bool is_empty() const
This function is a boolean test to see if the path is empty, meaning containing no line segments.
bool has_currentpoint() const
This function is a boolean test checking to see if the path has a current point defined.
void ensure_space(int space)
This function ensures that enough space for space points is allocated at the end of the path.
void finish()
Trims dynamic point array to exact length of path.
Glib::RefPtr< PathDef > close_all()
