Image Processor using Node Streams

------------------------------------

This library processes images by passing a readabale stream (or file paths) and writes it into a writable stream. It uses jpegtran for jpg methods, optipng and gifsicle-stream for optimizing png & gif files, respectively. The current fallback for PNG and GIF operations uses gm.

``
npm install --save image-processor
`

`javascript
var ImageProcessor = require('image-processor'),
rs = fs.createReadStream('photos/batman.gif'),
photo = 'photos/photo2.jpg';

// Accept a readable stream
var imageProcessor = new ImageProcessor(rs);

// Accept a file path
var imageProcessorFilePath = new ImageProcessor(photo);

//Configure options
//See API below to properly configure options per method
var opts = { interlaced: true, arithmetic: true };

imageProcessor.optimize(opts, function (err, data) {
if (err) {
console.error(err);
}

res.send(data);
});
