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
