I do need to develop these tooltips rather than use the existing supported ones as they may become fairly intricate in the future. We only need to support Adobe Viewer, so I've tried to use some JS similar to that in the mapApp.js as suggested. I call it like this... function getMyCoords(evt){ // Pass in the event from the screen var thePoint = calcCoord(evt); // get the zoomed/panned values from the point x = thePoint.getX(); y = thePoint.getY(); } ... is this the correct way to get the real values? Its doesn't seem to work when zoomed or not. The values that are returned from this seem to very small compared to the locations I'd expect in the document... EG values less than 10 where I'd expect values in the hundreds. If this syntax is correct I'll look elsewhere for where my problem lies. Thanks again for any (more) help, Kind regards, Dylan. -----Original Message----- From: Andreas Neumann [mailto:neumann@karto.baug.ethz.ch] Sent: 13 June 2006 15:57 To: batik-users@xmlgraphics.apache.org Subject: Re: Accessing event coordinates when zoomed Hi Dylan, .getScreenCTM() is your friend here. Here is some code: function calcCoord(evt) { var svgPoint = document.documentElement.createSVGPoint(); svgPoint.x = evt.clientX; svgPoint.y = evt.clientY; var matrix = evt.target.getScreenCTM(); //alternatively use a different node reference here instead of evt.target, f.e. if you want to calculate to a different node in the hierarchy svgPoint = svgPoint.matrixTransform(matrix.inverse()); return svgPoint; } If you need standard tooltips, Batik already provides tooltips. Unfortunately, the Adobe SVG viewer version 3 neither supports tooltips nor .getScreenCTM. For this viewer there is a workaround: http://www.carto.net/papers/svg/gui/mapApp/ And here is a tooltip example that works in all browsers: http://www.carto.net/papers/svg/gui/tooltips/index.svg All the best, Andreas Dylan Browne wrote: >Hi, > >(Not strictly a Batik Posting, although I am using Batik DOM to create my >SVG, so I hope that almost counts...!) > >I am using JavaScript "evt.clientX" and "evt.clientY" (I have also tried >"screenX") to retrieve the co-ordinates of a mouseover event, and some extra >code then displays a label using these coordinates.
