Create a blank PNG image with a test string—A code written by ChatGPT o3-mini-high.
This script is created by ChatGPT o3-mini-high with the following prompt:

    Objective: Write a Python code that creates a PNG file.
    Specification:
    - Ask the user for the dimension of the image.
    - Ask the user for a test string to display in the center of the image.
    - Python 3.12.2 compatible.
    - Pillow 10.2.0 compatible.
    
    Changes made by ChatGPT o3-mini-high:
    - Replaced draw.textsize() with draw.textbbox() to calculate the text dimensions 
      in Pillow 10.2.0.
    - The bounding box coordinates (bbox) are used to calculate the width and height 
      of the text, which helps center it properly.
    This should work without any errors in Pillow 10.2.0 and Python 3.12.2.

# Ask the user for the image dimensions

# Ask the user for the test string to display in the center of the image
text = input("Enter the text to display in the center of the image: ")

# Create a new image with the specified dimensions and a white background
image = Image.new("RGB", (width, height), "white")

# Initialize ImageDraw to draw on the image
draw = ImageDraw.Draw(image)

# Try to load a basic font; if unavailable, fall back to a default one
try:
    font = ImageFont.truetype("arial.ttf", 40)

# Calculate the bounding box of the text to center it
bbox = draw.textbbox((0, 0), text, font=font)
text_width = bbox[2] - bbox[0]
text_height = bbox[3] - bbox[1]

# Calculate the position to center the text
x_position = (width - text_width) // 2
y_position = (height - text_height) // 2

# Draw the text in the center of the image
draw.text((x_position, y_position), text, font=font, fill="black")

# Save the image to a PNG file
image.save("test_image.png")

print("Image created and saved as 'test_image.png'.")
