dcmpsmk: Create DICOM grayscale softcopy presentation state

SYNOPSIS

dcmpsmk [options] dcmfile-in dcmfile-out

DESCRIPTION

The dcmpsmk utility reads a DICOM image file and creates a grayscale softcopy presentation state object according to Supplement 33. The presentation state object is written back to file. A number of command line options allow one to specify how certain constructs that might be present in the image file should be referenced or activated in the presentation state. The newly created presentation state references the source image and contains values that should allow for a "reasonable" display of the image when rendered under control of the presentation state.

PARAMETERS

dcmfile-in   DICOM image file(s) to be read ("-" for stdin)

dcmfile-out  DICOM presentation state file to be created ("-" for stdout)

-lx --location-none: image reference without location (default)
-ln --location-network [a]etitle: string: image located at application entity a
-lm --location-media [f]ilesetID, fileset[UID]: string: image located on storage medium

validation options

--validate-std: images referenced by GSPS must belong to the same SOP class (default)
--validate-related: images referenced by GSPS may belong to related 'for presentation' and 'for processing' SOP class
--validate-relaxed: images referenced by GSPS may be any SOP class

output options

+t= --write-xfer-same: write with same TS as image file (default)
+te --write-xfer-little: write with explicit VR little endian TS
+tb --write-xfer-big: write with explicit VR big endian TS
+ti --write-xfer-implicit: write with implicit VR little endian TS

NOTES

If more than one input file (dcmfile-in) is specified, the additional image files are only referenced from the created presentation state file, but no further (e.g. display-related) information is taken over.

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 dcmpsmk 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.
