Hi everybody, I believe a bug was introduced in revision 7002 of backend_cairo.py. This code, in two places, now calls RendererCairo.convert_path with two arguments (ctx and tpath), whereas RendererCairo.convert_path expects three arguments. In one other place, RendererCairo.convert_path is called (correctly) with three arguments. One example of the code containing the bug is
tpath, affine = clippath.get_transformed_path_and_affine() ctx.new_path() affine = affine + Affine2D().scale(1.0, -1.0).translate(0.0, self.height) tpath = affine.transform_path(tpath) RendererCairo.convert_path(ctx, tpath) Before this revision, the corresponding code was tpath, affine = path.get_transformed_path_and_affine() ctx.new_path() affine = affine + Affine2D().scale(1.0, -1.0).translate(0.0, self.renderer.height) RendererCairo.convert_path(ctx, path, affine) RendererCairo.convert_path is defined as @staticmethod def convert_path(ctx, path, transform): so with three arguments. Either the calls to convert_path are incorrect, or convert_path should be updated to handle two arguments. --Michiel ------------------------------------------------------------------------------ Register Now & Save for Velocity, the Web Performance & Operations Conference from O'Reilly Media.
