如何将网站的 HTML 转换为图像?

有人知道怎么做吗?我试过 JEditorPane 但它不起作用?还有其他想法吗?

Does anyone know how to do this? I've tried with JEditorPane but it does not work? Any other idea?

提前致谢.

这是我正在使用的代码:

This is the code I'm using:

import java.awt.Dimension;
import java.awt.Graphics2D;
import java.awt.image.BufferedImage;
import java.io.File;

import javax.imageio.ImageIO;
import javax.swing.JEditorPane;
import javax.swing.JFrame;
import javax.swing.SwingUtilities;

public class HtmlToImage
    {

        protected static File generateOutput() throws Exception
        {
            // Create a temporary output file for the PNG image.
            File outputFile =  new File("Reporte.png");
            outputFile.deleteOnExit();

            JEditorPane pane = new JEditorPane();
            pane.setContentType("text/html");
            pane.setPage("http://www.google.com");
            final JFrame frame = new JFrame();
            frame.pack();

            // Time Delay for the correct loading of the file.
            try
            {
                Thread.sleep(5000);
            }
            catch(NumberFormatException nfe)
            {
            }

            frame.add(pane);
            frame.pack();

            Dimension prefSize = pane.getPreferredSize();
            pane.setSize(prefSize);

            BufferedImage img = new BufferedImage(  prefSize.width, prefSize.height,
                                                  BufferedImage.TYPE_INT_RGB);
            Graphics2D g = (Graphics2D) img.getGraphics();

            SwingUtilities.paintComponent(g, pane, frame, 0, 0, prefSize.width, prefSize.height);

            ImageIO.write(img, "png", outputFile);

            return outputFile;
        }

        public static void main(String[] args)
        {
            try
            {               
                generateOutput();
            }
            catch (Exception e)
            {
                e.printStackTrace();
            }
        }

    }
