  18. <title>Description</title>
  19. <para>These four pixel formats are packed raw sRGB /
  20. Bayer formats with 10 bits per colour. Every four consecutive
  21. colour components are packed into 5 bytes. Each of the first 4
  22. bytes contain the 8 high order bits of the pixels, and the
  23. fifth byte contains the two least significants bits of each
  24. pixel, in the same order.</para>
  25. <para>Each n-pixel row contains n/2 green samples and n/2 blue
  26. or red samples, with alternating green-red and green-blue
  27. rows. They are conventionally described as GRGR... BGBG...,
  28. RGRG... GBGB..., etc. Below is an example of one of these
  29. formats:</para>
