RE: SVGOMGElement and coordinates?

[Pepping, Florian]

Hi Nazar,   well on first look, everythings ok. I used your SVG in my program and got all Bounding-Boxes as I'm used to. Two things: First of all, you only operate on elements containing an "activity-label"-attribute An second try to call your visit-function with the root-Node of your SVGDocument. visit((Node) doc.getRootElement(), 0);   Perhaps that helps   Florian From: Nazar Stasiv (Lohika, Inc) [mailto:[EMAIL PROTECTED] Sent: Tuesday, August 15, 2006 2:10 PM To: batik-users@xmlgraphics.apache.org Subject: Re: SVGOMGElement and coordinates?

Attached diagram.zip archive which contains svg resource   Is it possible that's something wrong with your recursion through the DOM-Tree, because it's only the root-node that has a Bounding Box?! Do you operate the other nodes? well the recursion is pretty basic. Here is how I do it     public static SVGDocument installScript(SVGDocument doc,             Collection<String> labels) {         // add to dom tree element with id=background to use it in draggable         // functions         Element parent = doc.createElement("g");         parent.setAttribute("id", "background");         Element svg = doc.getRootElement();         NodeList children = svg.getChildNodes();         for (int i = 0; i < children.getLength(); i++) {             Node n = children.item(i);             svg.removeChild(n);             parent.appendChild(n);         }         svg.appendChild(parent);         // Append script element with reference to library file         Element sc = doc.createElementNS(svgns, "script");         sc.setAttributeNS(svgns, "language", "text/ecmascript");         sc.setAttributeNS(xlinkns, "href", "svg-common.js");         doc.getDocumentElement().appendChild(sc);         // add onload attribute to svg element         NodeList list = doc.getElementsByTagNameNS(null, "svg");         Element svgNode = (Element) list.item(0);         svgNode.setAttributeNS(svgns, "onload", "init(evt);");         // Append array of activities to be highlighted         Element data = "" "script");         data.setAttributeNS(svgns, "language", "text/ecmascript");         StringBuilder sb = new StringBuilder();         sb.append("var labels = [ ");         for (String label : labels) {             sb.append("'");             sb.append(label);             sb.append("',");         }         sb.replace(sb.length() - 1, sb.length(), "];");         CDATASection cdata = doc.createCDATASection(sb.toString());         data.appendChild(cdata);         doc.getDocumentElement().appendChild(data);         // HERE I START WALKING THE DOM TREE         visit(doc, 0);         return doc;     }     public static void visit(Node node, int level) {         // Process node         if (node instanceof Element) {             Element e = (Element) node;             if (e.hasAttributeNS("http://www.example.com/bpms",                     "activity-label")) {                 // I love painting in red                 String style = e.getAttribute("style");                 Pattern pattern = Pattern.compile("fill:([a-zA-Z])*;");                 Matcher m = pattern.matcher(style);                 e.setAttribute("style", m.replaceAll("fill:red;"));                 if (e instanceof SVGLocatable) {                     SVGLocatable l = (SVGLocatable) node;                     if (svgTagSet.contains(node.getNodeName())) {                         SVGRect r = l.getBBox();                         try {                             float x = r.getX();                             float y = r.getY();                              // setting onclick attribute is only for testing here                             e.setAttribute("onclick",                                     "drawMarker(evt,'sampletext','" + x + "','" + y                                             + "');");                          } catch(Exception e ){                             e.printStackTrace();                         }                     }                 }             }         }         // If there are any children, visit each one         NodeList list = node.getChildNodes();         for (int i = 0; i < list.getLength(); i++) {             // Get child node             Node childNode = list.item(i);             // Visit child node             visit(childNode, level + 1);         }     }   Greets Florian
