This is the command dcm2pdf that can be run in the OnWorks free hosting provider using one of our multiple free online workstations such as Ubuntu Online, Fedora Online, Windows online emulator or MAC OS online emulator
dcm2pdf - Extract PDF file from DICOM encapsulated PDF
dcm2pdf [options] dcmfile-in pdffile-out
The dcm2pdf utility reads a DICOM file of the Encapsulated PDF Storage SOP Class (dcmfile-
in), extracts the embedded PDF document and writes it to an output file (pdffile-out).
Optionally a command can be executed after the creation of the PDF file.
dcmfile-in DICOM input filename
pdffile-out PDF output filename

print version information and exit
print expanded command line arguments
quiet mode, print no warnings and errors
verbose mode, print processing details
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 file format:
read file format or data set (default)
read file format only
read data set without file meta information
input transfer syntax:
use TS recognition (default)
ignore TS specified in the file meta header

parsing of odd-length attributes:
accept odd length attributes (default)
assume real length is one byte larger
handling of undefined length UN elements:
read undefined len UN as implicit VR (default)
read undefined len UN as explicit VR
handling of defined length UN elements:
retain elements as UN (default)
convert to real VR if known
automatic data correction:
enable automatic data correction (default)
disable automatic data correction
bitstream format of deflated input:
expect deflated bitstream (default)
expect deflated zlib bitstream
-x --exec [c]ommand: string
execute command c after PDF extraction
Option --exec allows for the execution of a certain command line after the creation of the
PDF document. The command line to be executed is passed to this option as a parameter. The
specified command line may contain the placeholder '#f', which will be replaced by the PDF
filename at run time. The specified command line is executed in the foreground, i.e.
pdf2dcm will be blocked until the command terminates.
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.
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).
The dcm2pdf 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.
