Re: add image to bounding box

[Andreas Neumann]

Hi Peppe,

http://www.carto.net/papers/svg/manipulating_svg_with_dom_ecmascript/index.shtml
contains a tutorial on how to manipulate the DOM with Javascript. 
Althought this targets ECMAScript, the same methods also apply to Java.

In your example, the bbox does not really exist. It is a SVGRect object 
(with x,y,width,height) properties. You need to add your new image 
somewhere in the DOM, using methods like .appendChild() or 
.insertBefore(). Be aware that images use the xlink namespace when you 
specify the "href" attribute. You have to explicitly set the namespace 
for this attribute, e.g.

image.setAttributeNS("http://www.w3.org/1999/xlink","href","myImage.png";);

Hope this helps,
Andreas

Hi, i have an Element "shape" and then i get its bbox in this way : 
SVGRect shapeBound = ((SVGLocatable)shape).getBBox();

Now i want to add images (they are arrows in jpeg format) in some points of
bbox...how can i do this? is there a method to add image to bbox?
