PROGRAM:

NAME


dcmdspfn - Export standard display curves to a text file

SYNOPSIS


dcmdspfn [options]

DESCRIPTION


Command line program converts a DCMTK monitor / camera / printer / scanner characteristics
file to tabbed text file describing the characteristic curve (CC), the display function
and the post-standardized curve (PSC) for an 8 bit display. The 256 values of each curve
can be visualized by a common spread sheet program. Above that the display curve (without
CC and PSC) can also be computed for a specified luminance/OD range (min/max) and a
certain number of Digital Driving Levels (DDL).

PARAMETERS


dcmfile-in DICOM input filename to be dumped

OPTIONS


general options
-h --help
print this help text and exit

--version
print version information and exit

--arguments
print expanded command line arguments

-q --quiet

-d --debug
debug mode, print debug information

-ll --log-level [l]evel: string constant
(fatal, error, warn, info, debug, trace)

+Il --lum-range [m]in max: float
minimum and maximum luminance (cd/m^2)

+Io --od-range [m]in max: float
minimum and maximum optical density (OD),
automatically converted to luminance

creation options
+Ca --ambient-light [a]mbient light: float
ambient light value (cd/m^2, default: file f)

output options
+Og --gsdf [f]ilename: string
write GSDF curve data to file f

+Oc --cielab [f]ilename: string
write CIELAB curve data to file f

NOTES


The output file describing the CC, GSDF or CIELAB and PSC for an 8 bit display system
(monitor, camera, printer or scanner) is a simple text file. Lines starting with a '#' are
treated as comments and, therefore, skipped as well as blank lines. An input file can for
instance be created by the command line tool dconvlum.

The ambient light value possibly defined in the characteristics file is also used for the
calculation. In this case the value is part of the file comment header as well as the
number of DDL (digital driving level) values, the absolute luminance range (measured in
candela per square meter) and the range of the JND index (just noticeable difference) in
case of GSDF. Alternatively, the ambient light value can be specified as a command line
option. When setting the two luminance values instead of reading a monitor characteristic
file as input the luminance range is linearly divided by the number of DDLs.

For printers and scanners the illumination can be specified in addition to the reflected
ambient light (both in the characteristics file and on the command line). The header of
the output file includes the minimum and maximum Optical Density (OD) instead of the
luminance range. Please note that the OD values in the input file have to be ordered in
descending order (in contrast to the luminance values used for monitors and cameras). The
DDL value 0 always means black (darkest value) and the maximum DDL value means white
(brightest value, clear film).

The data folder contains sample characteristics file for monitors, cameras, printers and
scanners. See DICOM standard part 14 for more details on display calibration and Barten's
model (including GSDF).

LOGGING


The level of logging output of the various command line tools and underlying libraries can
be specified by the user. By default, only errors and warnings are written to the standard
error stream. Using option --verbose also informational messages like processing details
are reported. Option --debug can be used to get more details on the internal activity,
e.g. for debugging purposes. Other logging levels can be selected using option --log-
level. In --quiet mode only fatal errors are reported. In such very severe error events,
the application will usually terminate. For more details on the different logging levels,
see documentation of module 'oflog'.

In case the logging output should be written to file (optionally with logfile rotation),
to syslog (Unix) or the event log (Windows) option --log-config can be used. This
configuration file also allows for directing only certain messages to a particular output
stream and for filtering certain messages based on the module or application where they
are generated. An example configuration file is provided in <etcdir>/logger.cfg.

COMMAND LINE


All command line tools use the following notation for parameters: square brackets enclose
optional values (0-1), three trailing dots indicate that multiple values are allowed
(1-n), a combination of both means 0 to n values.

Command line options are distinguished from parameters by a leading '+' or '-' sign,
respectively. Usually, order and position of command line options are arbitrary (i.e. they
can appear anywhere). However, if options are mutually exclusive the rightmost appearance
is used. This behavior conforms to the standard evaluation rules of common Unix shells.

In addition, one or more command files can be specified using an '@' sign as a prefix to
the filename (e.g. @command.txt). Such a command argument is replaced by the content of
the corresponding text file (multiple whitespaces are treated as a single separator unless
they appear between two quotation marks) prior to any further evaluation. Please note that
a command file cannot contain another command file. This simple but effective approach
allows one to summarize common combinations of options/parameters and avoids longish and
confusing command lines (an example is provided in file <datadir>/dumppat.txt).
