  14 Description
  15 ===========
  16
  17 In this format each four bytes is two pixels. Each four bytes is two
  18 Y's, a Cb and a Cr. Each Y goes to one of the pixels, and the Cb and Cr
  19 belong to both pixels. As you can see, the Cr and Cb components have
  20 half the horizontal resolution of the Y component.

  22 **Byte Order.**
  23 Each cell is one byte.
