NAME

       dctopgx - ACR/NEMA DICOM PS3 ... DICOM PS3 - DICOM image to PGX file

SYNOPSIS

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

DESCRIPTION

       dctopgx  reads  the  named  dicom or acr-nema single channel (grayscale or palette color; the photometric
       interpretation is not checked) input file and copies the raw image pixel data to a PGX file as  used  for
       the JPEG 2000 Verification Model.

       A  PGX  file  contains  of a single text header line of the form "PG <byte order> [+|-]<bit-depth> <cols>
       <rows> immediately by the raw binary data. There may be 1, 2 or 4 bytes per sample corresponding  to  bit
       depths  from  1  to  32.  Byte order is "LM" (little endian) or "ML" (big endian). The signed or unsigned
       pixel representation is indicated by '+' or '-' character before the bit depth. If the  '+'  is  omitted,
       unsigned is implied.

       The input file must be unencapsulated.

       PGX supports big or little endian byte order in the case of > 8 bit data. The output byte order is always
       in the same as the input, since the raw bytes are copied from input to output without any conversion. Use
       dccp(1) first to change the encoding if necessary.

       PGX  also  supports  signed data, so the Pixel Representation of the input is used to specify whether the
       output is signed or unsigned.

OPTIONS

       The PGX 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.
