OpenLayers 3 - Custom Image Url
<p>I want to get an image thanks to a custom url, because I send a servlet request to my server.</p>

<p>With OL2, I set <code>this.url</code> in <code>OpenLayers.Layer.WMTS</code> when <code>singleTile</code> was true.</p>

<p>Today in OL3, I created a subclasse of ol.source.Image where I change the method <code>getRequestUrl_</code>
It works fine with the openlayers-debug build, but when I want to make my own custom build of openlayers, I get an error :</p>

<pre><code>Uncaught TypeError: a.jb is not a function
</code></pre>

<p>I guess there is something missing in my own build. I exported ol.Image, maybe ol.ImageBase is missing : <code>No matching symbol found: ol.ImageBase</code></p>

<p>So, if you know a proper way to do it, or explain me where am I wrong.
Thank you !</p>

<p>PS: Do you know if <a href="http://openlayers.org/en/v3.12.1/builder/" rel="nofollow">online-builder</a> of Openlayers will be "online" again ?</p>
