I have this script that someone helped write but I need to change the PNG bit depth to 16-bit and my attempts failed. Is there a glossary for these terms?

import sys
r = nuke.nodes.Read(file = sys.argv[1])

g = nuke.nodes.Vectorfield()
g.setInput( 0, r )
g['vfield_file'].setValue('cubeListHere')

w = nuke.nodes.Write(file = 'cubeListHere.png')
w.setInput(0, g)
nuke.execute("Write1", 1,1)

Not sure if you can do it in one line, but this should work:

w = nuke.nodes.Write(file = 'cubeListHere.png', file_type = 'png')
w['datatype'].setValue('16')

I generally query help: help(w) for whatever node I'm dealing with in Nuke, but you can get the documentation for all of the classes and methods in the Nuke Python Reference (http://docs.thefoundry.co.uk/nuke/63/pythonreference/), but if you're just starting out, the Python developer guide (http://docs.thefoundry.co.uk/products/nuke/developers/63/pythondevguide/) is pretty handy and easy to read.
