[ferret_users] simultaneous GIF and postscript

[John Donners <j.donners@xxxxxxxxxxxxx>]

Hi all,

I generate plots with ferret that are then served to a website.
Usually I make GIF plots (with ferret -gif), because of their size.  
Sometimes
I also make postscript plots (with ferret -batch), e.g. for  
publication purposes.
I would like to generate both a postscript and a GIF at the same time  
in one ferret
session, without having to repeat the calculation. However, ferret  
only allows to
generate either GIF or postscript at a time. When I use 'ferret - 
unmapped', I get
a good postscript, but a completely black GIF file. It is possible to  
do this interactively
with  visible X11 windows (the normal way), however not on a webserver.
Ideas are welcome.

Cheers,
John
