How do I Anchor Text and Shrink it to fit it on an Image

Question

I fount this code off of the PIL API(here is the link: https://pillow.readthedocs.io/en/stable/handbook/text-anchors.html) and I wanted to also shrink it depending on the size of the text while it is centered.

here is the anchoring code

from PIL import Image, ImageDraw, ImageFont

font = ImageFont.truetype("mont.ttf", 48)
im = Image.new("RGB", (200, 200), "white")
d = ImageDraw.Draw(im)
d.text((100, 100), "Quick", fill="black", anchor="ms", font=font)
im.save('text.png')

And the outcome looks like this:

But if you increase the word size it looks like this:

So I just want the text to be centered and shrunk to fit the image

No detail about the requirements, so here only for result image with fixed size (200, 200), so font size will be changed.

• Find the size of text by ImageDraw.textsize
• Draw on an image with same width as the text by ImageDraw.text
• Resize image to (200-2*border, 200-2*border) by Image.resize
• Paste the resized image to a 200x200 image by Image.paste

from PIL import Image, ImageDraw, ImageFont

def text_to_image(text, filename='text.png', border=20):
    im = Image.new("RGB", (1, 1), "white")
    font = ImageFont.truetype("calibri.ttf", 48)
    draw = ImageDraw.Draw(im)
    size = draw.textsize(text, font=font)
    width = max(size)
    im = Image.new("RGB", (width, width), "white")
    draw = ImageDraw.Draw(im)
    draw.text((width//2, width//2), text, anchor='mm', fill="black", font=font)
    im = im.resize((200-2*border, 200-2*border), resample=Image.LANCZOS)
    new_im = Image.new("RGB", (200, 200), "white")
    new_im.paste(im, (border, border))
    new_im.show()
    # new_im.save(filename)

text_to_image("Hello World")
