Django图像处理：单词分为两行

Question

我具有用于在图像上绘制文本的python函数。文本会打断中间单词，因此1/2单词在一行上，而1/2在另一行上。我们如何确保不会发生这种情况？ 我希望整个词都换行。

下面是图片示例

这是我的代码：

from PIL import ImageFont, Image, ImageDraw
from django.contrib.auth import get_user_model
from entities.obituary.forms import ObituaryForm

User = get_user_model()

    heading_font_path = 'static/fonts/hind-regular.ttf'
    normal_font = ImageFont.truetype(normal_font_path, 18)
    normal_font2 = ImageFont.truetype(normal_font_path, 24)
    heading_font = ImageFont.truetype(heading_font_path, 30)

    obiuary_sample_model.text_color[0], obiuary_sample_model.text_color[1], obiuary_sample_model.text_color[2], 255)

在没有空余的空间时，我们如何保持一致？
