:py:mod:`~PIL.ImageFilter` Module
|
|
=================================
|
|
|
|
The :py:mod:`~PIL.ImageFilter` module contains definitions for a pre-defined set of
|
|
filters, which can be be used with the :py:meth:`Image.filter()
|
|
<PIL.Image.Image.filter>` method.
|
|
|
|

|
|
|
|
from PIL import ImageFilter
|
|
|
|
im1 = im.filter(ImageFilter.BLUR)
|
|
|
|
im2 = im.filter(ImageFilter.MinFilter(3))
|
|
im3 = im.filter(ImageFilter.MinFilter) # same as MinFilter(3)
|
