# psmegaplot(1gmt)

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

## NAME

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

## SYNOPSIS

**psmegaplot** *plotfile* **-S***scale* \[ **-C** \]

## 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 **-S** 3 **-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.
