dcod2lum(1) OFFIS DCMTK dcod2lum(1)NAMEdcod2lum - Convert hardcopy characteristic curve file to softcopy
format
SYNOPSISdcod2lum 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 ouput 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.
