The QImageEncoderControl class provides access to the settings of a media service that performs image encoding.
If a QMediaService supports encoding image data it will implement QImageEncoderControl. This control allows to set image encoding settings and provides functions for quering supported image codecs and resolutions.
The interface name of QImageEncoderControl is com.nokia.Qt.QImageEncoderControl/1.0 as defined in QImageEncoderControl_iid.
See also QImageEncoderSettings and QMediaService::requestControl().
Constructs a new image encoder control object with the given parent
Destroys the image encoder control.
Returns a description of an image codec.
Returns the currently used image encoder settings.
See also setImageSettings().
Sets the selected image encoder settings.
See also imageSettings().
Returns a list of supported image codecs.
Returns a list of supported resolutions.
If non null image settings parameter is passed, the returned list is reduced to resolutions supported with partial settings applied. It can be used to query the list of resolutions, supported by specific image codec.
If the encoder supports arbitrary resolutions within the supported resolutions range, *continuous is set to true, otherwise *continuous is set to false.
com.nokia.Qt.QImageEncoderControl/1.0
Defines the interface name of the QImageEncoderControl class.
