Constructor Detail

CircleInversion2D

public CircleInversion2D()

Construct a new circle inversion based on the unit circle centered on the origin.

CircleInversion2D

public CircleInversion2D(Circle2D circle)

Method Detail

getCenter

public Point2D getCenter()

getRadius

public double getRadius()

setCircle

public void setCircle(double xc,
                      double yc,
                      double r)

setCircle

public void setCircle(Circle2D circle)

transformShape

public Shape2D transformShape(Shape2D shape)

Transforms a general shape, and return the transformed shape.

Transformed shape can be computed for different cases:

• Point2D is transformed into another Point2D
• LinearShape2D is transformed into a CircleArc2D or a Circle2D
• Circle2D is transformed into another Circle2D
• Polyline2D is transformed into a continuous set of circle arcs

transform

@Deprecated
public Shape2D transform(Shape2D shape)

Deprecated. use transformShape() instead (0.7.0)

transformPoint

public Point2D transformPoint(Point2D pt)

transformRing

public BoundaryPolyCurve2D<CircleArc2D> transformRing(LinearRing2D ring)

transform

public Point2D transform(Point2D pt)
