NAME

       dcod2lum - Convert hardcopy characteristic curve file to softcopy format

SYNOPSIS

       dcod2lum in-file out-file

DESCRIPTION

       Command	line  program  that converts a hardcopy characteristic curve file to softcopy format. In other words, the measured optical density
       (OD) values from the input file are transformed to the luminance space according to the formula:

	 L = La + L0 * 10^(-D)

       where L is the resulting luminance, La is the reflected ambient light and L0 the illumination (both measured in cd/m^2),  'D'  the  optical
       density	(OD). Please note that if no illumination value is specified in the input file (keyword lum) all optical density values are mapped
       to a constant luminance.

PARAMETERS

       in-file	 hardcopy characteristic curve file to be converted

       out-file  softcopy characteristic curve file to be written

NOTES

       The format of both input and ouput file is described the documentation of the dcmdspfn command line tool.  In  addition,  the  data  folder
       contains sample characteristics file monitors, cameras, printers and scanners.

FILES

       <datadir>/camera.lut - sample characteristics file of a camera
       <datadir>/monitor.lut - sample characteristics file of a monitor
       <datadir>/printer.lut - sample characteristics file of a printer
       <datadir>/scanner.lut - sample characteristics file of a scanner
