NAME

     fwc29 ata - Fast Wavelet Packet Compression 2D

SYNOPSIS

     fwc2 [ -Nntap ] [ -Ootap ] [ -crrate ] [ -buffersize ] [ -VT
     ] [ -V ] [ -help -h -? ]

DESCRIPTION

     fwc2 performs very fast wavelet packet based compression  in
     2D. The the header elements are compressed using gzip.
     fwc2 gets both its data and its parameters from command line
     arguments.   These  arguments specify the input, output, the
     compression ratio, the buffer size and verbose printout,  if
     desired.

  Command line arguments
     -N ntap  [stdin]
          Enter the input data set name or file immediately after
          typing -N unless the input is from a pipe in which case
          the -N entry must be omitted.  This input  file  should
          include the complete path name if the file resides in a
          different directory.  Example -N/b/vsp/dummy tells  the
          program to look for file 'dummy' in directory '/b/vsp'.

     -O otap  [stdout]
          Enter the output data  set  name  or  file  immediately
          after typing -O.  This output file is not required when
          piping the output to another process.  The output  data
          set also requires the full path name (see above).

     -cr cr  [15]
          Enter the compression ratio.  For the default value, in
          prestack data we get visually lossless compression.

     -buffer rate  [system buffer size]
          enter the desired I/O buffer size.

     -VT  Enter the command line argument '-VT' to get  run  time
          estimates during execution.

     -V   Enter the command line argument '-V' to get  additional
          printout.

     -? or -h or -help
          Enter the command line argument '-?' or  -h  or   -help
          to  get  online help.  The program terminates after the
          help screen is printed.
