All Implemented Interfaces:
ErrorConstants

public class SVGGeneratorContext
extends Object
implements ErrorConstants

This class contains all non graphical contextual information that are needed by the SVGGraphics2D to generate SVG from Java 2D primitives. You can subclass it to change the defaults.
