Constructor Summary

ShapeWriter()
Creates a new ShapeWriter with the default (identity) point transformation.

ShapeWriter(PointTransformation pointTransformer)
Creates a new ShapeWriter with a specified point transformation and the default point shape factory.

ShapeWriter(PointTransformation pointTransformer, PointShapeFactory pointFactory)
Creates a new ShapeWriter with a specified point transformation and point shape factory.

Method Summary

Constructor Detail

ShapeWriter

public ShapeWriter(PointTransformation pointTransformer,
                   PointShapeFactory pointFactory)

Creates a new ShapeWriter with a specified point transformation and point shape factory.

Parameters:

pointTransformer - a transformation from model to view space to use

pointFactory - the PointShapeFactory to use

ShapeWriter

public ShapeWriter(PointTransformation pointTransformer)

Creates a new ShapeWriter with a specified point transformation and the default point shape factory.

Parameters:

pointTransformer - a transformation from model to view space to use

ShapeWriter

public ShapeWriter()

Creates a new ShapeWriter with the default (identity) point transformation.

Method Detail

toShape

public java.awt.Shape toShape(Geometry geometry)

Creates a Shape representing a Geometry, according to the specified PointTransformation and PointShapeFactory (if relevant).

Note that Shapes do not preserve information about which elements in heterogeneous collections are 1D and which are 2D. For example, a GeometryCollection containing a ring and a disk will render as two disks if Graphics.fill is used, or as two rings if Graphics.draw is used. To avoid this issue use separate shapes for the components.

Parameters:

geometry - the geometry to convert

Returns:

a Shape representing the geometry
