Hello Peter,
I was king of hoping you would reply, I actually saw that post and your
method of instantiating an object on vtkGL2PSExporter does work after I
do a from paraview.vtk import *
from paraview.vtk import *
exp = vtkInstantiator.CreateInstance("vtkGL2PSExporter")
I have tried exp.Write() but I get an error indicating:
vtkGL2PSExporter: No render windows provided
Then I did a couple of stabs in the dark with vtk.vtkRenderWindow() to
try an get a Render Window object but with no success, I get attribute
errors that I think are coming from me mixing up namespaces. I am doing
the import line above and from vtk import *, I wonder if that is messing
me up. I am going to read up on Python to get to the bottom of this, but
a quick hint is also appreciated.
Thanks,
Marcin

Hello Marcin,
Your question may have already been answered here:
http://markmail.org/message/zd2nwsztxl4xwbhm.
However I think the last time I tried this was in 3.4 so things may
have changed. In my experience the vtkPostScript writer does a better
job although it has been quite a while since I've tried gl2ps.
Good luck,
Peter.

Hello,
I am trying to figure out how to save a visualization in Paraview
directly to ps/eps format.
I have compiled from source paraview 3.6 with the configuration
option VTK_USE_GL2PS set to ON.
There are many hits in the mailing list archives regarding trying
to use vtkGL2PSExporter to achieve this but I couldn't find
anything that I could make work.
I know that I can just use WriteImage("test.eps",
Writer="vtkPostScriptWriter") in the python shell to get what I am
asking for.
However, I wonder if GL2PS could provide a better looking eps
file, and having spent a couple of hours on this, I would really
like to get to the bottom of this.
I have looked at the vtkGL2PSExporter class reference at
http://www.vtk.org/doc/nightly/html/classvtkGL2PSExporter.html and
from there followed the vtkGL2PSExporter (Tests) link which
provides examples of unit testing that is done on the class. One
example is actually titled "test vector EPS output"
However, even after doing a: from paraview import vtk in the
python shell, when I try to follow the test example and do exp =
vtk.vtkGL2PSExporter() I get the following error:
AttributeError: 'module' object has no attribute 'vtkGL2PSExporter'
Can anyone shine any light on how to actually utilize the
vtkGL2PSExporter in Paraview to export an .eps, my impression is
that it has to be done in the Python Shell, and I am not very
familiar with Python.
Thank You,
Marcin Sliwowski
