Each colour component is stored in a 16-bit word, with 4 unused +high bits filled with zeros. Each n-pixel row contains n/2 green samples +and n/2 blue or red samples, with alternating red and blue rows. Bytes +are stored in memory in little endian order. 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, high 6 bits in high bytes are 0. + + + +.. flat-table:: + :header-rows: 0 + :stub-columns: 0 + :widths: 2 1 1 1 1 1 1 1 1 + + + - .. row 1 + + - start + 0: + + - B\ :sub:`00low` + + - B\ :sub:`00high` + + - G\ :sub:`01low` + + - G\ :sub:`01high` + + - B\ :sub:`02low` + + - B\ :sub:`02high` + + - G\ :sub:`03low` + + - G\ :sub:`03high` + + - .. row 2 + + - start + 8: + + - G\ :sub:`10low` + + - G\ :sub:`10high` + + - R\ :sub:`11low` + + - R\ :sub:`11high` + + - G\ :sub:`12low` + + - G\ :sub:`12high` + + - R\ :sub:`13low` + + - R\ :sub:`13high` + + - .. row 3 + + - start + 16: + + - B\ :sub:`20low` + + - B\ :sub:`20high` + + - G\ :sub:`21low` + + - G\ :sub:`21high` + + - B\ :sub:`22low` + + - B\ :sub:`22high` + + - G\ :sub:`23low` + + - G\ :sub:`23high` + + - .. row 4 + + - start + 24: + + - G\ :sub:`30low` + + - G\ :sub:`30high` + + - R\ :sub:`31low` + + - R\ :sub:`31high` + + - G\ :sub:`32low` + + - G\ :sub:`32high` + + - R\ :sub:`33low` + + - R\ :sub:`33high` + + + + +.. ------------------------------------------------------------------------------ +..
