[Insight-developers] SpatialFunctionImageEvaluatorFilter

[Damion Shelton]

Hi,

That's correct. I wrote this filter prior to the flood fill stuff 
existing as a clumsy way of dumping the output of a spatial function 
into an image. The actual functionality of this class should probably 
(as you suggest) be rolled into a new class called 
SpatialFunctionImageSource. There is a class that is sort of like this 
called GaussianImageSource, which is specialized for the Gaussian 
spatial function object, but it would be pretty easy to do a more 
generalized version.

To me, it's a good idea to always carry two sacks of something when you 
walk around. That way, if anybody says, "Hey, can you give me a hand?" 
You can say, "Sorry, got these sacks."
