blurhash-python

This is an encoder for the BlurHash algorithm. To find out more about BlurHash, see https://github.com/woltapp/blurhash.

Installation

Install blurhash with pip

$ pip install blurhash-python

or pipenv

$ pipenv install blurhash-python

Usage

Create blurhash from image file

import blurhash

with open('image.jpg', 'rb') as image_file:
    hash = blurhash.encode(image_file, x_components=4, y_components=3)

Alternatively, scale the image to produce a faster hash, and create a blurhash from the in-memory image directly

import blurhash
from PIL import Image

with Image.open('image.jpg') as image:
  image.thumbnail(( 100, 100 ))
  hash = blurhash.encode(image, x_components=4, y_components=3)

You can also pass file name as parameter to the function

import blurhash

hash = blurhash.encode('image.jpg', x_components=4, y_components=3)

y_components and x_components parameters adjust the amount of vertical and horizontal AC components in hashed image. Both parameters must be >= 1 and <= 9.
