Get current viewer#
Get a reference to the current napari viewer.
Whilst this example is contrived, it can be useful to get a reference to the viewer when the viewer is out of scope.
import napari
# create viewer
viewer = napari.Viewer()
# lose reference to viewer
viewer = 'oops no viewer here'
# get that reference again
viewer = napari.current_viewer()
