Class AdvancedShapeWriter

  • public class AdvancedShapeWriter
extends org.locationtech.jts.awt.ShapeWriter
    Enhances the jts ShapeWriter with handling the render process for Shapeable instances. In general, it shares a PointTransformation object to translate the Shapeable's Geometry into translated and scaled awt Shape's.
