  21 Description
  22 ===========
  23
  24 These four pixel formats are raw sRGB / Bayer formats with 12 bits per
  25 colour. Each colour component is stored in a 16-bit word, with 4 unused
  26 high bits filled with zeros. Each n-pixel row contains n/2 green samples
  27 and n/2 blue or red samples, with alternating red and blue rows. Bytes
  28 are stored in memory in little endian order. They are conventionally
  29 described as GRGR... BGBG..., RGRG... GBGB..., etc. Below is an example
  30 of one of these formats

  32 **Byte Order.**
  33 Each cell is one byte, high 6 bits in high bytes are 0.
