Ellipses

Ellipse out_ellipse (void) const function
Returns the smallest Ellipse that surrounds the Rectangle. 
          Point P(-1, -1, 3);
          Rectangle r(P, 3, 4, 60, 30, 15);
          Ellipse e = r.out_ellipse();
          e.filldraw(black, gray);
          r.unfilldraw(black);

Ellipse in_ellipse (void) const function
Returns the Ellipse enclosed by the Rectangle. 
          Point P(-1, -1, 3);
          Rectangle r(P, 3, 4, 60, 30, 15);
          Ellipse e = r.in_ellipse();
          r.filldraw(black, gray);
          e.unfilldraw(black);

Ellipse draw_out_ellipse ([const Color& ddraw_color = *Colors::default_color, [string ddashed = "", [string ppen = "", [Picture& picture = current_picture]]]]) const function
Draws the smallest Ellipse that surrounds the Rectangle. The arguments are like those of Path::draw() (see Path Reference; Drawing and Filling). The return value is the surrounding Ellipse.

Ellipse draw_in_ellipse ([const Color& ddraw_color = *Colors::default_color, [string ddashed = "", [string ppen = "", [Picture& picture = current_picture]]]]) const function
Draws the Ellipse enclosed by the Rectangle. The arguments are like those of Path::draw() (see Path Reference; Drawing and Filling). The return value is the enclosed Ellipse.
