[vtkusers] vtkImageColorViewer

[David Gobbi]

Hi José,

Before calling "del" you should remove it from the pipeline.  This is
done with any one of these three calls:

object.RemoveAllInputs(), if the object is a vtkAlgorithm

object.SetInputConnection(None), if the object is faking a vtkAlgorithm

object.SetInput(None), if the object still uses the old pipeline API

After that, the "del" should release the memory immediately.  If it
doesn't, you can always force the garbage collection:

# force python garbage collection
import gc
gc.collect()

# force VTK garbage collection
import vtk
vtk.vtkGarbageCollector.Collect()

Forcing the garbage collector usually isn't necessary if you have
disconnected the object from the pipeline.

Cheers,

    David
