<h2>Detailed Description</h2>
<p>The QImageEncoderControl class provides access to the settings of a media service that performs image encoding.</p>
<p>If a <a href="qmediaservice.html">QMediaService</a> supports encoding image data it will implement QImageEncoderControl. This control allows to <a href="qimageencodercontrol.html#setImageSettings">set image encoding settings</a> and provides functions for quering supported image <a href="qimageencodercontrol.html#supportedImageCodecs">codecs</a> and <a href="qimageencodercontrol.html#supportedResolutions">resolutions</a>.</p>
<p>The interface name of QImageEncoderControl is <tt>com.nokia.Qt.QImageEncoderControl/1.0</tt> as defined in <a href="qimageencodercontrol.html#QImageEncoderControl_iid">QImageEncoderControl_iid</a>.</p>
