NAME

       dcmdrle - Decode RLE-compressed DICOM file

SYNOPSIS

       dcmdrle [options] dcmfile-in dcmfile-out

DESCRIPTION

       The  dcmdrle utility reads a RLE-compressed DICOM image (dicomfile-in),
       decompresses the image data (i.e. conversion to a native DICOM transfer
       syntax)  and  writes  the converted image to an output file (dicomfile-
       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

         -v   --verbose
                verbose mode, print processing details

         -d   --debug
                debug mode, print debug information

   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 RLE 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
       SOP Instance UID options:

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

         +ua  --uid-always
                always assign new UID

       RLE byte segment order options:

         +bd   --byte-order-default
                 most significant byte first (default)

         +br   --byte-order-reverse
                 least significant byte first

         # This option allows to decompress RLE compressed DICOM files in which the
         # order of byte segments is encoded in incorrect order. This only affects
         # images with more than one byte per sample.

   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)

         -u   --disable-new-vr
                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

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 dcmdrle 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.
