Hi Hari,

In VTK 4.x there is a vtkPolyDataToImageStencil filter that can
be used to mask an image using vtkPolyData.  An example is located
in VTK/Hybrid/Testing/Tcl/TestImageStencilWithPolydata.tcl.  You
would have to replace the image reader with something that will
produce a blank initial image, e.g. a vtkImageGridSource where
the LineValue and FillValue are both set to zero and where the
DataExtent, DataSpacing and DataOrigin are correctly set.

The vtkPolyDataToImageStencil is not perfect, sometimes it 'leaks'.
