Re: [Paraview] ParaView v5.2.0: Problems with inspecting Use Below (Above) Range Color

[Nenad Vujicic]

Utkarsh,

Thank you very much! I made mistake by casting vtkScalarsToColors to
vtkLookupTable always, without inspecting of other branches! When I put
conditional checking if it is maybe
vtkPVDiscretizableColorTransferFunction, it started working! Thank you very
much for your help!

Nenad.

Where are you getting the vtkLookupTable from? ParaView doesn't use
vtkLookupTable directly, is uses vtkPVDiscretizableColorTransferFunction

[Paraview] ParaView v5.2.0: Problems with inspecting Use Below (Above) Range Color

[Nenad Vujicic]

Hello everyone,

I'm trying to inspect values of "UseBelowRangeColor" and
"UseAboveRangeColor" flags from my ParaView exporter plugin by:

1. Retrieving vtkCompositePolyDataMapper2 from currently active view and
rendering window, then,
2. Getting it's vtkLookupTable and then calling GetUseAboveRangeColor() and
GetUseBelowRangeColor(),

However, first call (for checking using above range color) always passes
and returns some big number and second one (for checking using below range
color) always crashes, regardless whether flags are turned ON / OFF in
ParaView UI.

Any suggestions about this or ideas how I could pick up these values in
different way?

Thanks in advance!
Nenad.
