html转为图片(二)：Cobra

• Cobra 是一个纯 Java 的HTML 解析和生成器，支持 HTML 4 、JavaScript、CSS 2
• 这个方法的依赖包，暂时我没找到相应的版本，所以我就没测试
• 案例：

public class Cobra {
    public static void main(String[] args) throws Exception {
        JFrame window = new JFrame();
        HtmlPanel panel = new HtmlPanel();
        window.getContentPane().add(panel);
        window.setSize(600, 400);
        window.setVisible(true);
        new SimpleHtmlRendererContext(panel, new SimpleUserAgentContext())
                .navigate("http://www.hefeipet.com/client/chongwuzhishi/shenghuozatan/2012/0220/95.html");

        BufferedImage image = new BufferedImage(panel.getWidth(),
                panel.getHeight(), BufferedImage.TYPE_INT_ARGB);

        // paint the editor onto the image
        SwingUtilities.paintComponent(image.createGraphics(), panel,
                new JPanel(), 0, 0, image.getWidth(), image.getHeight());
        // save the image to file
        ImageIO.write((RenderedImage) image, "png", new File("html.png"));
    }

}
