[Paraview] tikz/tex export for paraview contour plots

This is slightly off-topic, but I have been using a similar approach
(tikz/tex + png images) to include plots from python/matplotlib in my
LaTeX documents. For this I can just recommend the matplotlib2tikz
package [1].

Using VTK/ParaView, I have had some attempts to set the render window
size and camera in python scripts, but could not yet figure out how
to extract the information on the data/viewport extend.

My VTK and ParaView scripts are based on information I gathered from two
mailing list discussions, see [2,3]. My scripts are probably not much of
help, but I can dig them out if you are interested.

That's the missing piece in the puzzle I couldn't quite figure out yet,
but I would also be interested in this. The code in discussion [2] has
some examples on coordinate transforms in VTK, but I didn't have the
time to look deeper into this.


Cheers,
Armin
