Hi Michael,

This looks perfect. How do I include a new ND plugin in an existing area Detector installation?

It may well be stale at this point, but my NDWarp plugin can do this.

https://github.com/mdavidsaver/ndwarp/blob/2eb73105dd886c9dc89e96b3d77661b9bf770a02/warpApp/Db/NDWarp.template#L40

Rotation being one case of the possible coordinate transformations.
The name "warp" coming from skimage, which I used for prototyping.
