<h2>Detailed Description</h2>
<p>The AnimatedImage element extends the features of the <a href="qml-image.html">Image</a> element, providing a way to play animations stored as images containing a series of frames, such as those stored in GIF files.</p>
<p>Information about the current frame and totla length of the animation can be obtained using the <a href="qml-animatedimage.html#currentFrame-prop">currentFrame</a> and <a href="qml-animatedimage.html#frameCount-prop">frameCount</a> properties. You can start, pause and stop the animation by changing the values of the <a href="qml-animatedimage.html#playing-prop">playing</a> and <a href="qml-animatedimage.html#paused-prop">paused</a> properties.</p>
<p>The full list of supported formats can be determined with <a href="qmovie.html#supportedFormats">QMovie::supportedFormats()</a>.</p>
<a name="example-usage"></a>
<h2>Example Usage</h2>
<div style="float: left; margin-right: 2em"><p class="centerAlign"><img src="images/animatedimageitem.gif" alt="" /></p></div><p>The following QML shows how to display an animated image and obtain information about its state, such as the current frame and total number of frames. The result is an animated image with a simple progress indicator underneath it.</p>

The default value is false, causing the user interface thread to block while the image is loaded. Setting <i>asynchronous</i> to true is useful where maintaining a responsive user interface is more desirable than having images immediately visible.</p>
<p>Note that this property is only valid for images read from the local filesystem. Images loaded via a network resource (e.g. HTTP) are always loaded asynchonously.</p>
</div></div><!-- @@@asynchronous -->

<!-- $$$cache -->

The default value is true. Setting <i>cache</i> to false is useful when dealing with large images, to make sure that they aren't cached at the expense of small 'ui element' images.</p>
<p>This property group was introduced in QtQuick 1.1.</p>

<br/>
<!-- $$$currentFrame -->

By monitoring this property for changes, you can animate other items at the same time as the image.</p>
<p><a href="qml-animatedimage.html#frameCount-prop">frameCount</a> is the number of frames in the animation. For some animation formats, <a href="qml-animatedimage.html#frameCount-prop">frameCount</a> is unknown and has a value of zero.</p>

<!-- $$$mirror -->

<p>The default value is false.</p>
