NAME

       ncarv_spool - spooled device configuration table for interactive metafile translator ictrans

SYNOPSIS

       $NCARG_ROOT/lib/ncarg/ncarv_spool
       ~/.ncarv_spool

DESCRIPTION

       The  ncarv_spool  file  contains  definitions for spooled devices to be used by ictrans.  Each definition
       describes a rule used for sending a set of metafile frames to a spooled device.

       Each entry consists of a line of the form:

              alias_name : translator_args : filter_chain

       alias_name          an identifier unique to the file. It is the alias by  which  the  definition  may  be
                           referenced.

       translator_args     translator_args  is  a  list  of  valid ctrans command line arguments to be passed to
                           ctrans.  Metafile frames are translated by ctrans and the output of this  translation
                           is  made  available  for  further  processing  as  specified by the remaining spooler
                           definition.

       filter_chain        is a set of simple commands separated by the UNIX pipe symbol |.  filter_chain may be
                           terminated by the UNIX file redirection symbols > or >> filename.  Output from ctrans
                           is made available to the processes defined in filter_chain.

       A pound-sign (#) as the first character indicates a comment line which is ignored by routines  that  read
       this  file.   The order of entries in ncarv_spool is important. If an alias name conflict arises the last
       definition encountered is given precedence. Any previous definition for the same alias name is discarded.

EXAMPLES

       The following is an example ncarv_spool file. The first entry describes a device named postscript.   When
       postscript  is  named  as  the  spooling device, metafile frames are translated by ctrans into the format
       described by the ps.mono graphcap. The font font1 is used for CGM text  elements.   The  result  of  this
       translation  will  be piped to lpr.  The second entry is named dicomed.  The dicomed entry specifies that
       metafile frames will be rasterized at a 1857 by 1183 pixel resolution and output in X11 xwd  format.  The
       result  of this rasterization is piped to a program x11tonrif which in turn sends its output to a program
       called rasttg.  In the third example the final output is directed to a file called sunfile.

ENVIRONMENT

       NCARG_ROOT
              Path to root of NCAR Graphics installation.

       NCARG_LIB
              If set this variable contains the path  to  the  installed  NCAR  Graphics  libraries.   NCARG_LIB
              overrides NCARG_ROOT.
