Re: GIF ouput

[Julien Demaria <dem@xxxxxxxxxx>]

Hi,

I've still the GIF ouput problem : in use this command : ferret -nojnl -gif 
-server < myscript.jnl
which make only this :

plot/line/vs {2,3},{5,6}
frame/file=p.gif
q

On my Windows 2000 system (and Ferret 5.51) it seems work some times and 
doesn't work other times...
On my Windows NT system (and Ferret 5.51 or 5.53) it never works : I have 
sometimes a corrupted (bad LZW ...) GIF, or a GIF all white with some black 
lines on the top, randomly changing...

Are there solutions to my problem ?

Thanks in advance for help,

Julien
