                      Point p3)

Description copied from interface: Arc

Sets the three points to define an arc. These are three ordered points that belong to the arc (none of them is the center of the ellipse/circle). Therefore they must not be aligned.

Specified by:

setPoints in interface Arc

Parameters:

p1 - The start point of an arc.

p2 - The middle point of an arc.

p3 - The end point of an arc.
