Constructor Detail

DefaultArc

public DefaultArc(Point p1,
                  Point p2,
                  Point p3)

Creates a new DefaultArc instance from the given parameters.

Parameters:

p1 - first control point

p2 - second control point

p3 - third control point

Method Detail

getPoint1

public Point getPoint1()

Description copied from interface: Arc

Returns the first of the three control points.

Specified by:

getPoint1 in interface Arc

Returns:

the first control point

getPoint2

public Point getPoint2()

Description copied from interface: Arc

Returns the second of the three control points.

Specified by:

getPoint2 in interface Arc
