Thanks, getGlobalTransform made it.
Hi Guillaume,
I would test this code on an element that has a 'transform' attribute. I suspect that this code will apply the transform from the element twice. You probably need to use getGlobalTransform on the parent GraphicsNode of theNode or concatenate the inverse of theNode's transform.
Here is the code I use, in the case somebody is interested:
AffineTransform theTransform = new AffineTransform(SVGContentManager.TRANSFORM_96DPI);
theTransform.concatenate(theNode.getGlobalTransform());
Rectangle2D theBounds = theNode.getTransformedBounds(theTransform);
I get the bounds in mm, not pixels.

Hi!
I have a SVG document with its root <svg> tag, a few geometric objects, and a child <svg>, which in turn contains a few geometric objects. Once the GVT tree is built, I get the GraphicNode corresponding to one of the rectangles in the embedded svg node. If I call getTransformedBounds on it, it seems that I am getting its bounds within the embedded svg node, and not relative to the root svg node.
getTransformedBounds returns the bounds in the coordinate system defined by the affine you pass in, relative to the Node. So what Affine are you passing into the function?
My question: should getTransformedBounds return the bounds relative to the root svg node, and should I try to find the error on my side, or is it normal for getTransformedBounds to return the bounds relative to the parent svg node, in which case, is there a method to obtain the bounds relative to the root svg element?
It depends on what transform you pass in. For the Identity Affine it will return it's bounds in it's parent's coordinate system. You might want to look at getGlobalTransform() you probably need to use the inverse of that affine and remove the transform, if any, from the element it's self (getTransform()).
