\brief The QImageEncoderSettings class provides a set of image encoder

\since 1.0
|

A image encoder settings object is used to specify the image encoder
|

settings used by QCameraImageCapture. Image encoder settings are selected
|
||||
by constructing a QImageEncoderSettings object, setting the desired
|
||||
properties and then passing it to a QCameraImageCapture instance using the
|
||||
QCameraImageCapture::setImageSettings() function.
