How to split ttc to ttf

[gachiemchiep]

Hello forks.
How to use this tool to convert ttc into ttf ?
There's an online tool at https://transfonter.org/ttc-unpack that can split ttc into multiple ttf.

you can use ttx command line tool with the -y option for each sub-font in the ttc file to extract .ttx (XML) files for each of the sub-fonts, then again the ttx tool to recompile the .ttx files to individual binary font files.
Or you could use a script like this one:

from fontTools.ttLib.ttCollection import TTCollection
import os
import sys

filename = sys.argv[1]
ttc = TTCollection(filename)
basename = os.path.basename(filename)
for i, font in enumerate(ttc):
    font.save(f"{basename}#{i}.ttf")

next time please use https://github.com/fonttools/fonttools/discussions to ask questions instead of filing an issue.

Thanks @anthrotype! Just one small typo: the sys module has no attribute args, but argv. So, this worked for me:

#!/usr/bin/env python

from fontTools.ttLib.ttCollection import TTCollection
import os
import sys

filename = sys.argv[1]
ttc = TTCollection(filename)
basename = os.path.basename(filename)
for i, font in enumerate(ttc):
    font.save(f"{basename}#{i}.ttf")
