NAME

6       dcod2lum  -  Convert  hardcopy  characteristic  curve  file to softcopy
7       format

SYNOPSIS

11       dcod2lum in-file out-file
12

DESCRIPTION

14       Command line program that converts a hardcopy characteristic curve file
15       to  softcopy  format. In other words, the measured optical density (OD)
16       values from the input file  are  transformed  to  the  luminance  space
17       according to the formula:
18
19         L = La + L0 * 10^(-D)
20
21       where  L  is the resulting luminance, La is the reflected ambient light
22       and L0 the illumination (both measured  in  cd/m^2),  'D'  the  optical
23       density (OD). Please note that if no illumination value is specified in
24       the input file (keyword lum) all optical density values are mapped to a
25       constant luminance.

PARAMETERS

28       in-file   hardcopy characteristic curve file to be converted
29
30       out-file  softcopy characteristic curve file to be written
31

NOTES

33       The format of both input and output file is described the documentation
34       of the dcmdspfn  command  line  tool.  In  addition,  the  data  folder
35       contains  sample  characteristics  file monitors, cameras, printers and
36       scanners.
