NAME

       dcmconv - Convert DICOM file encoding

SYNOPSIS

       dcmconv [options] dcmfile-in dcmfile-out

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  behavior  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 one 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 dcmconv 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.
