问题
I'm trying to blur an image with Pillow, using the ImageFilter as follows:
from PIL import ImageFilter
blurred_image = im.filter(ImageFilter.BLUR)
This works fine, except that it has a set radius which is way too small for me. I want to blur the image so much that it can be barely recognised anymore. In the docs I see that the radius is set to 2 by default, but I don't really understand how I can set it to a larger value?
Does anybody have any idea how I could increase the blur radius with Pillow? All tips are welcome!
回答1:
Image.filter() takes an ImageFilter so you can create an ImageFilter.GaussianBlur instance with whatever radius you want, passed in as a named argument.
blurred_image = im.filter(ImageFilter.GaussianBlur(radius=50))
You can even make it more concise like so:
blurred_image = im.filter(ImageFilter.GaussianBlur(50))
