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.
