Allow loading of the reference viewer from a script

I have some data which is not in FITS files but I would like to load into the reference viewer, it’s multidim data, I have a dict and a 4D array. I would really like to be able to do something like:

from ginga.main import ReferenceViewer

r = ReferenceViewer()
r.main(data, header)

Looking at the code for the reference viewer this looks like it might be a little bit of a fiddle, do you have any suggestions?

(FWIW, the data is loaded independently of the header from a raw binary file, so a reader would be a major pain as well)

The notebook I listed shows how to connect to the reference viewer running the usual plugins. I just used a notebook to put together the “client” example.

@Cadair, python 3 issue I referred to above is fixed. Assuming you started the RC plugin (from the plugins menu or when starting ginga just add --modules=RC) you can do what you are asking with:

from ginga.util import grc
viewer = grc.RemoteClient('localhost', 9000)
ch = viewer.channel("Image")
ch.load_np("image1", data, 'fits', header)

There is more info in the manual page for the RC plugin
