[Insight-developers] SpatialFunctionImageEvaluatorFilter

[Lydia Ng]

Hi,

I have a question about the SpatialFunctionImageEvaluatorFilter which
evaluates a SpatialFunction over an output image domain. It is subclass
from ImageToImageFilter but as far I can tell it does not make use of
the input image in generating the data for the output.

Wouldn't it make more sense for it to derive from ImageSource? It seems
like the only purpose for the input image is to set the meta-information
(Origin,Spacing,LargestPossibleRegion) of the output.
