When does an SVGLocatable have a bounding box?

["Bishop, Michael W. CONTR J9C880" <Mi...@je.jfcom.mil>]

The following results in "null" being printed:

 

Element someElement = SVGShape.toShape(someShape);

SVGRect boundingBox = ((SVGLocatable) someElement).getBBox();

if (boundingBox == null) {

    System.out.println("Null!");

}

 

Must it be rendered to the JSVGCanvas first?  How can I derive the
center point of any given element as soon as the element has been
created?

   It must be part of the rendering tree to have a bbox, it does not 
have to have been rendered yet.  So if you add it to the tree first
and then calculate the various transforms you should be fine.
