本文介绍了一种使用Java将HTML转换为图片的方法，并演示了如何利用HtmlImageGenerator类加载HTML源码，将其保存为图片文件及生成包含客户端映射的HTML文件。

package com.ky.util;

import gui.ava.html.image.generator.HtmlImageGenerator;

public class Html2ImageTest {

       //此方法仅适用于JdK1.6及以上版本
//       Desktop.getDesktop().browse(new URL("http://google.com/intl/en/").toURI());
//       Robot robot = new Robot();
//       robot.delay(10000);
//       Dimension d = new Dimension(Toolkit.getDefaultToolkit().getScreenSize());
//       int width = (int) d.getWidth();
//       int height = (int) d.getHeight();
//       //最大化浏览器
//       robot.keyRelease(KeyEvent.VK_F11);
//       robot.delay(2000);
//       Image image = robot.createScreenCapture(new Rectangle(0, 0, width,
//        height));
//       BufferedImage bi = new BufferedImage(width, height,
//        BufferedImage.TYPE_INT_RGB);
//       Graphics g = bi.createGraphics();
//       g.drawImage(image, 0, 0, width, height, null);
//       //保存图片
//       ImageIO.write(bi, "jpg", new File("D://google.jpg"));

public static void main(String[] args){

HtmlImageGenerator imageGenerator = new HtmlImageGenerator();

String htmlstr = "<table width='654' cellpadding='0' cellspacing='0' bordercolor='#FFFFFF'><tr><td><img src='http://www.apkfather.com/yhqserver/images/mdl.jpg'/></td><td><img src='http://www.apkfather.com/yhqserver/images/mdl.jpg'/></td><td><img src='http://www.apkfather.com/yhqserver/images/mdl.jpg'/></td></tr><tr><td><img src='http://www.apkfather.com/yhqserver/images/mdl.jpg'/></td><td><img src='http://www.apkfather.com/yhqserver/images/mdl.jpg'/></td><td><img src='http://www.apkfather.com/yhqserver/images/mdl.jpg'/></td></tr><tr><td><img src='http://www.apkfather.com/yhqserver/images/mdl.jpg'/></td><td><img src='http://www.apkfather.com/yhqserver/images/mdl.jpg'/></td><td><img src='http://www.apkfather.com/yhqserver/images/mdl.jpg'/></td></tr><tr><td><img src='http://www.apkfather.com/yhqserver/images/mdl.jpg'/></td></tr></table>";

imageGenerator.loadHtml(htmlstr);

imageGenerator.getBufferedImage();

imageGenerator.saveAsImage("d:/hello-world.png");

imageGenerator.saveAsHtmlWithMap("hello-world.html", "hello-world.png");

}
