I am trying to add an rect to the SVGDocument and then display it in the JFrame. The JSVGCanvas can only display things which are on the main.svg, I cannot get it to display the new rect element which i have just added. I hope someone would help me out. Thank you so much. The source code appended in the end of the message. 2. I cannot find the org.w3c.dom.svg.SVGDocument java source and documentation in batik 1.7. Is it only available in batik 1.5? Does anyone know where I can find it? Thank you very much.
