psmegaplot - To create poster-size PostScript plots from page-size plot
psmegaplot plotfile -Sscale [ -C ]
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.
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]
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 -S 3 -C > hawaii_contour_megaplot.ps
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.
