    kQTVRFullRes                                    = 1L << 0,

    kQTVRHalfRes                                    = 1L << 1,

    kQTVRQuarterRes                                 = 1L << 2

};

Constant descriptions

kQTVRFullRes: The full resolution of the image.
kQTVRHalfRes: One-half the full resolution of the image.
kQTVRQuarterRes: One-quarter the full resolution of the image.
