kandi X-RAY | qahirah Summary
This introduction will assume you have some knowledge of the Cairo API itself; possibly you have even used the Pycairo Python binding. Qahirah also has “Context”, “Surface” and “Pattern” classes, similar to those in Pycairo. To summarize:. (There are other object types, but understanding these three is, I think, core to understanding how Cairo works.).

QUESTION
I want to create and rasterize vector graphics in Python. I suspect that Pycairo
or cairocffi
(edit: or Qahirah
) are a great choice. (If not, comments are welcome.)
What are the practical differences between the two?
Specifically, the Pycairo
documentation says:
If Pycairo is not what you need, have a look at cairocffi, which is an API compatible package using cffi or Qahirah, which is using ctypes and provides a more "pythonic" API with less focus on matching the cairo C API.
But this raises some questions: In what cases may Pycairo be "not what you need", whereas cairocffi is? In what way are cffi/Qahirah/ctypes better than whatever Pycairo does instead? In what ways is Pycairo not "pythonic"? If cairocffi is better than Pycairo, why is Pycairo more popular, does it have advantages?
Edit: A comma might be missing after "cffi" in the quote above. In that case, it's not about "Pycairo vs. cairocffi", but about "Pycairo vs. cairocffi vs. Qahirah".
