Micro application to serve images with customized cropping

Project description

A simple micro application to serve images with customized cropping True ecce homo

Introduction

This micro application resizes existing images according to given query parameters. The application returns the image and saves the image as the previous filename suffixed with the query params. The intended usage is with a file server which will return this new image the second time when the url matches the new filename.

E.g. for an existing image image.jpg we use image.jpg?w=200 to set the width to 200 and save the new file as image.jpg?w=200

Configuration

The settings are read from environment variables. #### ECCEOMO_MEDIA_ROOT The absolute path to the root directory common to all media files. e.g. export ECCEHOMO_MEDIA_ROOT='/www/media' #### ECCEHOMO_MEDIA_URL Optional URL between domain and filename. e.g. export ECCEHOMO_MEDIA_URL='media' #### ECCEHOMO_DEFAULT_METHOD Set to contain if left unset. Defines a default method to use when height h and width w are specified with a without a method t. e.g. export ECCEHOMO_DEFAULT_METHOD='crop' #### ECCEHOMO_MINIMUM_LENGTH Sets a minimum accepted length for the width w and height h parameters. e.g. export ECCEHOMO_MINIMUM_LEGNTH=10 ## Usage There are three query parameters. Height h, Width, w, and method type t. Method defintions in python-resize-image readme

They should be used always in the same order as the filename will be saved with the querystring as part of its filename.
With example values given.
Resize width:
?w=100
Resize height:
?h=100
Resize default e.g. contain:
?w=100&h=50
Resize crop:
?w=100&h=50&t=crop
Resize thumbnail:
?w=100&h=50&t=thumbnail
Resize cover:
?w=100&h=50&t=cover
## Notes: ## Files are saved with url path as filename. If trailing slash present in url will be removed for filename {domain}/{media_url}/path/to/file.jpg/?w=100 -> {media_directory}/path/to/file.jpg?w=100
