[vtkusers] How to disable a VTK filter that is connected to a VTK pipeline

[Allan James]

Hi all,

Does anyone know if it is possible to disable a VTK filter without removing it from the pipeline?

For example, while using vtkImageMask, I would like to allow the user to be able to select whether to apply a mask to an image or not - I would like to enable/disable the vtkImageMask filter during runtime without having to disconnect/reconnect the pipeline everytime.

I am sure there are work-arounds depending on the filter in question (such as setting a null mask image perhaps?) - however, generally speaking it would be nice to be able to disable a filter and have the input data pass through untouched - is this possible in VTK?

Thanks,
