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))

Exactly. This is as much a virus as the program I wrote as a first year CS student that rebooted the computer due to a bad pointer dereference was a virus. (That one would probably just segfault today, but I started back in the DOS dark ages . . .)
