PSMEGAPLOT(1gmt)					       Generic Mapping Tools						  PSMEGAPLOT(1gmt)

NAME

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

SYNOPSIS

       psmegaplot plotfile -Sscale [ -C ]

DESCRIPTION

       psmegaplot  reads  a  GMT-produced  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'.

       plotfile
	      PostScript file as created by the GMT programs.

       -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 arguments.

       -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, use

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

BUGS

       This program is unlikely to work on non-GMT-produced PostScript files since it anticipates the structure of the file.  It also assumes that
       the output media is Letter size.
