	var canvas = document.createElement('canvas'),
	context = canvas.getContext && canvas.getContext('2d'),
	rgb = {r:102,g:102,b:102}, // Set a base colour as a fallback for non-compliant browsers

	count = 0,
	i = -4,
	data, length;

	// return the base colour for non-compliant browsers

	pragma solidity ^0.4.11;
