NAME
       dcmcrle - Encode DICOM file to RLE transfer syntax

SYNOPSIS
       dcmcrle [options] dcmfile-in dcmfile-out


DESCRIPTION
       The  dcmcrle  utility reads an uncompressed DICOM image (dicomfile-in),
       performs RLE compression (i.e.  conversion  to  an  encapsulated  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

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

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

         -e   --length-undefined

       data set trailing padding:

         -p=  --padding-retain
                do not change padding (default)

         -p   --padding-off
                no padding

         +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 dcmcrle 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.
