TEllipse Class Reference

Draw Ellipses.

The ellipse can be truncated and rotated. It is defined by its center (x1,y1) and two radius r1 and r2.

A minimum and maximum angle may be specified (phimin, phimax). The ellipse may be rotated with an angle theta. All these angles are in degrees. The attributes of the outline line are given via TAttLine. The attributes of the fill area are given via TAttFill. The picture below illustrates different types of ellipses.

When an ellipse sector only is drawn, the lines connecting the center of the ellipse to the edges are drawn by default. One can specify the drawing option "only" to not draw these lines or alternatively call the function SetNoEdges(). To remove completely the ellipse outline it is enough to specify 0 as line style.
