Re: Empty PS/EPS

Hi Walter,

I wondered about this issue when it first appeared and then inexplicably disappeared -- must be sun spots, or something :-/
When you say "empty" PS files, do you mean zero-lengthed files, or empty of graphics (that is, is there at least some postscript preamble written to the files but no actual graphics, or are they just plain empty)? Is it dataset dependent; i.e., if it works for one dataset, it always works? And when it fails, do you always get the GKS error cited below?

I'm not sure what to advise at this point -- If there's anyway to get ahold of a test case that exhibits the problem, that would be hugely useful.

Then it'll work again the next day once or twice before breaking again. PDF works reliably. I believe the problem is related to the following one I posted on the ncl-install list (http://www.ncl.ucar.edu/Support/install_archives/2012/0210.html), which may help isolating the bug. When I set cnFillMode = "RasterFill", I get the following warnings:
