"getBBox" applies to all elements that implement the 'SVGLocatable' interface which certainly includes the 'g' and 'svg' element. > --- In svg-developers@yahoogroups.com, "rwkemper" <[EMAIL PROTECTED]> > wrote: > > why does the code below not work with the rectangle in the group ?? > > In case I commented it out (as shown here , I get an x and y value > > by getBBox. In case it's active the result is 0 , 0 !! It does work you just need to understand the meaning of the values returned. 'getBBox' returns the bounding box in the _userspace_ of the element you call it on. In this case the 'g' with 'id="x"'. The bounding box of the text and the rect is the rect's bounds (it would appear that all the text lies within the rect). The rects bounds in the userspace of the 'g' is 0,0 -> 80,50. So the x & y _should_ be 0,0. > > <g id="x" transform="translate(10,10)" > > > <text id="text1" x="20" y="50" fill="red" font-size="25">SVG</text> > > <!-- <rect x="0" y="0" height="50" width="80" fill="red" > > stroke="none" /> --> > > </g> You may be interested in using the bbox in a seperate coordiate system like the parent of the g's coordinate system. To do this you may want to investigate methods like 'getTransformToElement' or 'getScreenCTM'. To get transforms between coordinate systems which can be used to map the corners of your BBox to other coordinate systems. ------------------------ Yahoo!
