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 * 10ˆ(-D)

       where L is the resulting luminance, La is the reflected  ambient  light
       and  L0  the  illumination  (both  measured in cd/mˆ2), '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 output 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
