See the file ../dicom3tools/optin.so.
 
 
See the file ../dicom3tools/binout.so.
 

DESCRIPTION

dctopgm8 reads the named dicom or acr-nema input file, converts it to an 8 bit grayscale image by windowing or application of a VOI LUT and saves it as a PGM file.
In the absence of overriding command line options, the default behavior is to apply the first VOI LUT found, else if none, the first pair of window values in the input file, else if none, the full range of the input pixel values.
The input file must be unencapsulated.

OPTIONS

The PGM output goes where it is specified or standard out. The verbose output goes to standard error.
The basic input switches are described in dcintro(1). Options specific to this program are:
-quiet|silent
Suppress the normal description of image parameters.
-verbose
Display byte offset from file start and message start, in hexadecimal, and dump contents while reading, once read, during replacement, and before writing.
-windowwidth width
The window width to use (also supresses use of any VOI LUT).
-windowlevel|windowcenter center
The window center to use (also supresses use of any VOI LUT).
-ignorewindow
Ignore window center and width values in the input file, and use the full pixel value range instead (if no other command line options).
-voilut numberfromzero
Use the selected VOI LUT from the input file (indexed from 0 not 1).
-ignorevoilut
Ignore any VOI LUTs in the input file, and use the window values or the full pixel value range instead (if no other command line options).
-invertedgray
Invert the grayscale, overriding the PhotometricInterpretation in the input file.
-signed|unsigned
Override the sign specified in the PixelRepresentation in the input file.
