NAME

     psmegaplot - To create  poster-size  PostScript  plots  from
     page-size plot

SYNOPSIS

     psmegaplot plotfile -Sscale [ -C ]

DESCRIPTION

     psmegaplot reads a PostScript file and 'blows it up'  by  an
     arbitrary  scale.  The  result is several plots that make up
     the pieces in a jigsaw puzzle. Cut and paste these pieces to
     make  a  'megaplot'.   NB!  Any rotation/translation/scaling
     performed at the top of the original PostScript file must be
     reversed  at  the end of the file in order for psmegaplot to
     work. Also, there must be no showpage command at the end  of
     the file. (Run GMT programs with the -K option)


     plotfile
          PostScript file as created by the GMT  programs  or  by
          other means.

     -S    Multiply the x- and y-dimension by scale.  scale  must
          be larger than 1.0.

OPTIONS

     No space between the option flag and  the  associated  argu-
     ments.

     -C    Plot crop marks in each corner of every  output  page.
          [Default is no marks]

EXAMPLES

     To magnify a contour-map PostScript file 3 times,  giving  a
     total of 9 output pages to be pasted together, try

     psmegaplot    hawaii_contour.ps     -    S3     -    C     >
     hawaii_contour_megaplot.ps
