SVG position in parent document

[Tony Cox]

I'm trying to get drag 'n' drop working in an SVG embedded in an XML
document (a Mozilla XUL document). To get the mouse pointer offset
working properly I need to know the offset of the origin of the SVG
document in the parent page. Could somebody advise me how to do that
please or point me to an example?

thanks

Tony

aha, yes, the magic incantation is

getScreenCTM()

many thanks!

Tony

p.x = evt.clientX;
p.y = evt.clientY;
screenCTMInv = getScreenCTM().inverse();
p = p.matrixTransform(screenCTMInv);
