[vtkusers] Interpolation ???

[Weinheimer, Oliver]

Hi,

2 suggestions:

1)
read the images in as a 3d dataset (vtkImageData)
and then you can use vtkImageResample with SetAxisMagnificationFactor(2, 2).
You can choose the
interpolation mode by resample->SetInterpolationMode()

2) 
write it by your own:
generate  a new empty 512x512 matrix and do an linear interpolation pixel by
pixel (or any other kind of interpolation)
	
regards
Oliver
