18 | 12-bit Bayer formats expanded to 16 bits | |

20 | ||
21 | Description | |
22 | =========== | |
23 | ||
24 | These four pixel formats are raw sRGB / Bayer formats with 12 bits per | |
25 | colour. Each colour component is stored in a 16-bit word, with 4 unused | |
26 | high bits filled with zeros. Each n-pixel row contains n/2 green samples | |
27 | and n/2 blue or red samples, with alternating red and blue rows. Bytes | |
28 | are stored in memory in little endian order. They are conventionally | |
29 | described as GRGR... BGBG..., RGRG... GBGB..., etc. Below is an example | |
30 | of one of these formats | |

33 | Each cell is one byte, high 6 bits in high bytes are 0. |
