QCameraViewfinderSettings¶

PyQt5.QtMultimedia.QCameraViewfinderSettings

Description¶

The QCameraViewfinderSettings class provides a set of viewfinder settings.

A viewfinder settings object is used to specify the viewfinder settings used by QCamera. Viewfinder settings are selected by constructing a QCameraViewfinderSettings object, setting the desired properties and then passing it to a QCamera instance using the setViewfinderSettings() function.

#     QCameraViewfinderSettings viewfinderSettings;
#     viewfinderSettings.setResolution(640, 480);
#     viewfinderSettings.setMinimumFrameRate(15.0);
#     viewfinderSettings.setMaximumFrameRate(30.0);

#     camera->setViewfinderSettings(viewfinderSettings);

Different cameras may have different capabilities. The application should query the camera capabilities before setting parameters. For example, the application should call supportedViewfinderResolutions() before calling setResolution().
