WORK IN PROGRESS

NodeSizer

Caching ImageResizingProxy service running in node js.

Server designed to provide a nice way of requesting images on the internet at a size you want. Designed and built in Node JS. It's none blocking, so rolled on out on a CDN/Cloud will scale uniformly.

Currently supports

bold denotes required.

• source= the source file anywhere on the internet. (WebAddress)
• size= single or widthxheight e.g. '240' (finds the largest side) '240x360' will do it exact.
• ext= png,jpg,gif,tiff
• quality= 1-100 defaults to 80 only works on jpeg, does a default 7 pass png optimisation.

An example request looks like http://localhost:8080/convert?size=240&source=http://yoursite.com/media/yourimage.png

Headers

• 1.0.1 - Content-Creation-Time : [elapsed] (Returns how long it took to create/return the image for you)
