dctopnm

DCTOPNM(1)						DICOM PS3 - DICOM image to PNM file						DCTOPNM(1)

NAME

       dctopnm - ACR/NEMA DICOM PS3 ... DICOM PS3 - DICOM image to PNM file

SYNOPSIS

       dctopnm [ -v|verbose ] [ -quiet|silent ]

DESCRIPTION

       dctopnm reads the named dicom or acr-nema input file and copies the raw image pixel data to a PNM file after adding a PGM or PPM header.

       The  input  file  must  be  unencapsulated, and in the case of > 8 bit data, in the same byte order as desired in the output, since the raw
       bytes are copied from input to output without any conversion. Use dccp(1) first to change the encoding if necessary.

       Only the necessary number of bytes to encode the pixel data will be written (based on rows, columns, number of frames,  samples	per  pixel
       and  bits  allocated);  this  means that for an odd number of bytes the extra DICOM padding byte will not be copied to the raw output. This
       prevents netpbm utilities freaking out with an error "reading magic number" if the padding  byte  is  present.  If  any	of  the  necessary
       attributes to calculate the correct pixel data length are missing, all encoded bytes will be written.

OPTIONS

       The PNM 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 replace-
	      ment, and before writing.

ENVIRONMENT


EXAMPLES


       % dcfile big.dc3
       Meta: UID      1.2.840.10008.1.2.1
       Meta: Description   "Explicit VR Little Endian"
       Meta: ByteOrder	   Little
       Meta: VR       Explicit
       Meta: Encapsulated  No
       Data: UID      1.2.840.10008.1.2.2
       Data: Description   "Explicit VR Big Endian"
       Data: ByteOrder	   Big
       Data: VR       Explicit
       Data: Encapsulated  No

       % dctopnm big.dc3 big.pgm -endian big
	Rows = 512
	Columns = 512
	NumberOfFrames = 0
	PhotometricInterpretation = MONOCHROME2

	HighBit = 15
	PixelRepresentation = 1
	PlanarConfiguration = 0x0
	Rows*Columns*SamplesPerPixel*BitsAllocated/8 = 0x80000
