Subject: ImageJ AD Plugins and PVXS

Hi all,

We're doing some work using PVXS and debugging using the ImageJ AD plugins, and I'm finding something that just doesn't make sense to me. Here's the run down:

For each pvxs::Value, we have two dimensions, as these are array values. Based on the specification in the documentation (https://docs.epics-controls.org/en/latest/pv-access/Normative-Types-Specification.html) I see:

" A dim] of 2 elements describes a matrix, where the first element of dim gives the number of rows, and the second element of dim gives the number columns."

When I set my array up and then send the image to the ImageJ NTNDA_Viewer plugin, I find that dims[0] is the x-axis, while dims[1] is the y-axis, which is the opposite of what I'd expect given the normative type specification.

Just curious if anyone else has run into this, or if I'm missing something obvious.
