[matplotlib-devel] Path length in the cairo backend

[Michiel de H. <mjl...@ya...>]

Dear all,

The draw_path method in backend_cairo.py starts with a check for the number of vertices in the path, and raises an error if the path contains more than 18980 vertices:

     def draw_path(self, gc, path, transform, rgbFace=None):
         if len(path.vertices) > 18980:
             raise ValueError("The Cairo backend can not draw paths longer than 18980 points.")

This was needed in the past when cairo version 1.4.10 / pycairo version 1.4.0 would segfault:

However, we're now at cairo, pycairo version 1.8.8, and I haven't seen any segfaults after removing this check.

Does anybody object if I remove this check from the code?
