title: Google QR code generator has extra whitespace with length
body: <p>I use the Google Chart APIs to generate QR codes in an HTML file used by Google Apps Script:</p>
  
  <pre><code>&lt;img src='https://chart.googleapis.com/chart?chs=150x150&amp;cht=qr&amp;chl=https%3A%2F%2Fdocs.google.com%2Fa%2Fforms%2Fd%2F1c0pS0jHY2O2dtLBddqm9myllAh8Lo8Ej_KyvHCYvxzQ%2Fviewform%3Fentry.936466191%3D&lt;?!= data[6] ?&gt;' alt='QR code' height='150' width='150' /&gt;
  </code></pre>
  
  <p>This worked well, generating QR codes like: <a href="https://i.stack.imgur.com/lXjBw.png" rel="nofollow noreferrer">Good QR Code</a></p>
  
  <p><a href="https://i.stack.imgur.com/lXjBw.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/lXjBw.png" alt="enter image description here"></a></p>
  
  <p>When I added another parameter however, extra whitespace around the QR code appeared, like: <a href="https://i.stack.imgur.com/Zj5iY.png" rel="nofollow noreferrer">Bad QR code</a></p>
  
  <p><a href="https://i.stack.imgur.com/Zj5iY.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/Zj5iY.png" alt="enter image description here"></a></p>
  
  <pre><code>&lt;img src='https://chart.googleapis.com/chart?chs=150x150&amp;cht=qr&amp;chl=https%3A%2F%2Fdocs.google.com%2Fa%2Fforms%2Fd%2F1c0pS0jHY2O2dtLBddqm9myllAh8Lo8Ej_KyvHCYvxzQ%2Fviewform%3Fentry.1155899134%3DCheck%2BIn%2FOut%26entry.936466191%3D&lt;?!= data[6] ?&gt;' alt='QR code' height='150' width='150' /&gt;
  </code></pre>
  
  <p>Other than the extra parameter, there was no change. How could I get rid of the excess whitespace? Thanks for your time.</p>
