Hey everyone,

I am using Raphael js to draw circled numbers. The problem is that each number has a different width/height so using one set of coordinates to center the text isn't working. The text displays differently between IE, FF, and safari. Is there a dynamic way to find the height/width of the number and center it accordingly?

Here is my test page:

and my code:

function drawcircle(div, text) { 
    var paper = Raphael(div, 26, 26); //<<
    var circle = paper.circle(13, 13, 10.5);
    circle.attr("stroke", "#f1f1f1");
    circle.attr("stroke-width", 2);
    var text = paper.text(12, 13, text); //<<
    text.attr({'font-size': 15, 'font-family': 'FranklinGothicFSCondensed-1, FranklinGothicFSCondensed-2'});
    text.attr("fill", "#f1f1f1");
}

window.onload = function () {
    drawcircle("c1", "1");
    drawcircle("c2", "2");
    drawcircle("c3", "3");
};

Thanks very much!
