In PixelLive SDK,a pixel layout is defined by a Photometric value. Usually you don't have to know the details of Photometric definition since Photometric value should be manipulated using PhotometricComponents class.
Anyway, the information described here may be changed in the future versions and you should not write codes depends on them.
