public class SVGComposite extends Object implements SVGConverter
Utility class that converts a Composite object into a set of SVG properties and definitions.

Here is how Composites are mapped to SVG:

  • AlphaComposite.SRC_OVER with extra alpha is mapped to the opacity attribute
  • AlphaComposite's other rules are translated into predefined filter effects.
  • Custom Composite implementations are handled by the extension mechanism.
