dconvlum - Convert VeriLUM files to DCMTK display files
SYNOPSIS
dconvlum in-file out-file [ambient]
DESCRIPTION
Command line program that converts VeriLUM file with characteristic curve data (CCx_xx.dat) to a format used for the Barten transformation
in this toolkit. VeriLUM is a calibration package from ImageSmiths consisting of a photometer (with serial RS232 connector) and a Windows
NT software.
PARAMETERS
in-file VeriLUM characteristic curve file to be converted
out-file DCMTK display file to be written
ambient ambient light (cd/m^2, floating point value)
NOTES
The output file describing the characteristic curve of a display system (monitor) is a simple text file. Lines starting with a '#' are
treated as comments and therefore skipped as well as blank lines. This conversion program creates such a file automatically (including some
comment lines) by transforming the information stored in the VeriLUM file. The number following the magic word 'max' defines the maximum
DDL value (e.g. 255 for 8 bit displays). This definition is required before the luminance data can be defined. Optionally the ambient light
value can be specified in this file too. The floating point value (in candela per square meter) must follow the word 'amb'. Finally the
luminance values are defined for each corresponding DDL (device driving level) value. The entries do not necessarily have to be ordered or
complete, i.e. there can be less than 'max' + 1 entries. Missing values are calculated by cubic spline interpolation.
See DICOM standard part 14 for more details on display calibration and Barten's model (including GSDF).

dcmp2pgm - Read DICOM image and presentation state and render bitmap
SYNOPSIS
dcmp2pgm [options] dcmimage-in [bitmap-out]
DESCRIPTION
The dcmp2pgm utility renders a monochrome DICOM image under the control of a grayscale softcopy presentation state object into a monochrome
bitmap with 8 bits/pixel. The bitmap is stored either as 'Portable Gray Map' (PGM) or as a DICOM secondary capture image object. If no
presentation state is read from file, a default presentation state is created. The utility allows to read a configuration file of the
Softcopy Presentation State Viewer upon startup. In this case, the settings from the configuration file affecting the rendering of the
presentation state are used, e.g. a correction of the gray scale range according to Barten's model (DICOM part 14) can be performed if the
characteristic curve of the display system is available and defined in the configuration file.

bitmap-out output DICOM image or PGM bitmap

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 behaviour 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 to summarize common combinations of options/parameters and avoids longish and confusing command
lines (an example is provided in file <datadir>/dumppat.txt).
ENVIRONMENT
The dcmp2pgm utility will attempt to load DICOM data dictionaries specified in the DCMDICTPATH environment variable. By default, i.e. if
the DCMDICTPATH environment variable is not set, the file <datadir>/dicom.dic will be loaded unless the dictionary is built into the
application (default for Windows).
The default behaviour should be preferred and the DCMDICTPATH environment variable only used when alternative data dictionaries are
required. The DCMDICTPATH environment variable has the same format as the Unix shell PATH variable in that a colon (':') separates entries.
On Windows systems, a semicolon (';') is used as a separator. The data dictionary code will attempt to load each file specified in the
DCMDICTPATH environment variable. It is an error if no data dictionary can be loaded.
