img-workshop v0.2.1

img-workshop

This is a simple helper library to dynamically process images. It watches an input folder (or fileglob), applies some arbitrary processing to each image, and saves the result in an output folder. Whenever one of the source files changes, the processing is re-applied.

Installation

brew install graphicsmagick
npm install img-workshop

Usage

To invoke from code:

var watch = require('img-workshop')
var gm = require('gm')

var input = './inputs/**/*.png'      // file, folder, or glob
var output = './outputs/'            // folder
var proc = function(path) {
    var img = gm(path)
        .blur(5)
        .flip()                      // or whatever
        .clip()
    return img
}

watch( input, output, proc )

To use as an ad-hoc standalone library:

• Open index.js and edit the INPUT and OUTPUT settings
• Open processor.js and fill in whatever image processing you want
• run npm start from the project folder

Either way, image processing is done with gm, a node wrapper for graphicsmagick.
