Actually I am aware of the transform attribute but as the requirement is for a drawing tool the user/artist/designer would keep iterating on an element ( may be 1000 times ) by repeatedly scaling an element till he is satisfied which means if I keep adding transform there would be 1000s of transforms. Now I read the SVG DOM APIs but am not sure if there is a direct api to change the scale or rotate values of a transform element,
I saw a DOM interface called SVGTransform and there is also an api called "setScale" in this link http://www.w3.org/TR/2003/REC-SVG11-20030114/coords.html#InterfaceSVGTransform but how am I going to get the SVGTransform object is what I could not find - Raks A On Tue, Jan 11, 2011 at 1:45 AM, [email protected] <[email protected]> wrote: > > > --- In [email protected] <svg-developers%40yahoogroups.com>, > Raks A <raks...@...> wrote: > > > > But what are the browsers which support all the SVG DOM Apis. > > I think at leats getBBox() is supported by all of them (as mentioned, > getScreenBBox() unfortunately isn't). > > > > We are > > creating a drawing tool where we want to allow the users to scale and > rotate > > a closed path using the mouse.
