title: Render Highcharts canvas as a PNG on the page
body: <p>I'm using the HighCharts library to generate some dynamic charts. However, I'd like to render the HighCharts canvas element as a PNG image, such that the user can copy and paste the chart into an email, etc. without having to use the exporting function.</p>
  
  <p>Specifically, I'm trying to create an HTML email template that includes the chart, and want the user to be able to select all > copy/paste into their email client instead of copy/pasting, exporting the image, then finding a way to insert it in the email.</p>
  
  <p>I've found this: <a href="https://stackoverflow.com/questions/923885/capture-html-canvas-as-gif-jpg-png-pdf">Capture HTML Canvas as gif/jpg/png/pdf?</a>, but the code doesn't seem to render an image to the document.</p>
