yes, you can use var ctm = myElement.getTransformToElement(document.documentElement);
which would give you the transform matrix from your current node to the root element. Of course you can use any other node in the hierarchy instead of document.documentElement as argument. You can also use var ctm = myElement.getCTM(); which gives you the ctm from your element to the element's parent node. Note that .getTransformToElement() doesn't work in ASV3, but .getCTM() works. You need a workaround here, see code below. ------------------ //this code is copied from Kevin Lindsey //http://www.kevlindev.com/tutorials/basics/transformations/toUserSpace/index.htm function getTransformToRootElement(node) { try { //this part is for fully conformant players var CTM = node.getTransformToElement(document.documentElement); } catch (ex) { //this part is for ASV3 or other non-conformant players // Initialize our CTM the node's Current Transformation Matrix var CTM = node.getCTM(); // Work our way through the ancestor nodes stopping at the SVG Document while ( ( node = node.parentNode ) != document ) { // Multiply the new CTM to the one with what we have accumulated so far CTM = node.getCTM().multiply(CTM); } } return CTM; } --------------------- See also http://www.w3.org/TR/SVG11/coords.html#TransformMatrixDefined on how to interpret the matrix.
