Hi Julien,
You should be able to load the document, and subsequently calculate
a bbox without actually rendering the document.
Try some sequence like...
InputStream templateStream =
MyClass.class.getResourceAsStream("mysvg.svg"); //
String parser = XMLResourceDescriptor.getXMLParserClassName();
SAXSVGDocumentFactory f = new SAXSVGDocumentFactory(parser);
SVGDocument doc = null;
try {
doc = f.createSVGDocument(null, templateStream);
} catch (IOException ex) {
} finally {
}
NodeList rects = doc.getElementsByTagName("rect");
SVGRect bbox = null;
for(int i = 0;i < rects.getLength();i++) {
bbox = ((SVGLocatable)rects[i]).getBbox();
//transforms, etc if needed
}
