the arc is to begin.
• The seventh is the end angle where the arc is to end. If the current position does
not coincide with the position defined by X1, Y1, Radius and Start Angle, then
a straight line segment will be added from the current position to this point. A
smooth curve of the specified radius will be drawn from that specified point
counter-clockwise to the point specified by X1, Y1, Radius and End Angle. The
current position will be set to that ending point.
If the starting and ending points specify the same angle, a full circle will be drawn.
The position following this command will be the specified position.

This method accepts seven parameters:
• The first is a pointer to the path.
• The second is an Xposition of the arc center point.
• The third is the Yposition of the arc center point.
• The fourth is the horizontal radius (HRad) of the arc.
• The fifth is the vertical radius (VRad) of the arc. The HRad and VRad support
drawing elliptical arc segments.
• The sixth is the start angle (where zero is directly to the right of center) where
the arc is to begin.
• The seventh is the end angle where the arc is to end. If the current position does
not coincide with the position defined by X1, Y1, Radius and Start Angle, then
a straight line segment will be added from the current position to this point.
A smooth curve of the specified radius will be drawn from that specified point
clockwise to the point specified by X1, Y1, Radius and End Angle. The current
position will be set to that ending point. If the starting and ending points specify the
