^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 18) ===========
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 19) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 20) These four pixel formats are packed raw sRGB / Bayer formats with 12
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 21) bits per colour. Every two consecutive samples are packed into three
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 22) bytes. Each of the first two bytes contain the 8 high order bits of
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 23) the pixels, and the third byte contains the four least significants
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 24) bits of each pixel, in the same order.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 25) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 26) Each n-pixel row contains n/2 green samples and n/2 blue or red
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 27) samples, with alternating green-red and green-blue rows. They are
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 28) conventionally described as GRGR... BGBG..., RGRG... GBGB..., etc.
