Documentation

生成文字图片:在一定的区域,支持换行,丢弃,缩小来完成适应区域 The documentation is hosted at https://github.com/BingerYang/pyfont

Installation

pip install pyfont

Usage

example: 1. write 通过控制 limit_width, limit_count 与 传入回调返回,决定是否保留换行,或者截断丢弃

# -*- coding: utf-8 -*-
from pyfont import FontAttr, FontDraw
from PIL import Image

image = Image.new('RGBA', (int(400), int(400)), (1, 1, 1, 0))
path = 'C:\Windows\Fonts\simsun.ttc'
font = FontAttr(path=path, size=20, limit_width=220, fill_color=(1, 1, 1, 255))
# obj = FontDraw(bg=image, font=font)
obj = FontDraw(font=font)

# 通过控制 limit_width,limit_count 与 传入回调返回,决定是否换行,或者丢弃
# limit_text_cb=None 不处理(超过)
# limit_text_cb 返回值False丢弃多余,返回True(保留换行)
def limit_text_cb(index, line, state):
    print('index:', index, line[index:], state)
    return True


result = obj.write(text="我们是中国人,我爱我的祖国\n你好", limit_text_cb=limit_text_cb)
img = result.img
print(img.size)
img.show()
print(font.size, font.line_height)
  1. 通过 limit_width, limit_height 适当的缩小字体范围,以适应区域
from pyfont import FontAttr, FontDraw
from PIL import Image

image = Image.new('RGBA', (int(400), int(400)), (1, 1, 1, 0))
path = 'C:\Windows\Fonts\simsun.ttc'
font = FontAttr(path=path, size=20, limit_width=220, fill_color=(1, 1, 1, 255))
# obj = FontDraw(bg=image, font=font)
obj = FontDraw(font=font)

text="我们是中国人,我爱我的祖国\n你好"
size = obj.get_size_at_limit_range(text, font.size)
font.size = size
result = obj.write(text=text)
print(result.offset, result.lines)
img = result.img
print(img.size)
img.show()
