title: Alternative to getimageuri() for google charts calendar
body: <p>I have a calender chart being created using the <code>Google Charts API</code>. I have been looking for a way to print the chart as <code>png</code> and I haven't been able to find a good working answer. </p>
  
  <p>Since <code>getImageURI()</code> is not a method listed for Calendar Charts so I can't use the Printing PNG Charts guidelines on Google Developer either. </p>
  
  <p>Update: </p>
  
  <p>I was able to find <a href="http://www.battlehorse.net/page/topics/charts/save_google_charts_as_image.html" rel="nofollow">this tutorial</a> which has been helpful in downloading the image but the issue is that the filename of the file being downloaded is the image bytecode and the solution offered on <a href="http://greenethumb.com/article/1429/user-friendly-image-saving-from-the-canvas/" rel="nofollow">this page by greenthumb</a> doesn't work properly. Using the package downloaded from CanvasSaver GitHub which was linked to on the greenthumb page, the file downloaded upon clicking the save image button is the <code>saveme.php</code> file and not the actual image. I have tried placing <code>obj_close();</code> before <code>echo $decoded;</code> in <code>saveme.php</code> but that hasn't helped solve the issue either. </p>
  
  <p>All help is greatly appreciated.</p>
