<div class="descr" id="details">
<p><i>Qt Lottie Animation</i> provides a QML API for rendering graphics and animations that are exported in JSON format by the <a href="https://aescripts.com/bodymovin/" translate="no">Bodymovin</a> plugin for Adobe After Effects.</p>
<h2 id="getting-started">Getting Started</h2>
<p>Import the types using the the following statement:</p>
<pre class="qml" translate="no">

<h2 id="limitations">Limitations</h2>
<p>The implementation follows the <a href="https://github.com/airbnb/lottie-web/tree/master/docs/json" translate="no">master specification for bodymovin</a>. Deviations in exported Bodymovin files compared to the specification are taken into account as much as possible when differences are noticed.</p>
<h3 id="general-limitations">General limitations</h3>
<ul>
<li><code translate="no">precomps</code> are not supported</li>
<li>expressions are not supported</li>
<li>the timeline only supports frame-mode, not time-mode</li>
</ul>
<h3 id="animation-level-limitations">Animation level limitations</h3>

<ul>
<li><code translate="no">assets</code> - reusable text and images</li>

<li>the <code translate="no">star</code> element</li>
