Every two consecutive samples are packed into three22bytes. Each of the first two bytes contain the 8 high order bits of23the pixels, and the third byte contains the four least significants24bits of each pixel, in the same order.25 26Each n-pixel row contains n/2 green samples and n/2 blue or red27samples, with alternating green-red and green-blue rows. They are28conventionally described as GRGR... BGBG..., RGRG...
