## Discussion

\abstract Indicates a relative shift of the left and right images, which changes the zero parallax plane.
\discussion The value encoded in normalized image space is a CFNumber holding a signed 32-bit integer measured over the range of -10000 to 10000 mapping to the uniform range [-1.0…1.0]. The interval of 0.0 to 1.0 or 0 to 10000 maps onto the stereo eye view image width. The negative interval 0.0 to -1.0 or 0 to -10000 similarly map onto the stereo eye view image width.
The default value of 0 is inferred if this property is not set.
