NAME

       dcmp2pgm - Read DICOM image and presentation state and render bitmap

SYNOPSIS

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

DESCRIPTION

       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
       file.

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 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 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  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 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  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. 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.
