cl-pixman is a Common Lisp wrapper for pixman written on CFFI. Pixman is a portable library for low-level pixel manipulation.
I wrote this wrapper to have an alternative to SDL2 blitting for low-level pixel operation. It directly uses CFFI pointers to avoid. Supported API is minimal (only
pixman_image_* API is partially implemented) so feel free to contribute.
It is licensed under the LLGPL.
If you are using quicklisp:
cd <your quicklisp directory>/local-projects/ git clone <me>
Then you can just
in your REPL.
You'll need a
pixman shared object accessible to your Lisp at runtime, if you are using GNU, you can use your distro package.
