Only one red, green or blue -value is given for each pixel. Missing components must be interpolated -from neighbouring pixels. From left to right the first row consists of a -red and green value, the second row of a green and blue value. This -scheme repeats to the right and down for every two columns and rows. +These four pixel formats are raw sRGB / Bayer formats with 8 bits per +sample. Each sample is stored in a byte. Each n-pixel row contains n/2 +green samples and n/2 blue or red samples, with alternating red and +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. + .. flat-table:: :header-rows: 0 :stub-columns: 0 - :widths: 2 1 1 1 1 - - - - .. row 1 - - - start + 0: - - - R\ :sub:`00` - - - G\ :sub:`01` - - - R\ :sub:`02` - - - G\ :sub:`03` - - - .. row 2 - - - start + 4: - - - G\ :sub:`10` - - - B\ :sub:`11` - - - G\ :sub:`12` - - - B\ :sub:`13` - - - .. row 3 - - - start + 8: - - - R\ :sub:`20` - - - G\ :sub:`21` - - - R\ :sub:`22` - - - G\ :sub:`23` - - - .. row 4 - - - start + 12: - - - G\ :sub:`30` - - - B\ :sub:`31` - - - G\ :sub:`32` - - B\ :sub:`33` + * - start + 0: + - B\ :sub:`00` + - G\ :sub:`01` + - B\ :sub:`02` + - G\ :sub:`03` + * - start + 4: + - G\ :sub:`10` + - R\ :sub:`11` + - G\ :sub:`12` + - R\ :sub:`13` + * - start + 8: + - B\ :sub:`20` + - G\ :sub:`21` + - B\ :sub:`22` + - G\ :sub:`23` + * - start + 12: + - G\ :sub:`30` + - R\ :sub:`31` + - G\ :sub:`32` + - R\ :sub:`33` |
