Hi Mark,

I am not sure I understand exactly. I know what you mean generally, I understand how to include support modules in other applications or support modules, but I don't know how to do it with areaDetector. Where are the other NDPlugins defined? Can I just copy the source code and database from Michael's NDWarp into some location in areaDetector core and rebuild?

Thanks

Will

You need to recompile your areaDetector application to include this new plugin.  You need to add it to the application dbd file and include the library in your application Makefile.

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.
