Python uses the PIL library to blur the picture Gaussian

First, install the PIL

PIL is the Python Imaging library abbreviation for processing pictures. PIL has a Gaussian blur processing class, but there is a bug (the latest 1.1.7bug still exists), that is, the fuzzy radius of the dead is 2, cannot be set. On the 160th line of source imagefilter.py:

So, we can change it here by ourselves OK.

Second, the revised Code

The code is as follows:

#-*-coding:utf-8-*- fromPILImportImage, ImageFilter

classMygaussianblur (imagefilter.filter): Name="Gaussianblur"    def __init__(Self, radius=2, bounds=None): Self.radius=radius self.bounds=boundsdeffilter (self, image):ifself.bounds:clips=Image.crop (self.bounds). Gaussian_blur (Self.radius) image.paste (clips, self.bounds)returnImageElse:            returnImage.gaussian_blur (Self.radius)

Third, call

' demo.jpg '  'demo_blur.jpg'== Image.filter (Mygaussianblur (radius= )) Image.Save (dimg)print'success'

If you only need to work with an area, pass in the bounds parameter

Four, the effect
