[vtkusers] Profile an image?

[Amy Henderson]

Use vtkLineSource to create a line with the 2 selected end points.  (The 
Resolution variable will determine at how many evenly-spaced points along 
the line you will sample the image.)  Then use vtkProbeFilter with your 
image data as the Input and the output of vtkLineSource as the Source.
