wip: This is work in progress. Converting to use generators and graphicsmagick-stream library. The uploading is handled by pkgcloud. The master branch and 1.0.0-alpha1 tag works only with s3.
Please use [email protected] which is stable. The 1.0.0-alpha releases are unstable and not recommended for production.
A node module to resize, crop and upload images (with different variants and presets) to the cloud.
- node >= 0.11.12 with
--harmonyflag - You need to install libgraphicsmagicks.
Using osx
$ brew install graphicsmagick --build-from-sourceUsing ubuntu
$ sudo apt-get install libgraphicsmagick1-dev$ npm install imagerUse a config file. For example imager-config.js
exports.variants = {
item: { // variant
thumb: { // preset
options: { // preset options
pool: 5,
scale: { width: 200, height: 150, type: 'contain' },
crop: { width: 200, height: 150, x: 0, y: 0 },
format: 'png',
rotate: 'auto',
}
},
large: {
original: true // upload original image without image processing
}
},
gallery: {
// ...
}
};In the above config, item and gallery are variants. thumb and large are presets. Each preset has an options object which is a graphicsmagick-stream config object.
-
options- An object that is passed to graphicsmagick. See what options are available here -
rename- A function that accepts an objectfileas an argument. It has the following properties:name,size,typeandpath. It is called before uploading each file.Example:
variants.item.thumb.rename = function (file) { return 'users/1/thumb/' + file.name; }; var imager = new Imager(variants.item, ...);
-
original- A true value. If this option is set, the original image will be uploaded without any image processing.

});files is an array of files or a single file. A file should be the file name of the image on the storage. callback accepts err as an argument.
