Hi Bill,

This all looks quite exciting.

You can call store.setPlanePositionX (and Y+Z) to set the absolute
physical position (which can be negative--it's stored in floating
point). However, this is a per-plane parameter based upon a global
origin; with the current model you can't specify a global origin and
then use relative values, which would be nice, as far as I can see.

See http://www.openmicroscopy.org/Schemas/OME/2013-06/ome.xsd
(Plane -> PositionX/Y/Z).  Note that the units are unspecified; adding
units here and in other parts of the model is something we're currently
looking into.


Regards,
Roger
