Making a Banner Generator With Pillow and Flask
Blog post from Pybites
The article describes the process of integrating a previous Pillow script, banner.py, into a Flask app to create a PyBites Banner Generator, which is hosted on Heroku and available on GitHub for customization. Users can generate banners by providing a name, background URL, and text, with options to use specific logos when logged in. The app employs Pillow for image manipulation, Flask-WTF for form handling, and Flask-SQLAlchemy to store image parameters, while addressing Heroku's ephemeral filesystem by using PostgreSQL for persistent data storage. The core functionality is managed within a Python script, app.py, which handles form submissions, image generation, and caching, with the final output sent to the browser using Flask's send_file function. The article also invites readers to participate in the related Code Challenge, provides guidance on when to use Flask versus Django, and references additional resources for further exploration.
