All Known Implementing Classes:
DefaultExtensionHandler

public interface ExtensionHandler

The ExtensionHandler interface allows the user to handler Java 2D API extensions that map to SVG concepts (such as custom Paints, Composites or BufferedImageOp filters.

Method Detail

handlePaint

public SVGPaintDescriptor handlePaint(java.awt.Paint paint,
                                      Document domFactory)
Parameters:
paint - Custom Paint to be converted to SVG
domFactory - allows the handler to build DOM objects as needed.
Returns:
an SVGPaintDescriptor

handleComposite

public SVGCompositeDescriptor handleComposite(java.awt.Composite composite,
                                              Document domFactory)
Parameters:
composite - Custom Composite to be converted to SVG.
domFactory - 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(java.awt.image.BufferedImageOp filter,
                                        java.awt.Rectangle filterRect,
                                        Document domFactory)
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.
domFactory - 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
