A node app to grab images from the internet and resize, crop and compress them. Uses GraphicsMagick (default) or Imagemagick.
Install using GraphicsMagick
$ brew install graphicsmagick
$ node app.js --p 8080
Install using ImageMagick
$ brew install imagemagick
$ node app.js --port 8080 --imagemagick
Call the service like this
http://localhost:8080/{resizeWidth}/{resizeHeight}?crop={cropWidth},{cropHeight},{x},{y}&url={url}
example
The following URL will get the image at http://etc/etc/image.jpg
http://localhost:8080/200/400?crop=100,100,250,150&url=htp://etc/etc/image.jpg
and will crop a 100px x 100px square at coordinates x=250px, y=150px. The cropped image will then be resized to 200px x 400px.
crop is an optional param. To crop without resizing, set the the resize dimensions to 0.
