16Description
17===========
18
19These four pixel formats are packed raw sRGB / Bayer formats with 12
20bits per colour. Every two consecutive samples are packed into three
21bytes. Each of the first two bytes contain the 8 high order bits of
22the pixels, and the third byte contains the four least significants
23bits of each pixel, in the same order.
24
25Each n-pixel row contains n/2 green samples and n/2 blue or red
26samples, with alternating green-red and green-blue rows. They are
27conventionally described as GRGR... BGBG..., RGRG... GBGB..., etc.
