Dear All,
1. 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.
Kind regards,
Qian
