The available antialias settings for drawing shapes and text are documented here <http://cairographics.org/manual/cairo-cairo-t.html#cairo-antialias-t>.

These “children” who aren’t getting the results they expect won’t like being lied to. -- cairo mailing list [email protected] https://lists.cairographics.org/mailman/listinfo/cairo
