Thank you Seb,
For your first question : Yes, I succeeded in using my SimpleImageThreshold in
Python Shell.
Here is my script in Python Shell:
reader = OpenDataFile('/path/to/my/file.mhd');
GetDisplayProperties();
ColorAttributeType ='POINT_DATA';
SetDisplayProperties(Representation='Volume',ColorArrayName='MetaImage');
Render();
reader2=SimpleImageThreshold(reader);
SetDisplayProperties(Representation='Volume',ColorArrayName='ImageScalars');
Render();
For the second part :
I have the following errors when I tried in different ways:
var reader = paraview.OpenDataFile('path/to/my/file.mhd');
ST = paraview.plugins.SimpleImageThreshold;
ST.SimpleImageThreshold(proxy) :
error : proxy not defined
ST.SimpleImageThreshold(reader)
error:Traceback (most recent call last): File "<jsonrpc>", line 146, in
handle_request
TypeError: SimpleImageThreshold() takes exactly 1 argument (3 given)
ST.SimpleImageThreshold({proxy:reader});
Error: Traceback (most recent call last): File "<jsonrpc>", line 144, in
handle_request File "/home/thtran/PV/workdir/plugins/SimpleImageThreshold.py",
line 11, in SimpleImageThreshold
servermanager.ActiveConnection.Modules.filters.SimpleImageThreshold(proxy)
AttributeError: 'PVModule' object has no attribute 'SimpleImageThreshold'when I
use :
var reader2 = ST.SimpleImageThreshold(proxy);
var reader2 = ST.SimpleImageThreshold(reader);
var reader2 = ST.SimpleImageThreshold({proxy:reader});
Same errors as above.
I think that I have to be more precise in SimpleImageThreshold.py but I don't
have any clue.
Thank you very much Seb
I followed your advice. Here is my SimpleImageThreshold.py to be sure :
from paraview.simple import *
import os
import threading
def SimpleImageThreshold(proxy):
servermanager.ActiveConnection.Modules.filters.SimpleImageThreshold(proxy)
def createSimpleThresholdView():
global dp
dp = GetDisplayProperties()
dp.LookupTable = MakeBlueToRedLT(37.35,276)
dp.ColorAttributeType = 'POINT_DATA'

Hi Alex,
First of all, you should be able to remove those lines, they are not
needed in your case.

> # server
Then my question will be: Did you managed inside the Python shell of
ParaView to call manually the load plugin and to instantiate your
filter the way you are doing it in ParaViewWeb ?

to solve that issue you need to change your python plugin so the
method will look like that:
def SimpleImageThreshold(proxy):
....SimpleImageThreshold(proxy)
and in JavaScript that will be
ST.SimpleImageThreshold(proxy);
note that I've removed the {}.
