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 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.
