Method Detail

create

public static final PolyCubicBezierCurve2D create(Point2D[] points)
Creates a series a cubic bezier curves, by grouping 4 adjacent points. Two consecutive curves share one point, N curves will require 3*n+1 points.


create

public static final PolyCubicBezierCurve2D create(Point2D[] points,
                                                  Vector2D[] vectors)
Creates a series a cubic bezier curves, by grouping consecutive couples of points and vectors. A polycurve composed of N Bezier curves requires N+1 points and N+1 vectors.


clip

public PolyCubicBezierCurve2D clip(Box2D box)
Returns a new PolyCubicBezierCurve2D.

Specified by:
clip in interface ContinuousCurve2D
Specified by:
clip in interface Curve2D
Specified by:
clip in interface Shape2D
Overrides:
clip in class PolyCurve2D<CubicBezierCurve2D>
Parameters:
box - the clipping box
Returns:
the clipped shape

transform

public PolyCubicBezierCurve2D transform(AffineTransform2D trans)
Description copied from class: CurveArray2D
Transforms each curve, and build a new CurveArray2D with the set of transformed curves.

Specified by:
transform in interface ContinuousCurve2D
Specified by:
transform in interface Curve2D
Specified by:
transform in interface Shape2D
Overrides:
transform in class PolyCurve2D<CubicBezierCurve2D>
Parameters:
trans - an affine transform
Returns:
the transformed shape
