NAME
dcmmkcrv - Add 2D curve data to image
SYNOPSIS
dcmmkcrv [options] dcmimg-in curvedata-in dcmimg-out
DESCRIPTION
The dcmmkcrv utility allows 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.

-a --axis x: string, y: string
set Axis Units to xy (default: absent)
NOTES
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:
256.451947 1.000000
477.689863 128.822080
128.822080 477.689863
35.310137 128.822080
256.451947 1.000000
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) 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
share/data/dumppat.txt).
ENVIRONMENT
The dcmmkcrv 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
<PREFIX>/lib/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.
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.
