NAME

6       dcod2lum  -  Convert  hardcopy  characteristic  curve  file to softcopy
7       format
8

SYNOPSIS

10       dcod2lum in-file out-file
11

DESCRIPTION

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

PARAMETERS

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

NOTES

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

FILES
