       dcmp2pgm - Read DICOM image and presentation state and render bitmap


       dcmp2pgm [options] dcmimage-in [bitmap-out]


       The  dcmp2pgm  utility  renders  a monochrome DICOM image under the control of a grayscale
       softcopy presentation state object into a monochrome bitmap with 8 bits/pixel. The  bitmap
       is  stored  either  as  'Portable  Gray  Map'  (PGM) or as a DICOM secondary capture image
       object. If no presentation state is read  from  file,  a  default  presentation  state  is
       created.  The  utility  allows  to  read a configuration file of the Softcopy Presentation
       State Viewer upon startup.  In  this  case,  the  settings  from  the  configuration  file
       affecting  the rendering of the presentation state are used, e.g. a correction of the gray
       scale range according  to  Barten's  model  (DICOM  part  14)  can  be  performed  if  the
       characteristic  curve  of the display system is available and defined in the configuration


       dcmimage-in  input DICOM image

       bitmap-out   output DICOM image or PGM bitmap

       Please note that the dcmp2pgm tool does not render all aspects that  are  defined  by  the
       Grayscale  Softcopy  Presentation State (GSPS) object but only those that are supported by
       the underlying DCMTK classes. In particular, textual and graphical annotations will not be
       visible  in  the  output  image.  The  reason  is  that these aspects of a GSPS object are
       typically rendered by DICOMscope, the graphical user interface that is put on top  of  the
       related DCMTK classes and written in Java.

       Also  concepts  that  were  introduced  after  the initial definition of the GSPS IOD (see
       Supplement 33) are ignored. This includes Supplement 120 with its extended  features  like
       e.g. Compound Graphics.


       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  dcmp2pgm  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.
