QImageEncoderSettings露

PyQt5.QtMultimedia.QImageEncoderSettings

Description露

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);

Methods露

__init__()

Constructs a null image encoder settings object.

__init__(QImageEncoderSettings)

Constructs a copy of the image encoder settings object other.

codec() → str

Returns the image codec.

See also

setCodec().

encodingOption(str) → Any

Returns the value of encoding option.

See also

setEncodingOption(), encodingOptions().

encodingOptions() → Dict[str, Any]

Returns the all the encoding options as QVariantMap.

See also

encodingOption(), setEncodingOptions().

__eq__(QImageEncoderSettings) → bool

TODO

isNull() → bool

Identifies if a image encoder settings object is uninitalized.

Returns true if the settings are null, and false if they are not.

__ne__(QImageEncoderSettings) → bool

TODO

quality() → EncodingQuality

Returns the image encoding quality.

See also

setQuality().

resolution() → QSize

Returns the resolution of the encoded image.

See also

setResolution().

setCodec(str)

Sets the image codec.

See also

codec().

setEncodingOption(str, Any)

Set the encoding option value.

The supported set and meaning of encoding options are system and selected codec specific.

See also

encodingOption(), setEncodingOptions().

setEncodingOptions(Dict[str, Any])

Replace all the encoding options with options.

The supported set and meaning of encoding options are system and selected codec specific.

See also

encodingOptions(), encodingOption(), setEncodingOption().

setQuality(EncodingQuality)

TODO

setResolution(QSize)

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().

setResolution(int, int)

Sets the width and height of the resolution of the encoded image.

This is an overloaded function.
