Constructor Detail

FigSpline

public FigSpline(int x0,
                 int y0,
                 boolean is_closed,
                 FigAttribs attribs,
                 FigTrafo2D trafo)

Method Detail

createRenderer

public void createRenderer()

Overrides:

createRenderer in class FigPolyline

round

final int round(double x)

getSplinePoints

public java.awt.Point[] getSplinePoints()

toString

public java.lang.String toString()

Description copied from class: FigPolyline

toString() for debug purposes.

Specified by:

toString in interface FigObject

Overrides:

toString in class FigPolyline

rebuild

public void rebuild()

Description copied from class: FigPolyline

rebuild all internal data-structures for this polyline. This method re-calculates all internal data required for fast rendering from the world-coordinate control points, attributes, and FigTrafo2D coordinate transformation data. Therefore, this method is computationally expensive and should only be called when necessary.

Specified by:

rebuild in interface FigObject

Overrides:

rebuild in class FigPolyline

copy

public FigObject copy()

create a copy of this FigSpline.

Specified by:

copy in interface FigObject

Overrides:

copy in class FigPolyline
