Subject RE: finding the transformed location of a svg group

Right, but did you try printing out the values for dest_x and dest_y in
your method to see if they're what you expect them to be?

Subject: Re: finding the transformed location of a svg group

Hi,
dest_x and dest_y are the coordinates of the element I'm trying to
place an ellipse over. I have a svg file representing a game board
where the fields are defined by grouped elements. What I'm trying to
achieve is to move a peeble (an ellipse) over the board.
