DICODE

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.

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

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

-i item Select input item number.

INPUT ITEMS

11.xx Any coefficient item
