net.sf.jasperreports.engine.export
Class JRGraphics2DExporter

java.lang.Object
  net.sf.jasperreports.engine.JRAbstractExporter
      net.sf.jasperreports.engine.export.JRGraphics2DExporter

All Implemented Interfaces:

JRExporter

public class JRGraphics2DExporter
extends JRAbstractExporter

Exports a JasperReports document to a Graphics2D object. Since all font measurement and layout calculation during report filling is done using AWT, this is considered the perfect exporter, unlike the others, which are only approximations of the initial document.

As its name indicates, this exporter is special because it does not produce files or does not send character or binary data to an output stream.
