probably not too hard anyway...
