dcmp2pgm(1)			  OFFIS	DCMTK			   dcmp2pgm(1)

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.

NOTES
   Limitations
       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.

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  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.
