1862306a36Sopenharmony_ci===========
1962306a36Sopenharmony_ci
2062306a36Sopenharmony_ciThese four pixel formats are packed raw sRGB / Bayer formats with 12
2162306a36Sopenharmony_cibits per colour. Every two consecutive samples are packed into three
2262306a36Sopenharmony_cibytes. Each of the first two bytes contain the 8 high order bits of
2362306a36Sopenharmony_cithe pixels, and the third byte contains the four least significants
2462306a36Sopenharmony_cibits of each pixel, in the same order.
2562306a36Sopenharmony_ci
2662306a36Sopenharmony_ciEach n-pixel row contains n/2 green samples and n/2 blue or red
2762306a36Sopenharmony_cisamples, with alternating green-red and green-blue rows. They are
2862306a36Sopenharmony_ciconventionally described as GRGR... BGBG..., RGRG... GBGB..., etc.
