NAME

    dcod2lum


SYNOPSIS

    dcod2lum in-file out-file


SUMMARY

Command line program 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.

The format of both input and ouput file is described the documentation of the
"dcmdspfn" command line tool.  In addition, the "tests" folder contains a
sample characteristics file for both printers and scanners.
