how to get position and size of a SVG group
I got a group ( <g> ) by ID from a document and want to know the position
and size of the group.
With 'position' I mean the upper left corner of an imaginary rectangle
arround all elements of the group. 'Size' should be the edge length of the
rectangle...
How can I do this ?
Thanks
Maik

Thanks Urs,
yes, thats the way. It works fine.
If you have at minimum a instanceof SVGGraphicsElement, you can get position
and size via getBBox() / getX() etc.

I've thought about this myself, recently, and though I have not tested this,
I figured the easiest way would be to get the bounding box of the
g-element by calling "getBBox()" and afterwards checking the respective
parameters of that bounding box via getX(), getY(), getWidth() and getHeight().
As I said, it's untested, but I hope it works - if it doesn't, please post your
solution to the ML.
Bye
