       dcmmkcrv	- Add 2D curve data to image

       dcmmkcrv	[options] dcmfile-in curvedata-in dcmfile-out

       The 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.

   curve creation options
       curve type:

	 +r  --roi
	       create as ROI curve

       curve value representation:

	 +v  --data-vr	[n]umber: integer 0..4 (default: 4)
	       select curve data VR: 0=US, 1=SS, 2=FL, 3=FD, 4=SL

	 -c  --curve-vr	 [n]umber: integer 0..2	(default: 0)
	       select VR with which the	Curve Data element is written
	       0=VR according to --data-vr, 1=OB, 2=OW

       repeating group:

	 -g  --group  [n]umber:	integer	0..15 (default:	0)
	       select repeating	group: 0=0x5000, 1=0x5002 etc.

       curve description:

	 -l  --label  s: string
	       set Curve Label to s (default: absent)

	 +d  --description  s: string
	       set Curve Description to	s (default: absent)

	 -a  --axis  x:	string,	y: string
	       set Axis	Units to xy (default: absent)

   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.

       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

       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

       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).

       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
       _datadir_/dicom.dic  will be loaded unless the dictionary is built into
       the application (default	for Windows).

       The  default  behavior  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.
