</p>
<p>
This example shows how to scan any supported 1D/2D code with ZXing javascript library from an image.
The example decodes from the
<code>src</code> in
<code>img</code> tag, however is also possible to decode directly from an url without an
<code>img</code> tag.
</p>
<div>
<a class="button" id="decodeButton">Decode</a>
</div>
<div>
<img id="img" src="../../resources/blackbox/qrcode-3/01.png" style="border: 1px solid gray"></img>
</div>
<label>Result:</label>
<pre><code id="result"></code></pre>
<p>See the <a href="https://github.com/zxing-js/library/tree/master/docs/examples/multi-image/">source code</a> for this example.</p>
