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.

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) 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
share/data/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
<PREFIX>/lib/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.
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.
