Method Details
-
handlePaint
- Parameters:
paint
- Custom Paint to be converted to SVGgeneratorContext
- allows the handler to build DOM objects as needed.- Returns:
- an SVGPaintDescriptor
-
handleComposite
- 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:
