Using Wand on Heroku

Add Wand into requirements.txt file, and simply import wand. It would just work. (See requirements.txt in this repository.)

app.py

from os import environ

from flask import Flask
from wand.image import Image


app = Flask(__name__)


@app.route('/')
def hi():
    with Image(filename='iu.jpg')  as i:
        return 'width: {0}, height: {1}'.format(i.width, i.height)


if __name__ == '__main__':
    app.run(host='0.0.0.0', port=int(environ.get('PORT', 5000)))
