Method Detail

handlePaint

public SVGPaintDescriptor handlePaint(Paint paint,
                                      SVGGeneratorContext generatorContext)

Specified by:

handlePaint in interface ExtensionHandler

Parameters:

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:

handleComposite in interface ExtensionHandler

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:

handleFilter in interface ExtensionHandler

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.

generatorContext - allows the handler to build DOM objects as needed.

Returns:

an SVGFilterDescriptor which contains a valid SVG filter, or null if the composite cannot be handled
