Resize
======

The :meth:`resize` method adjusts the spatial dimensions of a `DataCube` to a new width and height by interpolating each spectral layer.  It preserves the original spectral resolution (the wavelength axis) while changing the pixel grid to the user-specified size.

.. note::
   Apart from :meth:`resize`, the :class:`DataCube` class provides many other operations.  See :ref:`DataCube Operations <DataCube_Ops>` for details.

Example
-------

Below is an example that loads a sample data cube, resizes it to half its original width and height, and then displays one of the wavelength slices.
