  I don't know your backend or scanner but these options may be inactive
  because of the mode you chose. Options can depend on each other. So e.g. for
  most Mustek scanners "brightness" is only active in lineart mode. Try to set
  the mode you want to use before the "--help" option.

  Bye,
  Henning
