paint - Custom Paint to be converted to SVG
generatorContext - allows the handler to build DOM objects as needed.
Returns:
an SVGPaintDescriptor

handleComposite

public SVGCompositeDescriptor handleComposite(Composite composite,
                                              SVGGeneratorContext generatorContext)
Specified by:

Parameters:
composite - Custom Composite to be converted to SVG.
generatorContext - allows the handler to build DOM objects as needed.
Returns:
an SVGCompositeDescriptor which contains a valid SVG filter, or null if the composite cannot be handled

handleFilter

public SVGFilterDescriptor handleFilter(BufferedImageOp filter,
                                        Rectangle filterRect,
                                        SVGGeneratorContext generatorContext)
Specified by:

Parameters:
filter - Custom filter to be converted to SVG.
filterRect - Rectangle, in device space, that defines the area to which filtering applies. May be null, meaning that the area is undefined.
