Detailed Description
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 org.qt-project.qt.imageencodercontrol/5.0 as defined in QImageEncoderControl_iid.
Member Function Documentation
QImageEncoderControl::QImageEncoderControl(QObject * parent = 0) [protected]
Constructs a new image encoder control object with the given parent
QImageEncoderControl::~QImageEncoderControl() [virtual]
Destroys the image encoder control.
QString QImageEncoderControl::imageCodecDescription(const QString & codec) const [pure virtual]
Returns a description of an image codec.
QImageEncoderSettings QImageEncoderControl::imageSettings() const [pure virtual]
Returns the currently used image encoder settings.
The returned value may be different tha passed to QImageEncoderControl::setImageSettings() if the settings contains the default or undefined parameters. In this case if the undefined parameters are already resolved, they should be returned.
See also setImageSettings().
void QImageEncoderControl::setImageSettings(const QImageEncoderSettings & settings) [pure virtual]
Sets the selected image encoder settings.
See also imageSettings().
QStringList QImageEncoderControl::supportedImageCodecs() const [pure virtual]
Returns a list of supported image codecs.
QList<QSize> QImageEncoderControl::supportedResolutions(const QImageEncoderSettings & settings, bool * continuous = 0) const [pure virtual]
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.
