Group: QImageEncoderSettings is part of multimedia, multimedia_camera
Detailed Description▲
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);See Also▲

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▲
QVariant QImageEncoderSettings::encodingOption(const QString &option) const▲
QVariantMap QImageEncoderSettings::encodingOptions() const▲
Returns the all the encoding options as QVariantMap.

See also encodingOption(), setEncodingOptions()
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.
QMultimedia::EncodingQuality QImageEncoderSettings::quality() const▲
QSize QImageEncoderSettings::resolution() const▲
void QImageEncoderSettings::setCodec(const QString &codec)▲
void QImageEncoderSettings::setEncodingOption(const QString &option, const QVariant &value)▲
Set the encoding option value.
The supported set and meaning of encoding options are system and selected codec specific.

void QImageEncoderSettings::setEncodingOptions(const QVariantMap &options)▲
Replace all the encoding options with options.
The supported set and meaning of encoding options are system and selected codec specific.

void QImageEncoderSettings::setQuality(QMultimedia::EncodingQuality 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.
