isAvailable

public static boolean isAvailable()

getExporter

public static Exporter getExporter(String type,
                                   String orientation,
                                   String format,
                                   OutputStream stream)

Returns an Exporter object if the exporting library is available, otherwise null. The following output types are supported: ps, pdf, swf, emf, svg, png, gif, jpg, bmp

Parameters:

type - describes the output format

orientation - one of {Portrait,Landscape}

stream - the stream to redirect the output to

Returns:

an instance of an Exporter

setType

protected abstract void setType(String type)

setOutputStream

protected abstract void setOutputStream(OutputStream stream)

export

public abstract void export()

This method should be called when the generation of the diagram has finished and PaintDevice.computeBounds() has been called. It redirects the output to the stream set via setOutputStream(OutputStream).
