PIL：我可以有多种大小的相同字体的文本吗？ （Python）

Question

Currently trying to have the same font for an image with PIL but with different sizes.

Tried to have two different font instances but it didn't work. How can I do that?

Answer 1

If you're using ImageFont.truetype() , you'll need multiple instances for multiple sizes.

You could neatly wrap this using functools.lru_cache() so a single font/size gets loaded only once during your app:

from functools import lru_cache

get_font = lru_cache()(ImageFont.truetype)

draw.text((10, 10), "hello", font=get_font("Arial.ttf", 10))
draw.text((10, 50), "world", font=get_font("Arial.ttf", 50))

Answer 2

I think you mean this:

#!/usr/bin/env python3

from PIL  import Image, ImageFont, ImageDraw

# Create a black canvas
canvas = Image.new('RGB', (400,200))

# Get a drawing context
draw = ImageDraw.Draw(canvas)
monospace20 = ImageFont.truetype("/Library/Fonts/Andale Mono.ttf",20)
monospace50 = ImageFont.truetype("/Library/Fonts/Andale Mono.ttf",50)

draw.text((10, 10), "Hello 20", font=monospace20, fill=(255,255,255))
draw.text((10, 90), "Hello 50", font=monospace50, fill=(255,255,255))

canvas.save('result.png')
