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 querying supported image codecs and resolutions.

The interface name of QImageEncoderControl is "com.copperspice.CS.imageencodercontrol/1.0" as defined in QImageEncoderControl_iid.

See also: QImageEncoderSettings, QMediaService::requestControl()

Constructor & Destructor Documentation

QImageEncoderControl::~QImageEncoderControl ( )

virtual

Destroys the image encoder control.

QImageEncoderControl::QImageEncoderControl ( QObject * parent = nullptr )

explicitprotected

Constructs a new image encoder control object with the given parent.

Method Documentation

QString QImageEncoderControl::imageCodecDescription ( const QString & codecName ) const

pure virtual

Returns a description of an image codecName.

QImageEncoderSettings QImageEncoderControl::imageSettings ( ) const

pure virtual

Returns the currently used image encoder settings.

The returned value from this method may be different from what was passed to setImageSettings(). This can occur if the settings contained parameters which had default or undefined values.

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 = `nullptr`
	)		const

pure virtual

Returns a list of supported resolutions. If settings is passed, the list which is returned is filtered to only contain resolutions supported with the given settings. The methods 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.
