Re: octaviz without render window

I don't think image output is possible without a render window.  There 
is also an issue with the render window needing to be on top; if it is 
behind another window, the image output will show the overlapping 
window.  However, there is a workaround by using Xvfb (X virtual frame 
buffer).  You can do something like:

$ Xvfb :1 -screen 0 800x600x16 &
$ export DISPLAY=":1.0"
$ octave
(plotting commands; all X output will be directed to the virtual screen)
$ exit
$ killall Xvfb

HTH,
Jonathan

Dear all,

I am a long time user of (basic) functions of octave.
I am running GNU Octave, version 2.1.73 (powerpc-unknown-linux-gnu).

Now I have run into a small problem.

I have been using gnuplot and its low and high level plot commands in
octave to generate png and eps files through a web interface.

Up to here no problem. but ...

I am looking at switching to octaviz for my 3d plotting needs but I
am not able to figure out how I can generate a file (png and/or eps)
without having a render window showing up.

Can anybody point me in the right direction?

Kind regards,

Lieven
