.. currentmodule:: scipy.misc

Various utilities that don't have another home.

Note that Pillow (https://python-pillow.org/) is not a dependency
of SciPy, but the image manipulation functions indicated in the list
below are not available without it.

.. autosummary::
   :toctree: generated/

   ascent - Get example image for processing
   central_diff_weights - Weights for an n-point central m-th derivative
   derivative - Find the n-th derivative of a function at a point
   face - Get example image for processing
   electrocardiogram - Load an example of a one-dimensional signal.

Deprecated functions:

.. autosummary::
   :toctree: generated/

   bytescale - Byte scales an array (image) [requires Pillow]
   fromimage - Return a copy of a PIL image as a numpy array [requires Pillow]
   imfilter - Simple filtering of an image [requires Pillow]
   imread - Read an image file from a filename [requires Pillow]
   imresize - Resize an image [requires Pillow]
   imrotate - Rotate an image counter-clockwise [requires Pillow]
   imsave - Save an array to an image file [requires Pillow]
   imshow - Simple showing of an image through an external viewer [requires Pillow]
   toimage - Takes a numpy array and returns a PIL image [requires Pillow]


Deprecated aliases:

   factorial2 - Double factorial, ``(n!)!`` (imported from `scipy.special`)
   factorialk - ``(...((n!)!)!...)!`` where there are k '!' (imported from `scipy.special`)
   logsumexp - Compute the log of the sum of exponentials of input elements
               (imported from `scipy.special`)
   pade - Pade approximation to function as the ratio of two polynomials.
          (imported from `scipy.interpolate`)
   info - Get help information for a function, class, or module. (imported from `numpy`)
   source - Print function source code. (imported from `numpy`)
   who - Print the Numpy arrays in the given dictionary. (imported from `numpy`)
