}Property Documentation▲
[since 6.7] correctionAngle : QtVideo::Rotation▲
Returns the rotation angle needed to compensate for the physical camera rotation of the camera compared to its native orientation. In other words, the property represents the clockwise angle through which the output image needs to be rotated to be upright on the device screen in its native orientation. Since correctionAngle is relative to the native orientation, this value does not change with altering the device orientation (portrait/landscape). The correction angle may be non-zero mostly on Android, where native and camera orientations are defined by the manufacturer.
This property was introduced in Qt 6.7.
