: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)
|
