[vtkusers] Converting vtkImageStencil to vtkImageData

[David Gobbi]

Hi Hendrix,
 
 There is a way to do the conversion indirectly: first you need to
 create a blank image of the correct size, and then use the
 vtkImageStencil filter to convert the blank image into a mask
 by passing it through the stencil.
 
 To create a blank image, you could (for example) use a 
 vtkImageEllipsoidSource() and use the same InValue and
 OutValue.
 
 This is a little bit more complicated than it should be!  It
 would be nice if there was a vtkImageStencilDataToImageData
 filter that could do all the work in one step.
 
 Tell me how it goes.

Subject: [vtkusers] Converting vtkImageStencil to vtkImageData

Hi fellow VTK users,

I'm wondering if there's a way to convert a vtkImageStencil into a 
vtkImageData for further processing (like morpholocigal operations or saving 
as a binary image mask).

Regards
 Hendrik
