  range 0 - 255 to look-up tables that are then used to modify R, G, B values.

      Value is tokenised using semicolon separator into exactly 256 integer 
      values in range 0 - 255 and a look-up table for red channel values is 
      created and applied to image. If tokenising of value fails a linear table 
      that returns input values unchanged is used instead.
