9 \section synopsis SYNOPSIS
12 dcod2lum in-file out-file
15 \section description DESCRIPTION
17 Command line program that converts a hardcopy characteristic curve file to
18 softcopy format. In other words, the measured optical density (OD) values
19 from the input file are transformed to the luminance space according to the
26 where \e L is the resulting luminance, \e La is the reflected ambient light
27 and \e L0 the illumination (both measured in cd/m^2), 'D' the optical density
28 (OD). Please note that if no illumination value is specified in the input
29 file (keyword \e lum) all optical density values are mapped to a constant
32 \section parameters PARAMETERS
35 in-file hardcopy characteristic curve file to be converted
37 out-file softcopy characteristic curve file to be written
42 The format of both input and ouput file is described the documentation of the
43 \b dcmdspfn command line tool. In addition, the \e data folder contains
44 sample characteristics file monitors, cameras, printers and scanners.
