[Insight-developers] compose affine with header filter?

[Cory Quammen]

Hi Michael,

I don't know of a filter that does what you describe, but it sounds
like you want this filter to essentially produce an image on a
potentially sheared grid. Does this correctly characterize what you
want the filter to produce?

An image defined on a sheared grid fits in with a recent discussion on
this list about supporting images whose samples do not lie at regular
intervals along orthogonal directions, so I'm interested in knowing
more about what you are trying to do with this filter.

Thanks,
Cory
