Eleven Sandstones Plotting Example
=========================

This example shows how we can load an image from the eleven sandstones dataset.

.. GENERATED FROM PYTHON SOURCE LINES 8-11

.. code-block:: default

    from drd.datasets.eleven_sandstones import load_eleven_sandstones
    import matplotlib.pyplot as plt

Loading the Image
------------------------
We will use one of the utility functions called `load_eleven_sandstones` to generate an xarray DataArray 
which already contains all the spatial axis information and scaling preconfigured.

This way we will have a proper definition of the image data in terms of a spatial coordinate system.

.. GENERATED FROM PYTHON SOURCE LINES 18-23

.. code-block:: default

    img = load_eleven_sandstones("Berea", "Berea_2d25um_grayscale.raw")

    # This is the end of the 'code block' (if using an above IDE). All code within
    # this block can be easily executed all at once.
