15 \section description DESCRIPTION
16 
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
20 formula:
21 
22 \verbatim
23  L = La + L0 * 10^(-D)
24 \endverbatim
25 
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
30 luminance.

41 
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.
