Re: [Paraview] Write and read a vtk file (in python)
Hello,
Thank you Eric : now I can read my datas with a ProgrammableSource, and
display them.
But I would like to create a ProgrammableSource in a python script, and
I have this error when I try to set the InformationScript (which is
necessary to display the datas) attribute :
Traceback (most recent call last):
File "string", line 1, in module
File "/home/plumecoq/EHPOC/plugins/ElsaMenu/elsa.py", line 106, in

File
"/home/plumecoq/Paraview/ParaView-3.8.0-bin/Utilities/VTKPythonWrapping/paraview/servermanager.py",
line 201, in __setattr__
"to add this attribute.")
AttributeError: Attribute InformationScript does not exist. This class
does not allow addition of new attributes to avoid mistakes due to
typos. Use add_attribute() if you really want to add this attribute.
My code is :
# solution 2 : Programmable Source
ps = ProgrammableSource()
ps.OutputDataSetType = 2 # 2 : Structured Grid, 13 :
MultiblockDataSet
str_script = """
import lecture_v3d as v3d
reader =
v3d.V3dReader("/home/plumecoq/tmp/ParaView/flow_1_0075.v3d")
self.GetOutput().DeepCopy(reader.bloc_vts)
"""
ps.Script = str_script
str_information_script = """
from paraview import util
util.SetOutputWholeExtent(self, [0, 10, 0, 10, 0, 30])
"""
ps.InformationScript = str_information_script
when I put the string str_information_script in the window
Script(RequestInformation) of the ProgrammableSource, it works fine.
any ideas ?

Hey Jrme,
Yes, you can use the Python Programmable Source as a reader.
There are some examples on these two pages, in case you haven't seen
them:

thank you very much !
Do you know if is possible to write directly a reader in python ?
Or is it only possible in C++ ?

1) reading :
from a vtkStructuredGrid object, I use a vtkStructuredGridWriter to create a
vtk file, and I have the following problem :
when I launch the script in Paraview, the format of floating points is not
good (I obtain for example 33,1632 instead of 33.1632). So, the file created
is not readable by Paraview. If I launch the script directly in a terminal,
it works fine. Perhaps because the version of vtk module is not the same ?
If I use the binary format I have not this problem.
This seems to be related to the way the LOCALE is set on your system. It is
probably set to French in one case and English in the other. Does anybody know
if we can force LOCALE to English in the ParaView application or the reader?
