Optionally a command can be executed after the creation of the PDF file\&. .SH "PARAMETERS" .PP .PP .nf dcmfile-in DICOM input filename pdffile-out PDF output filename .fi .PP .SH "OPTIONS" .PP .SS "general options" .PP .nf -h --help print this help text and exit --version print version information and exit --arguments print expanded command line arguments -q --quiet quiet mode, print no warnings and errors -v --verbose verbose mode, print processing details -d --debug 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 .fi .PP .SS "input options" .PP .nf 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 input transfer syntax: -t= --read-xfer-auto use TS recognition (default) -td --read-xfer-detect ignore TS specified in the file meta header -te --read-xfer-little read with explicit VR little endian TS -tb --read-xfer-big read with explicit VR big endian TS -ti --read-xfer-implicit read with implicit VR little endian TS parsing of odd-length attributes: +ao --accept-odd-length accept odd length attributes (default) +ae --assume-even-length assume real length is one byte larger handling of undefined length UN elements: +ui --enable-cp246 read undefined len UN as implicit VR (default) -ui --disable-cp246 read undefined len UN as explicit VR handling of defined length UN elements: -uc --retain-un retain elements as UN (default) +uc --convert-un convert to real VR if known automatic data correction: +dc --enable-correction enable automatic data correction (default) -dc --disable-correction disable automatic data correction bitstream format of deflated input: +bd --bitstream-deflated expect deflated bitstream (default) +bz --bitstream-zlib expect deflated zlib bitstream .fi .PP .SS "execution options" .PP .nf -x --exec [c]ommand: string execute command c after PDF extraction .fi .PP .SH "NOTES" .PP Option \fI--exec\fP 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\&. \fBpdf2dcm\fP will be blocked until the command terminates\&. .SH "LOGGING" .PP 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 \fI--verbose\fP also informational messages like processing details are reported\&. Option \fI--debug\fP can be used to get more details on the internal activity, e\&.g\&. for debugging purposes\&. Other logging levels can be selected using option \fI--log-level\fP\&. In \fI--quiet\fP 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'\&. .PP In case the logging output should be written to file (optionally with logfile rotation), to syslog (Unix) or the event log (Windows) option \fI--log-config\fP 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 \fI/logger\&.cfg\fP\&. .SH "COMMAND LINE" .PP 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\&. .PP 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\&. .PP In addition, one or more command files can be specified using an '@' sign as a prefix to the filename (e\&.g\&. \fI@command\&.txt\fP)\&. 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 \fI/dumppat\&.txt\fP)\&. .SH "ENVIRONMENT" .PP The \fBdcm2pdf\fP utility will attempt to load DICOM data dictionaries specified in the \fIDCMDICTPATH\fP environment variable\&. By default, i\&.e\&. if the \fIDCMDICTPATH\fP environment variable is not set, the file \fI/dicom\&.dic\fP will be loaded unless the dictionary is built into the application (default for Windows)\&. .PP The default behavior should be preferred and the \fIDCMDICTPATH\fP environment variable only used when alternative data dictionaries are required\&. The \fIDCMDICTPATH\fP environment variable has the same format as the Unix shell \fIPATH\fP 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 \fIDCMDICTPATH\fP environment variable\&. It is an error if no data dictionary can be loaded\&. .SH "SEE ALSO" .PP \fBpdf2dcm\fP(1) .SH "COPYRIGHT" .PP Copyright (C) 2007-2014 by OFFIS e\&.V\&., Escherweg 2, 26121 Oldenburg, Germany\&.
