procedure Arc(X,Y: Double; Radius: Double; StartAngle, EndAngle:
      Double; CounterClockwise: Boolean=False)

Available In: Visual Client Applications

Use this method to add an arc to the current subpath of the canvas. The first three parameters specify the center and radius of a circle. The next two parameters are angles (in radians) that specify the start and end points of an arc along the circle. The last parameter specifies whether the arc is traversed counterclockwise or clockwise along the circle's circumference.
