178c2ecf20Sopenharmony_ciDescription
188c2ecf20Sopenharmony_ci===========
198c2ecf20Sopenharmony_ci
208c2ecf20Sopenharmony_ciThese four pixel formats are packed raw sRGB / Bayer formats with 12
218c2ecf20Sopenharmony_cibits per colour. Every two consecutive samples are packed into three
228c2ecf20Sopenharmony_cibytes. Each of the first two bytes contain the 8 high order bits of
238c2ecf20Sopenharmony_cithe pixels, and the third byte contains the four least significants
248c2ecf20Sopenharmony_cibits of each pixel, in the same order.
258c2ecf20Sopenharmony_ci
268c2ecf20Sopenharmony_ciEach n-pixel row contains n/2 green samples and n/2 blue or red
278c2ecf20Sopenharmony_cisamples, with alternating green-red and green-blue rows. They are
288c2ecf20Sopenharmony_ciconventionally described as GRGR... BGBG..., RGRG... GBGB..., etc.
