3DLDF currently includes the following classes representing plane
("Regular Closed Plane Curve"),
Reg_Cl_Plane_Curve are derived
Rectangle are derived
Circle are derived
Reg_Cl_Plane_Curve are meant to be used as base classes only, so
objects of these types should normally never be declared.
Circle all ultimately derive from
Path, they are really
just special kinds of
In particular, they inherit their drawing and filling functions from
Path, and their transformation functions take the same arguments
They also have constructors
and setting functions that work in a similar way, with a few minor
differences, to account for their different natures.
See Polygon Reference, Rectangle Reference,
Ellipse Reference, and Circle Reference, for complete
information on these classes.
