Re: ferret -gif limitations?

Hi Bruce,
Can you use "ferret -batch" or MODE metafile  and make postscript
plots?  I'm not aware of any particular problems with .gif, but the
resolution of the plots isn't as good as with postscript.   If you search
the email archives for the words "resolution" and "gif"  you'll see some
messages about the issue.

And, here's an old message about the bug with frame/format=gif.  It doesn't
have to do with Redhat 7.2
