vtkImageShrink3D can do antialiasing, and can't be used to magnify
images.
vtkImageResample can be used to either magnify or shrink images,
but cannot do antialiasing.

Also, there is vtkImageReslice, which can be used to do the same
sorts of things as vtkImageResample but which can provide additional
operations such as cubic interpolation or image rotation.
