I am generating SVG object using jQuery SVG plug-in. The problem is how can I convert it into image in my script.

My script is following:

<html>
<head>        
<script type="text/javascript" src="jquery-latest.min.js"></script>                
<script type="text/javascript" src="jquery.svg.js"></script>
<script type="text/javascript">
$(function(){
  $("#draw").click(function(){
     $('#svg_container').svg();
     svg = $('#svg_container').svg('get');
     svg.clear(true);
     svg.circle(200, 220, 150, {fill: "red", stroke: "blue", strokeWidth: 5});
     alert(svg.toSVG()); //this prints svg source of the generated image, i.e. circle
  });
});
</script>
</head>
<body>
<div id="svg_container" style="position: absolute; left: 100px; top: 100px; width: 400px; height: 400px; border: thin solid #4297D7;"></div>
<button id="draw">Draw</button>
</body>
</html>

I have tried out this and this but without success.

Could you please show me how to convert this svg into any type of image?

Thanks in advance.

UPDATE

The problem is solved and I have posted the solution as an answer, check it here.

Reset to default 6

This seams to be very hard to do.

I found this project that attempts to do this:

http://www.svgopen/2010/papers/62-From_SVG_to_Canvas_and_Back/index.html

I also found one project that tried to build a SVG renderer for Canvas but it was far from plete.

They did use a solution to go by the server and have the SVG rendered to PNG there, that might be the only really working solution right now.

I have finally solved the problem of converting SVG to image file. Here is the solution, if anybody is interested in:

<html>
<head>        
<script type="text/javascript" src="jquery-latest.min.js"></script>                
<script type="text/javascript" src="jquery.svg.js"></script>
<script type="text/javascript" src="http://canvg.googlecode./svn/trunk/rgbcolor.js"></script>
<script type="text/javascript" src="http://canvg.googlecode./svn/trunk/canvg.js"></script>

<script type="text/javascript">
$(function(){
    function q(k){
       var qs = window.location.search.substring(1);
       var t = qs.split("&");
       for (i=0;i<t.length;i++) {
        kv = t[i].split("=");
            if (kv[0] == k) return unescape(kv[1]).replace('+',' ');
       }
       return null;
    }

    var context;
    function bodyonload() {
       if (typeof(FlashCanvas) != 'undefined') context = document.getElementById('canvas').getContext;
       var qUrl = q('url'); if (qUrl != null && qUrl != '') { r(); canvg('canvas', qUrl); }
       var qSvg = q('svg'); if (qSvg != null && qSvg != '') { r(); canvg('canvas', qSvg); }
    }

    function render() {
       var c = document.getElementById('canvas');
       c.width = 400;
       c.height = 500;
       if (context) c.getContext = context;
       canvg(c, document.getElementById('svg').value);
       var svg_content = c.toDataURL();
       $.ajax({
                 type:"POST",
                 url:"svg.php",
                 data: ({
                      svg_content: svg_content
                 }),
                 timeout: 30000, //30 sec.                            
       });
    }   

    function r() {
        var c = document.getElementById('canvas');
        c.width = '1000'; //change it to the width of your image
        c.height = '600'; //change it to the height of your image
        if (context) c.getContext = context;
    }

    $("#save").click(function(){
        render();
    });

    $("#draw").click(function(){
        $('#svg_container').svg();
        svg = $('#svg_container').svg('get');
        svg.clear(true);
        svg.circle(200, 220, 150, {fill: "red", stroke: "blue", strokeWidth: 5});
        $("#svg").val(svg.toSVG());
    });
});
</script>
</head>
<body>
<textarea id="svg" rows="5" cols="50" style="visibility: hidden;"></textarea><br />
<canvas id="canvas" width="1000px" height="600px"></canvas>
<div id="svg_container" style="position: absolute; left: 100px; top: 100px; width: 400px; height: 400px; border: thin solid #4297D7;"></div>
<button id="draw" style="position: absolute; top:400px; left: 500px;">Draw</button>
<button id="save" style="position: absolute; top:400px; left: 550px;">Save</button>
</body>
</html>

The content of svg.php is following:

<?php
if (isset($_POST['svg_content'])){
     $imageData=$_POST['svg_content'];
     $filteredData=substr($imageData, strpos($imageData, ",")+1);
     $unencodedData=base64_decode($filteredData);
     $fp = fopen('test.png', 'wb' );
     fwrite( $fp, $unencodedData);
     fclose( $fp );
}
?>

You can download jQuery library (jquery-latest.min.js) from jQuery official web site and jQuery SVG library from here .

Hope this will help to many of you who are looking toward converting SVG to image right from your program.

Best,

Bakhtiyor
