\section dcmmkcrv_synopsis SYNOPSIS
\verbatim
dcmmkcrv [options] dcmfile-in curvedata-in dcmfile-out
\endverbatim
\section dcmmkcrv_description DESCRIPTION
The \b dcmmkcrv utility allows one to create DICOM images containing curve data.
Since curve data is hardly used by vendors today, this is intended as a
means to test implementations that can read curve data. The utility reads an
existing DICOM image and a text file containing the curve data in textual
form. A DICOM curve data repeating group is created according to the
options specified on the command line, added to the existing image and
written back to file. The output file is encoded with the same transfer
syntax used for the input file. This utility only supports the creation of
two-dimensional curves.
\section dcmmkcrv_parameters PARAMETERS

dcmfile-in DICOM input image file
curvedata-in curve data input file (text)
dcmfile-out DICOM output filename

\section dcmmkcrv_notes NOTES
\subsection dcmmkcrv_syntax_data_file Syntax of the Curve Data File
The curve data file is expected to be a plain ASCII text file containing
numbers (integer or floating point) comprising the values of the point
coordinates. Numbers must be separated by whitespace. No checking of the
value range or value range conversion is performed. Example:
\verbatim
256.451947 1.000000
477.689863 128.822080
128.822080 477.689863
35.310137 128.822080
256.451947 1.000000
\endverbatim
\section dcmmkcrv_logging 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 \e --verbose also
informational messages like processing details are reported. Option
\e --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
\e --log-level. In \e --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 \e --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 \/logger.cfg.
\section dcmmkcrv_command_line 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
\/dumppat.txt).
\section dcmmkcrv_environment ENVIRONMENT
The \b dcmmkcrv utility will attempt to load DICOM data dictionaries specified
in the \e DCMDICTPATH environment variable. By default, i.e. if the
\e DCMDICTPATH environment variable is not set, the file
\/dicom.dic will be loaded unless the dictionary is built
into the application (default for Windows).
The default behavior should be preferred and the \e DCMDICTPATH environment
variable only used when alternative data dictionaries are required. The
\e DCMDICTPATH environment variable has the same format as the Unix shell
\e 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 \e DCMDICTPATH environment variable.
It is an error if no data dictionary can be loaded.
