NAME
       dcmdjpls	- Decode JPEG-LS compressed DICOM file

SYNOPSIS
       dcmdjpls	[options] dcmfile-in dcmfile-out

DESCRIPTION
       The  dcmdjpls  utility reads a JPEG-ls compressed DICOM image (dcmfile-
       in), decompresses the JPEG-LS data (i. e. conversion to a native	 DICOM
       transfer	 syntax)  and  writes  the  converted  image to	an output file
       (dcmfile-out).

PARAMETERS
       dcmfile-in   DICOM input	filename to be converted

       dcmfile-out  DICOM output filename

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
		quiet mode, print no warnings and errors

	 -v   --verbose
		verbose	mode, print processing details

	 -d   --debug
		debug mode, print debug	information

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

	 -lc  --log-config  [f]ilename:	string
		use config file	f for the logger

   input options
       input file format:

	 +f   --read-file
		read file format or data set (default)

	 +fo  --read-file-only
		read file format only

	 -f   --read-dataset
		read data set without file meta	information

	 # This	option allows to decompress JPEG-LS compressed DICOM objects that have
	 # been	stored as dataset without meta-header. Such a thing should not exist
	 # since the transfer syntax cannot be reliably	determined without meta-header,
	 # but unfortunately it	does.

   processing options
       planar configuration:

	 +pr  --planar-restore
		restore	original planar	configuration (default)

	 # If the compressed image is a	color image, restore the planar
	 # configuration as described in the Planar Configuration attribute.

	 +pa  --planar-auto
		automatically determine	planar configuration
		from SOP class and color space

	 # If the compressed image is a	color image, store in color-by-plane
	 # planar configuration	if required by the SOP class and photometric
	 # interpretation. Hardcopy Color images are always stored color-by-
	 # plane, and the revised Ultrasound image objects are stored color-by-
	 # plane if the	color model is YBR_FULL.  Everything else is stored
	 # color-by-pixel.

	 +px  --color-by-pixel
		always store color-by-pixel

	 # If the compressed image is a	color image, store in color-by-pixel
	 # planar configuration.

	 +pl  --color-by-plane
		always store color-by-plane

	 # If the compressed image is a	color image, store in color-by-plane
	 # planar configuration.

       SOP Instance UID:

	 +ud  --uid-default
		keep same SOP Instance UID (default)

	 #  Never assigns a new	SOP instance UID.

	 +ua  --uid-always
		always assign new UID

	 # Always assigns a new	SOP instance UID.

       other processing	options:

	 +io  --ignore-offsettable
		ignore offset table when decompressing

   output options
       output file format:

	 +F   --write-file
		write file format (default)

	 -F   --write-dataset
		write data set without file meta information

       output transfer syntax:

	 +te  --write-xfer-little
		write with explicit VR little endian (default)

	 +tb  --write-xfer-big
		write with explicit VR big endian TS

	 +ti  --write-xfer-implicit
		write with implicit VR little endian TS

       post-1993 value representations:

	 +u   --enable-new-vr
		enable support for new VRs (UN/UT) (default)

		disable	support	for new	VRs, convert to	OB

       group length encoding:

	 +g=  --group-length-recalc
		recalculate group lengths if present (default)

	 +g   --group-length-create
		always write with group	length elements

	 -g   --group-length-remove
		always write without group length elements

       length encoding in sequences and	items:

	 +e   --length-explicit
		write with explicit lengths (default)

	 -e   --length-undefined
		write with undefined lengths

       data set	trailing padding (not with --write-dataset):

	 -p=  --padding-retain
		do not change padding (default if not --write-dataset)

	 -p   --padding-off
		no padding (implicit if	--write-dataset)

	 +p   --padding-create	[f]ile-pad [i]tem-pad: integer
		align file on multiple of f bytes
		and items on multiple of i bytes

       LittleEndianImplicitTransferSyntax	      1.2.840.10008.1.2
       LittleEndianExplicitTransferSyntax	      1.2.840.10008.1.2.1
       BigEndianExplicitTransferSyntax		      1.2.840.10008.1.2.2

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  dcmdjpls  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.
