I want to use batik to generate svg and display it, and I have a xml
configuration file(meta.xml). I read configuration from the meta.xml
and use batik to generate the corresponding svg,but it can't display
in JSVGCanvas. But if I use SVGGraphics2D,it works fine,see comment
code.I don't where the problem is,and I hope some help,thanks.
