20Description
21===========
22
23These four pixel formats are packed raw sRGB / Bayer formats with 14
24bits per colour. Every four consecutive samples are packed into seven
25bytes. Each of the first four bytes contain the eight high order bits
26of the pixels, and the three following bytes contains the six least
27significants bits of each pixel, in the same order.
28
29Each n-pixel row contains n/2 green samples and n/2 blue or red samples,
30with alternating green-red and green-blue rows. They are conventionally
31described as GRGR... BGBG..., RGRG... GBGB..., etc. Below is an example
32of one of these formats:
