GrADS Utilities: gxtran

## gxtran

`gxtran [ -airg <infile> ]`

This utility is used to display GrADS meta files containing single frames or animations (multi frames).

The options are:

`-i fname` identifies input GrADS metacode file
`-a` animates the frames without user hitting return in the command window
`-r` reverses background/foreground colors
`-g geom` sets the geometry of the X window as in any other X application.
`` `geom` has the form WWWxHHH+X+Y, giving a display window
`` WWW pixels wide and HHH pixels tall starting at point X,Y on the screen.

Usage Notes

Without any options, `gxtran` prompts the user for the name of the GrADS meta file. To quit gxtran, hit return in the command window.

Examples

`gxtran -a -g 800x600+0 -i mytest.mf`

This command would open a window of size 800x600 starting at the upper left corner of the screen and animate all frames (plots) in the file `mytest.mf`.
