动态 select 文本消息大小并写入图像文件(align = justify)

Dynamically select the Text Message Size and write in image file (align = justify)

我有一个代码可以从互联网上收集短信。消息大小从 20-500 字不等。我想在具有以下条件的图像文件中写入文本:

  1. 图像大小应根据字符串大小和书面居中对齐动态变化。
  2. 图像背景应为黑色。
  3. 测试颜色应该是随机的(从颜色列表文件中挑选)
  4. 测试字体应该是随机的(从字体列表文件中挑选)

我写了这段代码,但无法得到想要的结果。

from PIL import Image, ImageDraw, ImageFont
import textwrap

font_list = []
color_list = []

astr = 'NRB Bearing Limited has informed the Exchange regarding Pursuant to Regulation 44(3) of the Listing Regulations, we enclose herewith the following in respect of the 54th Annual General Meeting (AGM) of the Company held on Friday, August 9, 2019 at 3:30 p.m.; at the M.

para = textwrap.wrap(astr, width=100)

MAX_W, MAX_H = 1200, 600
im = Image.new('RGB', (MAX_W, MAX_H), (0, 0, 0, 0))
draw = ImageDraw.Draw(im)
font = ImageFont.truetype('C://Users//Alegreya//Alegreya-RegularItalic.ttf', 18)

current_h, pad = 100, 20
for line in para:
    w, h = draw.textsize(line, font=font)
    draw.text(((MAX_W - w) / 2, current_h), line, font=font)
    current_h += h + pad

ImageDraw.text 处理多行文本并考虑间距等

# randomly pick a font
