[gradsusr] How do I get a map to fill the entire output PNG?

[James T. Potemra]

Hi Rupak,

I think the extra steps you list are only needed if you draw the map.  
In Christopher's case with "mproj off" and "mpdraw off" (ditto 
labels/grids, etc.), all you need to do is specify the parea.  So, if 
you start grads in landscape, "set parea 0.0 11.0 0.0 8.5" added to 
Christopher's script will make a image without a border.
