imgix Adapter

Adapter from home-grown image manipulation to imgix.

The script responds to requests to legacy URLs, generates an imgix URL to process the image then caches the retrieved image locally.

Example

A request to:

http://imgix-adapter.example/path/to/script/public/c100x50/uploaded-images/myimage.jpg

Retrieves an image from:

http://imgix-domain.imgix.net/uploaded-images/myimage.jpg?fit=crop&w=100&h=50

And caches the image locally at:

/path/to/script/public/c100x50/uploaded-images/myimage.jpg

Where:

• c defines the resize fit mode and is either c for crop or r for clip
• 100 is the output width
• 50 is the output height
• uploaded-images/myimage.jpg is the path to the image

In addition, trim=color is used to trim the edges of the image. You MUST also provide a sign key which is used to secure the image request.
