[vtkusers] Faster way to create a vtkImageData with a single value

[hchen]

it may be faster if you fill the image matrix in Python and then use
vtkImageImportFromArray to get it into vtk. it would something like:

from vtk.util import vtkImageImportFromArray as viifa
a = np.ones( (3, 4, 5), dtype=np.uint8 ) * BackgroundValue
...
f = viifa.vtkImageImportFromArray()
f.SetArray( a )
f.SetDataOrigin( ... )
f.SetDataSpacing( ... )
f.SetDataExtent( ... )
f.Update()
vimg = f.GetOutput()

--good luck.
