[vtkusers] How to save the stenciled images?

[Cory Quammen]

Try vtkXMLImageDataWriter:
http://www.vtk.org/doc/nightly/html/classvtkXMLImageDataWriter.html.
It will save a single 3D image to a file with the data type of your CT
image (probably unsigned shorts), so you don't have to worry about the
lower dynamic range of BMP or JPEG images. To read it back, use the
vtkXMLImageDataWriter class.

Hope that helps,
Cory
