  13 Description
  14 ===========
  15
  16 This is a 16-bit format, representing depth data. Each pixel is a
  17 distance to the respective point in the image coordinates. Distance unit
  18 can vary and has to be negotiated with the device separately. Each pixel
  19 is stored in a 16-bit word in the little endian byte order.
  20
  21 **Byte Order.**
  22 Each cell is one byte.
