Every four consecutive samples are packed into seven +bytes. Each of the first four bytes contain the eight high order bits +of the pixels, and the three following bytes contains the six least +significants bits of each pixel, in the same order. + +Each n-pixel row contains n/2 green samples and n/2 blue or red samples, +with alternating green-red and green-blue rows. They are conventionally +described as GRGR... BGBG..., RGRG... GBGB..., etc. Below is an example +of one of these formats: + +**Byte Order.** +Each cell is one byte. + +.. raw:: latex + + \footnotesize + +.. tabularcolumns:: |p{1.8cm}|p{1.0cm}|p{1.0cm}|p{1.0cm}|p{1.1cm}|p{3.3cm}|p{3.3cm}|p{3.3cm}| + +.. flat-table:: + :header-rows: 0 + :stub-columns: 0 + :widths: 2 1 1 1 1 3 3 3 + + + - .. row 1 + + - start + 0 + + - B\ :sub:`00high` + + - G\ :sub:`01high` + + - B\ :sub:`02high` + + - G\ :sub:`03high` + + - G\ :sub:`01low bits 1--0`\ (bits 7--6) + + B\ :sub:`00low bits 5--0`\ (bits 5--0) + + - R\ :sub:`02low bits 3--0`\ (bits 7--4) + + G\ :sub:`01low bits 5--2`\ (bits 3--0) + + - G\ :sub:`03low bits 5--0`\ (bits 7--2) + + R\ :sub:`02low bits 5--4`\ (bits 1--0) + + - .. row 2 + + - start + 7 + + - G\ :sub:`00high` + + - R\ :sub:`01high` + + - G\ :sub:`02high` + + - R\ :sub:`03high` + + - R\ :sub:`01low bits 1--0`\ (bits 7--6) + + G\ :sub:`00low bits 5--0`\ (bits 5--0) + + - G\ :sub:`02low bits 3--0`\ (bits 7--4) + + R\ :sub:`01low bits 5--2`\ (bits 3--0) + + - R\ :sub:`03low bits 5--0`\ (bits 7--2) + + G\ :sub:`02low bits 5--4`\ (bits 1--0) + + - .. row 3 + + - start + 14 + + - B\ :sub:`20high` + + - G\ :sub:`21high` + + - B\ :sub:`22high` + + - G\ :sub:`23high` + + - G\ :sub:`21low bits 1--0`\ (bits 7--6) + + B\ :sub:`20low bits 5--0`\ (bits 5--0) + + - R\ :sub:`22low bits 3--0`\ (bits 7--4) + + G\ :sub:`21low bits 5--2`\ (bits 3--0) + + - G\ :sub:`23low bits 5--0`\ (bits 7--2) + + R\ :sub:`22low bits 5--4`\ (bits 1--0) + + - .. row 4 + + - start + 21 + + - G\ :sub:`30high` + + - R\ :sub:`31high` + + - G\ :sub:`32high` + + - R\ :sub:`33high` + + - R\ :sub:`31low bits 1--0`\ (bits 7--6) + G\ :sub:`30low bits 5--0`\ (bits 5--0) + + - G\ :sub:`32low bits 3--0`\ (bits 7--4) + R\ :sub:`31low bits 5--2`\ (bits 3--0) + + - R\ :sub:`33low bits 5--0`\ (bits 7--2) + G\ :sub:`32low bits 5--4`\ (bits 1--0) + +.. raw:: latex + + \normalsize + |
