public class AstFigureProps
extends FigureProps

Subclass of FigureProps that can convert a Figure between coordinates systems using a Mapping when restoring from an XML serialization.

This class is intended to be used as a replacement for FigureProps is intended for use when restoring figures that are stored in some coordinate system that needs modifying to align with the system now in use.

public AstFigureProps(FigureProps props)

Create an instance which is a copy of an existing FigureProps.

Method Detail

decode

public void decode(Element rootElement,
                   Mapping oldMapping,
                   Mapping newMapping)

Decode using the given mappings to transforming stored coordinates to world coordinates, and world coordinates to current graphics coordinates.

Usually the oldMapping will be the Plot in force when the figures were encoded and newMapping will be the current Plot.

transform

public void transform(Rectangle2D.Double r,
                      Mapping mapping)

Transform a Rectangle using a given mapping.

transform

public void transform(double[] x,
                      double[] y,
                      Mapping mapping)

Transform arrays of coordinates using a mapping.
