fastphotoapi's Introduction

FastPhotoAPI

An efficient, flexible, flask-based image server that uses lanczos resampling to serve optimized cached photos.

python3.12 -m venv fast_photo_venv
source fast_photo_venv/bin/activate
pip install -r requirements.txt

Usage:

Fetch a resampled & cached image /image/<yourimage>
Fetch the original, unmodified image /full/<yourimage>

Structure:

This application adopts the factory pattern; flask run instantiates the built-in development server by executing create_app() at the root of the app/ package, while python application.py creates a new production application, served by waitress.
