Beispiel #1

cairo_bool_t cairocks_map_path_onto(cairo_t* cr, cairo_path_t* path) {
	cairo_path_t* cur_path = 0;

	parametrized_path_t param;

	if(cairo_status(cr) || !path) return FALSE;

	cur_path = cairo_copy_path(cr);

	param.path = path;
	param.parametrization = parametrize_path(path);

	cairo_new_path(cr);

	transform_path(
		cur_path,
		(transform_point_func_t)(point_on_path),
		&param
	);

	cairo_append_path(cr, cur_path);

	free(param.parametrization);

	cairo_path_destroy(cur_path);

	return TRUE;
}
