NAME¶
dcod2lum - Convert hardcopy characteristic curve file to softcopy format
SYNOPSIS¶
dcod2lum 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.
FILES¶
<datadir>/camera.lut - sample characteristics file of a camera
<datadir>/monitor.lut - sample characteristics file of a monitor
<datadir>/printer.lut - sample characteristics file of a printer
<datadir>/scanner.lut - sample characteristics file of a scanner
