cairo:path-data-to-list (path)

path -- a cairo:path-t instance

The list with the path.

Creates a list with the path information from a cairo:path-t instance. See the cairo:copy-path and cairo:copy-path-flat functions. There is no Lisp API exported that gives direct access to the internal path data, nor has the Lisp API functions to create from scratch path data information.
