如何从python中的字体文件中获取字体名称（标题）

Question

I want to get the font name (the title present in the description of the font file) in python.

I looked at the fonttools module but could not find any way to extract the title using it.

How can I do this?

Answer 1

You can use external tools like otfinfo to extract font meta.

otfinfo reports information about the named OpenType font files.

$ otfinfo --info raleway.ttf       
Family:              Raleway Light
Subfamily:           Regular
Full name:           Raleway Light
PostScript name:     Raleway-Light
Preferred family:    Raleway
Preferred subfamily: Light

You can call it using subprocess in python and filter desired result using regular expression.

import subprocess
import re

font_file = "/home/user/raleway.ttf"
command = "otfinfo"
params = ["--info"]
result = subprocess.run([command, *params, font_file], stdout=subprocess.PIPE).stdout
font_name_re = re.compile(r"Full name:\s*(.*)")
font_name = font_name_re.findall(result.decode())
print(font_name[0])

Output: Raleway Light

Here is how you could do it with fonttools:

from fontTools import ttLib
font = ttLib.TTFont(fontPath)
fontFamilyName = font['name'].getDebugName(1)
fullName= font['name'].getDebugName(4)

The number 1, 4 are nameID. If you need anything more, read this documentation about nameID: https://docs.microsoft.com/en-us/typography/opentype/spec/name#name-ids

Here is fonttools documentation about the naming table: https://fonttools.readthedocs.io/en/latest/ttLib/tables/_n_a_m_e.html
