I am attempting to convert a SVG to Canvas using Canvg. Here is the jsfiddle. I get an error saying, "ERROR: Element 'parsererror' not yet implemented". I can understand that the canvg library is not able to parse the SVG element. But, Is there a solution to this problem ? I need to create a canvas element from svg element.
<head>

<body>
<div id="chart"></div>
<button onclick="myFunction()">Save</button>
<header><h1>Canvas:</h1></header>
<canvas id="svg-canvas"></canvas>
<script>
var chart = {};
chart = c3.generate({
bindto: '#chart',
data: {
xs: {
'data1': 'x1',
'data2': 'x2',
},
columns: [
['x1', '2013-01-01 03:11:37', '2013-01-02 03:11:37', '2013-02-03 03:11:37', '2013-03-04 03:11:37', '2013-03-05 03:11:37', '2013-04-06 03:11:37'],
['x2', '2013-01-04 03:11:37', '2013-01-22 03:11:37', '2013-04-13 03:11:37', '2013-05-04 03:11:37', '2013-05-02 03:11:37', '2013-06-06 03:11:37'],
['data1', 30, 200, 100, 400, 150, 250],
['data2', 20, 180, 240, 100, 190,230]
],
xFormat: '%Y-%m-%d %H:%M:%S',
names: {
data1: 'Success',
data2: 'Failure',
}
},
axis: {
x: {
type: 'timeseries',
tick: {
format: '%Y-%m-%d %H:%M:%S',
count : 5
}
}
},
zoom: {
enabled : true,
rescale: true,
extent: [1, 100]
}
});
chart.show(['data2']);
function myFunction() {
var $container = $('#chart'),
// Canvg requires trimmed content
content = $container.html().trim(),
canvas = document.getElementById('svg-canvas');
// Draw svg on canvas
canvg(canvas, content);
}
</script>
</body>
</html>
P.S : The svg element is created by C3.js (D3.js based reusable library).

As suggested in the comments and on the working jsfiddle, explicitly set tick and path characteristics before generating the canvas:
<div id="chart"></div>
<button id="save">Save</button>
<h1>Canvas:</h1>
<canvas id="svg-canvas"></canvas>
<script>
...
$('#save').click(myFunction);
function myFunction() {
d3.selectAll("path").attr("fill", "none");
d3.selectAll(".tick line, path.domain").attr("stroke", "black");
var $container = $('#chart'),
// Canvg requires trimmed content
content = $container.html().trim(),
canvas = document.getElementById('svg-canvas');
// Draw svg on canvas
canvg(canvas, content);
}
</script>
