:pyPyAccess Module

The :pyPyAccess module provides a CFFI/Python implementation of the 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.

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)
