Method Summary

SVGCompositeDescriptor	handleComposite(Composite composite, SVGGeneratorContext generatorContext)
SVGFilterDescriptor	handleFilter(BufferedImageOp filter, Rectangle filterRect, SVGGeneratorContext generatorContext)
SVGPaintDescriptor	handlePaint(Paint paint, SVGGeneratorContext generatorContext)

Method Detail

handlePaint

SVGPaintDescriptor handlePaint(Paint paint,
                               SVGGeneratorContext generatorContext)

Parameters:

paint - Custom Paint to be converted to SVG

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

Returns:

an SVGPaintDescriptor

handleComposite

SVGCompositeDescriptor handleComposite(Composite composite,
                                       SVGGeneratorContext generatorContext)

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

SVGFilterDescriptor handleFilter(BufferedImageOp filter,
                                 Rectangle filterRect,
                                 SVGGeneratorContext generatorContext)

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
