Examples of org.apache.batik.svggen.SVGGraphics2D

3.org). At construction time, the SVGGraphics2D must be given a org.w3.dom.Document instance that is used as a factory to create the various nodes in the DOM tree it generates. The various graphic context attributes (e.g., AffineTransform, Paint) are managed by a GraphicContext object. @author Vincent Hardy @version $Id: SVGGraphics2D.java,v 1.33 2002/06/18 08:05:23 vhardy Exp $ @see org.apache.batik.ext.awt.g2d.GraphicContext @see org.apache.batik.svggen.DOMTreeManager @see org.apache.batik.svggen.DOMGroupManager @see org.apache.batik.svggen.ImageHandler @see org.apache.batik.svggen.ExtensionHandler @see org.w3c.dom.Document
