[vtkusers] smoothing vtkImageData with vtkImageGaussianSmooth

[Liam Kurmos]

Hi All,

I want to smooth some 3D image data with vtkImageGaussianSmooth, but i
can't seem to connect the pipeline. The filter wants a
vtkAlgorithmOutput* as input but i don't know how to get one for a
vtkImageData.

the example in the wiki uses vtkImageCanvasSource2D->GetOutputPort()
which isnt what i want.
How should i connect these two? also if there is a way i could have
found this out (other than asking) i'd be very grateful if you can let
me know.

cheers,

Liam
