NAME
     dicode - convert coefficient items to display items

SYNOPSIS
     dicode (-i item) (-d dbrange) (-n numpixel) file

DESCRIPTION
     dicode performs the rescaling of  spectral  coefficients  so
     that they are in a compact and easily displayed format.  The
     routine reads in the spectral coefficient  data  and  scales
     it.   The  16-level  grey scale is found by linearly scaling
     over the dynamic range from the maximum to dbrange below the
     maximum.  Values below the threshold are set white.

     Options

     -I         Identify the program version.

     -ddbrange  Specify dbrange below maximum (default 50.0).  If
                dbrange  is  zero or negative then maximum avail-
                able range will be used.

     -nnumpixel Specify  height  of  output  display  in   pixels
                (default  is  number of input coefficients). Must
                be less than or equal to number of input  coeffi-
                cients.

     -iitem     Select input item number.

INPUT ITEMS
     11.xx      Any coefficient item

OUTPUT ITEMS
     9          Display item
