<p>This module allows to print QR in better structure than the standard
odoo.</p>
<p>The original image looks like the following</p>
<p><img alt="image1" src="https://raw.githubusercontent.com/OCA/reporting-engine/18.0/report_qr/static/description/old_qr.png" /></p>
<p>With the new generator, it looks like:</p>

<h2><a class="toc-backref" href="#toc-entry-1">Usage</a></h2>
<p>When creating new reports, you should use a path like the following:</p>
<pre class="literal-block">
&lt;img t-att-src=&quot;'/report/qr/?value=%s&amp;amp;error_correction=%s' % ('HELLO WORLD!', 3)&quot; style=&quot;width:100;height:100&quot;/&gt;
</pre>
<p>The <strong>error_correction</strong> parameter controls the error correction used
for the QR Code. The following four constants are made available:</p>
<ul class="simple">
<li><strong>error_correction</strong> = 1: About 7% or less errors can be corrected.</li>
<li><strong>error_correction</strong> = 0: About 15% or less errors can be corrected.</li>
<li><strong>error_correction</strong> = 3: About 25% or less errors can be corrected.</li>
<li><strong>error_correction</strong> = 2: About 30% or less errors can be corrected.</li>
</ul>
<p>The <strong>box_size</strong> parameter controls how many pixels each “box” of the QR
code is. The default is 3. The <strong>border</strong> parameter controls how many
boxes thick the border should be (the default is 4, which is the minimum
according to the specs).</p>
<p>The <strong>version</strong> parameter is an integer from 1 to 40 that controls the
size of the QR Code (the smallest, version 1, is a 21x21 matrix). Set to
None and use the fit parameter when making the code to determine this
automatically.</p>
<p><strong>fill_color</strong> and <strong>back_color</strong> can change the background and the
painting color of the QR, when using the default image factory.</p>
