HTML转图片
PhantomJS
NodeJS+PhantomJS抓取页面信息以及截图http://www.cnblogs.com/justany/p/3279717.html
PhantomJS1.7APIhttp://www.cnblogs.com/ziyunfei/archive/2012/09/28/2705369.html
配置:Linux把PhantomJS加入到环境变量，window的直接运行exe文件。
利用phantomjs+casperjs实现登陆抓取网页并截图http://my.oschina.net/jiuxiaoyao/blog/148456
利用phantomjs将HTML源代码转换成图片http://neoremind.net/2013/02/%E5%88%A9%E7%94%A8phantomjs%E5%B0%86html%E6%BA%90%E4%BB%A3%E7%A0%81%E8%BD%AC%E6%8D%A2%E6%88%90%E5%9B%BE%E7%89%87/
PhantomJS是一个无界面的WebKit浏览器引擎,还有配套的JavaScriptAPI.它原生支持各种web标准技术:DOM处理,CSS选择器,JSON,Canvas,以及SVG.
通常我们的需求是将网页渲染成图片保存，那么也会有这样的情况，将HTML源代码转换成图片，下面的代码将满足需求：
var webpage = require('webpage')
, page = webpage.create();
page.viewportSize = { width: 1024, height: 800 };
page.clipRect = { top: 0, left: 0, width: 1024, height: 800 };
page.settings = {
javascriptEnabled: false,
loadImages: true,
userAgent: 'Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.31 (KHTML, like Gecko) PhantomJS/19.0'
};
page.open('http://neoremind.net/2013/02/%E5%88%A9%E7%94%A8phantomjs%E5%B0%86html%E6%BA%90%E4%BB%A3%E7%A0%81%E8%BD%AC%E6%8D%A2%E6%88%90%E5%9B%BE%E7%89%87/', function (status) {
var data;
if (status === 'fail') {
console.log('open page fail!');
} else {
page.render('./snapshot/test.png');
}
// release the memory
page.close();
phantom.exit();
});保存成texttoimage.js
运行：phantomjstexttoimage.js
图片保存到newimage.png中
无需浏览器执行Javascript脚本：SlimerJShttp://www.open-open.com/lib/view/open1374371986777.html
SlimerJS能够利用Javascript脚本来操作一个网页。SlimerJS允许你在浏览器外执行javascript脚本。
SlimerJS用于做功能测试，页面自动化，网络监控，屏幕捕捉，等。
SlimerJS类似于PhantomJs，但它运行在Gecko之上。而SlimerJS采用MozillaFirefox浏览器引擎来代替Webkit。

这个还能截图，但是要打开一个新窗口。要是服务器没有安装浏览器，那它就无能为力了。

java网页快照-网页转存为图片实现代码http://www.111cn.net/jsp/java/43586.htm
个人觉得免费的java实现方式，最方便的网页快照生成方式。可以生成大型网页的快照。非常棒！使用代码前需要导入jar包。需要三个jar包：swt-3.6M3-win32-win32-x86.jar，DJNativeSwing-SWT.jar,DJNativeSwing.jar
