Thank you for the quick response. The script works correctly now, and I kind of figured that the scrollbar on the browser was messing some things up, but the strange thing is that safari computes the data correctly. I am just now learning about svg and how to use script to control svg. It appears that the svg webkit by Brad Neuberg has a zoom and pan prototype that he is working on that will work with his cross browser flash render engine. Have you had any success in getting this to work? If so do you have any tips or sites that may help?

Have not been able to find any samples that show how Brad is getting it to work.

Thanks again,

James.

Hope it helps.

Regards,
Andrea

Any ideas why this might be?

var delta;
if (evt.wheelDelta) {
   delta = evt.wheelDelta / 3600; // Chrome/Safari
}
else {
   delta = -1 * evt.detail / 90; // Mozilla
}
var z = 1 + delta; // Zoom factor: 0.9/1.1

This version reversed the zooming direction (up -> zoom in, down -> zoom out) so that it’s consistent with zooming behavior in browsers. The zoom factor is now consistent across browsers as well.

setupHandlers(root)

window.addEventListener(’DOMMouseScroll’, handleMouseWheel, false);

if (navigator.userAgent.toLowerCase().indexOf(’webkit’) >= 0) {
window.addEventListener(’mousewheel’, handleMouseWheel, false); // Chrome/Safari
}
else {
window.addEventListener(’DOMMouseScroll’, handleMouseWheel, false);
}

handleMouseWheel(evt)

var z = 1.00 + delta / 90; // Zoom factor: 0.9/1.1

var z;
if (evt.detail) {
z = 1.00 + delta / 90; // Zoom factor: 0.9/1.1
}
else {
z = 1.00 + evt.wheelDelta / 1200; // Zoom factor: 0.9/1.1
}
