title: Form submit a signature captured using SVG
body: <p>I came across an example SVG signature capture by @heycam here:</p>
  
  <p><a href="https://stackoverflow.com/questions/3096470/capture-signature-using-html5-and-ipad">Capture Signature using HTML5 and iPad</a>
  Example: <a href="http://mcc.id.au/2010/signature.html" rel="nofollow noreferrer">http://mcc.id.au/2010/signature.html</a></p>
  
  <p>Much simpler than any previous example I have seen, and it works with mouse <em>and</em> touch!</p>
  
  <p>But how would I submit the result as part of a form?</p>
  
  <p>I think I'd want it submitted as a base64 string but I'm open to other options...</p>
  
  <p>For bonus points... any way to strip the yellow background and line from the submitted data?</p>
  
  <p>Thanks!</p>
