The short answer is yes, but the question implies this represents significant effort which it should not. In theory you could pass the same element to 'getRoot' every time, this would make finding the new element(s) a little tricky so instead you might have two one you use to get the new elements and then a second that you 'transfer' those new elements to for later use. > Do you think it would be helpful to include a getCurrentElement() > API on SVGGraphics2D? The problem is that a single draw operation can generate several elements. Some in the draw tree some in the 'defs' tree. So adding the ability to call 'getCurrentElement' would significantly impact the quality of the generated SVG content in the more normal case of just drawing a bunch of stuff you want to save as SVG (every draw operation would have to result in a 'stand-alone' subtree, which would also probably mean needlessly introducing extra groups etc).
