推荐答案

首先安装Python Imaging Library (pip install Pillow)

First install Python Imaging Library (pip install Pillow)

注意:您可能需要更改字体文件font_fname 的路径.

Note: you may need to change the path to your font file font_fname.

import numpy as np
import PIL
import PIL.Image as Image
import PIL.ImageDraw as ImageDraw
import PIL.ImageFont as ImageFont

font_fname = '/usr/share/fonts/truetype/freefont/FreeSansBold.ttf'
font_size = 200
font = ImageFont.truetype(font_fname, font_size)

h, w = 1080, 1920
bg_colour = (255, 255, 255)
bg_image = np.dot(np.ones((h,w,3), dtype='uint8'), np.diag(np.asarray((bg_colour), dtype='uint8')))
image0 = Image.fromarray(bg_image)
draw = ImageDraw.Draw(image0)
draw.text((530, 160), "hello world", font=font, fill='rgb(0, 0, 0)')
image0.save('hello_world.jpg')
