trippyshift
===========
This module takes a buffer holding an image and uses graphicsmagick to overlay an offset second copy of the image while applying the "Add" composite operator.
install:
```
npm install trippyshift --save
```
usage:
```
var fs = require('fs'),
trippyshift = require('trippyshift');
var wooo;
fs.readFile('./file.jpg', function (err, data) {
wooo = data;
trippyshift({}, data, writeToDestination);
});
function writeToDestination(err, trippedOutBuf) {
if (err) throw err;
fs.writeFileSync('./output.jpg', trippedOutBuf);
};
```
an `options` object with `shiftXMaxPercent` and/or shiftYMaxPercent can be passed in optionally as the first argument.
