## gxeps

`gxeps [ -acdklrsv -i <infile> -o <outfile> ] [<infile>]`

Converts the GrADS metacode format file to a PostScript file. Where:

`-i fname` identifies input GrADS metacode file
`-o fname` identifies output postscript file
`-b` prints black and white plot
`-c` prints color plot (default)
`-r` prints on a black background
`-d` appends CTRL-D to the file, useful if printing on a HP1200C/PS color printer

`-L` Ask for a label to be printed on the plot
`-n` Ask for a note to include in PostScript file header
`-s` Add a file and time stamp on the plot.

Usage Notes

1. The default behaviour of `gxeps`is to create a grayscale plot on a white background. The GrADS default rainbow colors (color numbers 2 to 14) are converted into appropriate grey shades. User-defined colors (numbers above 15) are translated to greyscale intensity based on their green content only.
2. For more information, see the section in the User's Guide on Producing Image Output from GrADS.

Examples

1. `gxeps -a`

2. `gxeps -rc -i mytest.mf -o mytest.ps`
   Converts GrADS metacode format file `mytest.mf` to a color plot on black background and outputs the result to PostScript file `mytest.ps`.
