Hi Alex,<br><br>First of all, you should be able to remove those lines, they are not<br>needed in your case.<br><br>> import os<br>> import threading<br>><br>> LoadPlugin('.../vtkSimpleImageThreshold/bin/libSimpleImageThresholdSMPlugin.so',True)<br>> # server<br><br>Then my question will be: Did you managed inside the Python shell of<br>ParaView to call manually the load plugin and to instantiate your<br>filter the way you are doing it in ParaViewWeb ?<br><br>> And, one more question. How can we define SimpleImageThreshold() in .py file<br>> so that they can act like a real filter? Take in an image, do<br>> his work, and we have an image thresholded as ouput?<br>><br>> Reason : when I called reader2 = ST.SimpleImageThreshold({proxy}); log file<br>> :<br>><br>> Traceback (most recent call last):<br>> File "<jsonrpc>", line 144, in handle_request<br>> TypeError: SimpleImageThreshold()
