PROGRAM:
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.
