[yt-users] Images of extracted regions

[Britton Smith]

The first is definitely possible.  Just add data_source=extractCube to your
call to add_projection or add_slice or whatever.  The second probably won't
work because the projection or slice routine will look for other things like
cell dxs that won't be present from just a similarly sized array.  If you
want to do something like that, you're probably better off making a new
field and then projecting that with the above data_source keyword argument
in there.
