Gamo

An image proxy and optimization server. Like Camo, and compatible with Camo, but running proxied images through optimization, and with added functionality to resize them to specified dimensions using the URL path.

It expects to run behind a reverse proxy like Nginx or Varnish which would perform caching. By itself, it makes no attempt to do so.

URL structure:

/[HMAC]/[Hex-encoded URL]

Optionally:

/[HMAC]/[Hex-encoded URL]/[Dimensions]

The dimensions are to be given as a single integer as one side of a square. The image will be resized proportionally to fit within the total number of pixels.

Arbitrary dimensions cannot be used. Pre-determined values are configured through the command-line invocation.

Usage:

gamo --key=SHARED_HMAC_SECRET --bind=127.0.0.1:8081 --dimensions=256,512,1024
