| :py:mod:`PyAccess` Module
 | |
| =========================
 | |
| 
 | |
| The :py:mod:`PyAccess` module provides a CFFI/Python implementation of the :ref:`PixelAccess`. This implementation is far faster on PyPy than the PixelAccess version.
 | |
| 
 | |
| .. note:: Accessing individual pixels is fairly slow. If you are
 | |
|            looping over all of the pixels in an image, there is likely
 | |
|            a faster way using other parts of the Pillow API.
 | |
| 
 | |
| Example
 | |
| -------
 | |
| 
 | |
| The following script loads an image, accesses one pixel from it, then changes it.
 | |
| 
 | |
| .. code-block:: python
 | |
|     
 | |
|     from PIL import Image
 | |
|     im = Image.open('hopper.jpg')
 | |
|     px = im.load()
 | |
|     print (px[4,4])
 | |
|     px[4,4] = (0,0,0)
 | |
|     print (px[4,4])
 | |
| 
 | |
| Results in the following::
 | |
| 
 | |
|     (23, 24, 68)
 | |
|     (0, 0, 0)
 | |
| 
 | |
|
