     17Description
     18===========
     19
     20These four pixel formats are packed raw sRGB / Bayer formats with 12
     21bits per colour. Every two consecutive samples are packed into three
     22bytes. Each of the first two bytes contain the 8 high order bits of
     23the pixels, and the third byte contains the four least significants
     24bits of each pixel, in the same order.
     25
     26Each n-pixel row contains n/2 green samples and n/2 blue or red
     27samples, with alternating green-red and green-blue rows. They are
     28conventionally described as GRGR... BGBG..., RGRG... GBGB..., etc.
