Constructor Detail

Java2DConverter

public Java2DConverter(Java2DConverter.PointConverter pointConverter)

Create a Java2DConverter based on pointConverter and using a default resolution of 0.5 pixel for decimation.

Parameters:

pointConverter - the PointConverter to convert coordinates from Model to View

Java2DConverter

public Java2DConverter(Java2DConverter.PointConverter pointConverter,
                       double resolution)

Create a coordinate converter using a custom resolution for decimation.

Parameters:

pointConverter - the PointConverter to convert coordinates from Model to View

resolution - resolution in pixels for decimation

Method Detail

toViewCoordinates

public org.locationtech.jts.geom.Coordinate[] toViewCoordinates(org.locationtech.jts.geom.Coordinate[] modelCoordinates)
                                                         throws NoninvertibleTransformException

Throws:

NoninvertibleTransformException

toShape

public Shape toShape(org.locationtech.jts.geom.Geometry geometry)
              throws NoninvertibleTransformException

If you pass in a general GeometryCollection, note that a Shape cannot preserve information about which elements are 1D and which are 2D. For example, if you pass in a GeometryCollection containing a ring and a disk, you cannot render them as such: if you use Graphics.fill, you'll get two disks, and if you use Graphics.draw, you'll get two rings. Solution: create Shapes for each element.

Throws:

NoninvertibleTransformException
