img (trollimage.xrimage.XRImage): Image object to save to disk.
filename (str): Optionally specify the filename to save this
dataset to. It may include string formatting
patterns that will be filled in by dataset
compute (bool): If `True` (default), compute and save the dataset.
If `False` return either a `dask.delayed.Delayed`
object or tuple of (source, target). See the
return values below for more information.
**kwargs: Keyword arguments to pass to the images `save` method.
Value returned depends on `compute`. If `compute` is `True` then
the return value is the result of computing a
`dask.delayed.Delayed` object or running `dask.array.store`. If
`compute` is `False` then the returned value is either a
`dask.delayed.Delayed` object that can be computed using
`delayed.compute()` or a tuple of (source, target) that should be
passed to `dask.array.store`. If target is provided the the caller
is responsible for calling `target.close()` if the target has
