[ncl-talk] saving high resolution plots for publications

[Barry Lynn]

Guido:

Thank you for the tip.

How do set the NCL script to output in EPS format?

When I use PDF, I find that the resolution isn't always high enough
(especially when I have very small map panels).

When I blow up the screen, I lose resolution.  This doesn't happen with png.
