bower install --save is-xcf

Usage

Node.js

var fs = require('fs');
var isXCF = require('is-xcf');
var buffer = fs.readFileSync('awesome.xcf');

isXCF(buffer); // returns true

Browser

var xhr = new XMLHttpRequest();
xhr.open('GET', 'awesome.xcf');
xhr.responseType = 'arraybuffer';

xhr.onload = function () {
  isXCF(new Uint8Array(this.response)); // returns true
};

xhr.send();

API

isXCF(buffer)

Accepts a Buffer or Unit8Array.

Only needs the first 8 bytes, more is fine though.
