[vtkusers] interpolating vtktexture

[Andrew Wheatley]

Hello:

I have a vtkTexture.  The input, of course, is a vtkImageData.
In my case, the vtkImageData is 2D.
A vtkTexture object has an option to SetInterpolation, which
does a linear interpolation on the texture data.  My question
is:  How can I get the interpolated data in the form of
a vtkImageData?

Regards,
