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

I fount this code off of the PIL API(here is the link:

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

CodePudding user response：

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")
