 1814-bit packed Bayer formats

 21Description
 22===========
 23
 24These four pixel formats are packed raw sRGB / Bayer formats with 14
 25bits per colour. Every four consecutive samples are packed into seven
 26bytes. Each of the first four bytes contain the eight high order bits
 27of the pixels, and the three following bytes contains the six least
 28significant bits of each pixel, in the same order.
 29
 30Each n-pixel row contains n/2 green samples and n/2 blue or red samples,
 31with alternating green-red and green-blue rows. They are conventionally
 32described as GRGR... BGBG..., RGRG... GBGB..., etc. Below is an example
 33of one of these formats:

 36Each cell is one byte.
