Check if a Buffer/Uint8Array is an XCF image
Inspired by sindresorhus and his wonderful repos like is-gif.
npm install --save is-xcf
bower install --save is-xcf
var fs = require('fs');
var isXCF = require('is-xcf');
var buffer = fs.readFileSync('awesome.xcf');
isXCF(buffer); // returns true
var xhr = new XMLHttpRequest();
xhr.open('GET', 'awesome.xcf');
xhr.responseType = 'arraybuffer';
xhr.onload = function () {
isXCF(new Uint8Array(this.response)); // returns true
};
xhr.send();
Accepts a Buffer or Unit8Array.
Only needs the first 8 bytes, more is fine though.
