Each colour component is stored in a 16-bit word, with 4 unused25high bits filled with zeros. Each n-pixel row contains n/2 green samples26and n/2 blue or red samples, with alternating red and blue rows. Bytes27are stored in memory in little endian order. They are conventionally28described as GRGR... BGBG..., RGRG...
