Dear Utkarsh,
Just yesterday I stumbled over vtkImplicitTextureCoords. Could that be used to
achieve my initial idea, ie to avoid the paraview clipper for clipping images
"roughly"? I managed to create an xml-file that loads as a filter-plugin in
paraview but after execution, there seems to be no texture available to use for
rendering. I'm not sure if using ProxyProperty, ProxyGroupDomain and
ProxyListDomain is doing the same for a filter instead of a source as in Your
original XML. Are those tags the same as InputProperty, DataTypeDomain otherwise
used for the input of a filter-plugin?
If that is correct, what else could I be missing?
Many thanks for looking into this.

Many thanks for Your reply, Your effort to create an XML-plugin and the bug
report. Would it help to compile paraview from source with
Module_vtkImagingStencil set to ON on our own platform for testing or is
there some code adjustment of paraview necessary to allow that?
No, it won't help. I did exactly that an ran into issues with
vtkImageStencil and ParaView. Evidently, we hadn't tried to use that
data-object in ParaView before.
I guess it would not help to specify the location of a separately compiled
vtk-5.10?
You are correct, it will not help. We need to track the issue down on
the ParaView side first.
Do I understand correctly that with using port_index= You specify which
output should go to which input?
That is correct. If not specified, 0 is assumed.
What is calling e.g. the vtkImplicitPlaneWidget to get the interaction
widget for specifying the implicit function parameters?
In this case, it's the "ProxyListDomain" associated with the
"ImplicitFunction" property. The domain refers to proxies viz.
("implicit_functions", "Plane"), etc. If you look at the xml
definitions for the same in ParaView
(ParaViewCore/ServerManager/SMApplication/Resources/utilities.xml),
you'll see that it provides a "<Hints>" section that suggests a
"PropertyGroup" of type "Plane". That's what's causing the GUI to show
the vtkImplicitPlaneWidget to control the Origin and Normal
properties.
Hope that clarifies things a bit.
