X Title: Support TTC fonts by converting them to TTF in font cache by sauerburger · Pull Request #23293 · matplotlib/matplotlib

Description: PR Summary This PR adds support for all ttf fonts bundeled in ttc files. In FontManager.addfont(), if a font ends in .ttc, the new functions _read_ttc() and _dump_ttf() are triggered to extract all TTF fonts from the collection. The extracted fonts are stored in the font cache directory with the .ttf extension and added to the list of ttf fonts. The details of the implantation can be changed (for example where to put the parsing code). Do you think the overall strategy of parsing TTC, dumping TTF to the font cache is a good idea? Why is it useful Solves #12830 Solves #3135 Adds support for something like Helvetica bold+italic on a mac On my mac, only 10 system font families are in TTF format, while there are 26 font collections in TTC format. Caveats If users upgrade to a version that includes this change, it will only become effective once the font cache is rebuilt. PR Checklist Tests and Styling Has pytest style unit tests (and pytest passes). Is Flake 8 compliant (install flake8-docstrings and run flake8 --docstring-convention=all). Documentation New features are documented, with examples if plot related. New features have an entry in doc/users/next_whats_new/ (follow instructions in README.rst there). [N/A] API changes documented in doc/api/next_api_changes/ (follow instructions in README.rst there). [N/A] Documentation is sphinx and numpydoc compliant (the docs should build without error).
