偶然在网上看到一个.net的将图片转成html代码的方法，想来java也可以轻松实现。遂试之....

import java.awt.image.BufferedImage;
import java.awt.image.ColorModel;
import java.awt.image.Raster;
import java.io.BufferedWriter;
import java.io.File;
import java.io.FileWriter;
 
import javax.imageio.ImageIO;
 
public class Image2Html {
 
    public static void main(String[] args) throws Exception {
        File file = new File("E:\\Desert.jpg");
        File destFile = new File("E:\\image.html");
        BufferedWriter bos = new BufferedWriter(new FileWriter(destFile));
        BufferedImage image = ImageIO.read(file);
        Raster raster = image.getData();
        int height = raster.getHeight();
        int width = raster.getWidth();
        // ColorModel model = image.getColorModel();
        ColorModel model = ColorModel.getRGBdefault();
        bos.write("<html><head>");
        bos.write("<style>");
        bos.write("#pic {width:" + width + "px;height:" + height + "px;}");
        bos.write("#pic div{float:left;height:1px;overflow:hidden;width:1px;}");
        bos.write("</style>");
        bos.write("</head>");
        bos.write("<body><div id=\"pic\">");
        StringBuilder sb = new StringBuilder();
        for (int i = 0; i < width; i++) {
            sb.delete(0, sb.length());
            for (int j = 0; j < height; j++) {
                int rgb = image.getRGB(i, j);
                int r = model.getRed(rgb);
                int g = model.getGreen(rgb);
                int b = model.getBlue(rgb);
                sb.append("<div style=\"background:#")
                        .append(Integer.toHexString(r))
                        .append(Integer.toHexString(g))
                        .append(Integer.toHexString(b)).append(";\"></div>");
                // int newRgb = model.getRGB(rgb);
                // System.out.print(Integer.toHexString(newRgb) + " ");
            }
            bos.write(sb.toString());
        }
        bos.write("</div></body></html>");
        bos.close();
    }
}

注意：图片不能太大，否则会显示不出来。性能有大问题，目测娱乐下还是可以。
