[Paraview] ParaViewWeb, vtk filters python description

[Alex]

Thank you Seb,
   You mean the ParaView plugin at startup? Indeed, I copied the dynamique library .so in /install/lib/paraview-3.14/plugins and the plugin is loaded automatically into ParaView. It is then usable immediately in Python Shell.
   However, I doubt that I can use the plugin directly in ParaViewWeb without loading it.
   For exemple, I have a MyImageThresholdSMPlugin.so, also the plugin's name is MyImageThreshold. I called it sucessfully in Python Shell directly with reader2=MyImageThreshold(reader,ThresholdRange=[300,600]); (the values are given for exemple).
   In ParaViewWeb, can I use it directly by calling var reader2=paraview.MyImageThreshold({Input:reader, ThresholdRange:[300,600]}); ?
   In your previous reply, I have to load a Plugin by LoadPlugin command from simple.py. And then define a function that call the servermanager.Activeconnection.Modules.filters.MyImageThreshold(proxy) I wonder if they are the same thing? That why I ask if we have to write a MyImageThreshold.py so that our plugin is usable in ParaViewWeb.
   

   Alex

If you managed to load your plugin (the C++ ParaView one) at startup,
then you will be able to use your filter as any other filter in
ParaViewWeb without using any ParaViewWeb plugin. Otherwise, the
python file that you are missing is in fact an XML file that list the
properties for each filters and sources inside ParaView.

PARAVIEW_src/ParaViewCore/ServerImplementation/resources/filter.xml

The labels without space are used as filter name and properties for
creating and controlling those filters...

Otherwise inside your ParaViewWeb plugin, you can provide a dictionary
as argument and just loop through its entry and set them in python.
