dynamic-image
dynamic-image was created to help assist media developers by dynamically creating their assets from a known-good master.
Configuration
Environment Variables
PHP_DIRECTORY_OVERLAYS- path to overlays (default/mnt/overlays)PHP_DIRECTORY_IMAGES- path to images (default:/mnt/images)
Example
Best run in containers, the idea is to use it as a CDN or image hosting server.
$ cd deployments
$ docker-compose up
Upload a full-size master:
http://localhost:8000/subfolder/rainbow-full.jpg
Then, in your front-end, call the image manipulation as you see fit:
http://localhost:8000/subfolder/rainbow-full.jpg?width=640&blur=5&overlay=cancelled&gravity=southwest
There is no need to upload X number of masters at different resolutions, just generate it.
With the internal php cache, the second view of the same parameters is served nice and quick. You can optionally disable the internal php cache and use caching on the front-end in nginx if you prefer.
