<p>The <a href="qimageencodersettings.html">QImageEncoderSettings</a> class provides a set of image encoder settings.</p>
<p>A image encoder settings object is used to specify the image encoder settings used by <a href="qcameraimagecapture.html">QCameraImageCapture</a>. Image encoder settings are selected by constructing a <a href="qimageencodersettings.html">QImageEncoderSettings</a> object, setting the desired properties and then passing it to a <a href="qcameraimagecapture.html">QCameraImageCapture</a> instance using the QCameraImageCapture::setImageSettings() function.</p>
