NAME
       dcmconv - Convert DICOM file encoding

SYNOPSIS
       dcmconv [options] dcmfile-in dcmfile-out

DESCRIPTION
       The dcmconv utility reads a DICOM file (dicomfile-in), performs an
       encoding conversion and writes the converted data to an output file
       (dicomfile-out).

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 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
       <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.
