      Decoding

      The decoding of the continuous line count is:

      Clc = Px0Green × 256 + Px0Blue

      Example

      Clc = 217 × 256 + 127 = 55679

      Decoding

      The decoding of the line count is

      Lc = Px1Green × 256 + Px1Blue

      Example

      Lc = 0 × 256 + 0 = 0

      Decoding

      The decoding of the line time is:

      Lt = (Px2Red × 216 + Px2Green × 28 + Px2Blue) / 100

      Example

      Lt = (0 × 216 + 21 × 28 + 124) / 100 = 55 µs
