[vtkusers] Profile an image?

[dean.inglis at camris.ca]

Hi Beau,

An example of an image profile is here: 

Examples/GUI/Tcl/ProbeWithSplineWidget.tcl

You could write a simple function/callback to quantize 
the spline's output vtkPolyData points
to match image voxel/cell centers or points...
an implementation of this is done in
vtkImageTracerWidget's Snap() member function.
