           Summary: Problem with converting WMF files to SVG Documents
           Product: Batik
           Version: 2.0
          Platform: PC
        OS/Version: Windows XP
            Status: NEW
          Severity: normal
          Priority: P2
         Component: SVGGraphics2D
        AssignedTo: [email protected]
        ReportedBy: [EMAIL PROTECTED]


It seems not possible to convert directly WMF files to SVG Documents. An
Exception is explicitely raised in WMFTranscoder if  trying to do so. Further,
if trying to removed this Exception raising, the resulting SVG Document has no
content, appart for the svg root Element.

The cause of this problem seems in fact to be the getRoot() method in the
SVGGraphics2D class : the code is simply :
    public Element getRoot(){
        return getRoot(null);
    }
which calls in the same class :
    public Element getRoot(Element svgRoot) {
        svgRoot = domTreeManager.getRoot(svgRoot);
        ...
        return svgRoot;
    }

The DOMTreemanager creates a new svg Element in the tree, even if it already
exists. I think the code in SVGGraphics2D  should be something like that :
    public Element getRoot(){
        Document doc = getDOMFactory();
        Element elt = doc.getDocumentElement();
        if (elt.getTagName().equals(SVGConstants.SVG_SVG_TAG)) return 
getRoot(elt);
        else {
            NodeList list = elt.getElementsByTagName(SVGConstants.SVG_SVG_TAG);
            if ((list == null) || (list.getLength() == 0))  return 
getRoot(null);
            else return getRoot((Element)(list.item(0)));
        }
        return getRoot(null);
    }
