Every four consecutive samples are packed into seven +bytes. Each of the first four bytes contain the eight high order bits +of the pixels, and the three following bytes contains the six least +significants bits of each pixel, in the same order. + +Each n-pixel row contains n/2 green samples and n/2 blue or red samples, +with alternating green-red and green-blue rows. They are conventionally +described as GRGR... BGBG..., RGRG...
