The following JavaScript code will help you convert any web URL into a PNG image from the command line. The script renders the page using Webkit, the same engine that’s used inside Google Chrome and Apple Safari browser. See demo at ctrlq.org/screenshots.
var system = require('system'); // Web Address (URL) of the page to capture var url = system.args[1]; // File name of the captured image var file = system.args[2] + ".png"; var page = require('webpage').create(); // Browser size - height and width in pixels // Change the viewport to 480x320 to emulate the iPhone page.viewportSize = { width: 1200, height : 800 }; // Set the User Agent String // You can change it to iPad or Android for mobile screenshots page.settings.userAgent = "Mozilla/5.0 (Windows NT 6.1) AppleWebKit/536.5 (KHTML, like Gecko) Chrome/19.0.1084.56 Safari/536.5"; // Render the screenshot image page.open ( url, function ( status ) { if ( status !== "success") { console.log("Could not open web page : " + url); phantom.exit(); } else { window.setTimeout ( function() { page.render(file); console.log("Download the screenshot : " + file); phantom.exit(); }, 1000); } });
