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.

This function was introduced in Qt Mobility 1.0.

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.

This function was introduced in Qt Mobility 1.0.

See also setImageSettings().

void QImageEncoderControl::setImageSettings ( const QImageEncoderSettings & settings ) [pure virtual]

Sets the selected image encoder settings.

This function was introduced in Qt Mobility 1.0.

See also imageSettings().

QStringList QImageEncoderControl::supportedImageCodecs () const [pure virtual]

Returns a list of supported image codecs.

This function was introduced in Qt Mobility 1.0.

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.

This function was introduced in Qt Mobility 1.0.
