Detailed Description
The QImageEncoderSettings class provides a set of image encoder settings.
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.
QImageEncoderSettings imageSettings;
imageSettings.setCodec("image/jpeg");
imageSettings.setResolution(1600, 1200);
imageCapture->setEncodingSettings(imageSettings);
Member Function Documentation
QImageEncoderSettings::QImageEncoderSettings ()
Constructs a null image encoder settings object.
QImageEncoderSettings::QImageEncoderSettings ( const QImageEncoderSettings & other )
Constructs a copy of the image encoder settings object other.
QImageEncoderSettings::~QImageEncoderSettings ()
Destroys a image encoder settings object.
QString QImageEncoderSettings::codec () const
Returns the image codec.
See also setCodec().
bool QImageEncoderSettings::isNull () const
Identifies if a image encoder settings object is uninitalized.
Returns true if the settings are null, and false if they are not.
Returns the image encoding quality.
See also setQuality().
QSize QImageEncoderSettings::resolution () const
Returns the resolution of the encoded image.
See also setResolution().
void QImageEncoderSettings::setCodec ( const QString & codec )
Sets the image codec.
See also codec().
Sets the image encoding quality.
See also quality().
void QImageEncoderSettings::setResolution ( const QSize & resolution )
Sets the resolution of the encoded image.
An empty QSize indicates the encoder should make an optimal choice based on what is available from the image source and the limitations of the codec.
See also resolution().
void QImageEncoderSettings::setResolution ( int width, int height )
Sets the width and height of the resolution of the encoded image.
This is an overloaded function.
bool QImageEncoderSettings::operator!= ( const QImageEncoderSettings & other ) const
Determines if other is of equal value to a image encoder settings object.
Returns true if the settings objects are not of equal value, and false if they are of equal value.
QImageEncoderSettings & QImageEncoderSettings::operator= ( const QImageEncoderSettings & other )
Assigns the value of other to a image encoder settings object.
bool QImageEncoderSettings::operator== ( const QImageEncoderSettings & other ) const
Determines if other is of equal value to a image encoder settings object.
Returns true if the settings objects are of equal value, and false if they are not of equal value.
