displaying SVG from a string

[Tobin Fricke <to...@splorg.org>]

I see that the JSVGCanvas class has a "setURI" method to fetch an SVG from
some URI.  However, I have an SVG document in a String... I just want to
give this SVG string to the JSVGCanvas and have it display it.  How should
I accomplish this?

Secondly, what's the proper way to build something that has a dependency
on Batik?  i.e., what classpath do I use?

thanks,
Tobin

    Turn the String into a Reader (java.io.StringReader), parse it into
a DOM tree using the org.apache.batik.dom.svg.SAXSVGDocumentFactory
class.  Give the resulting document to the canvas
JSVGCanvas.setSVGDocument.

    Depends on what you want or need out of the Batik toolkit.
Take a look at http://xml.apache.org/batik/install.html#jarFiles for
a diagram of jar file dependencies.  You could also just build your
own jar file the ant build file has an 'all-jar' target that builds
one jar file that includes everything.

    You might also look at the manifest files for the batik
applications to see how they work.

Here is the example
StringReader reader = new StringReader(someString);
try {
	String parser = XMLResourceDescriptor.getXMLParserClassName();
        SAXSVGDocumentFactory f = new SAXSVGDocumentFactory(parser);
        doc = f.createSVGDocument(baseDocumentURI,reader);
} catch (Exception ex) { }
jsvgCanvas.setDocument(doc);
