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

       output transfer syntax:

         +te  --write-xfer-little

       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.
