[原创]利用图片的像素RGB值还原图像的JAVA应用

    --sunfruit
    JAVA编写的使用像素RGB值还原图像的方法,代码如下
    public class ImageData {

    private int[][] idata=null;

    public ImageData() {
        readImageData();
        writeImageData();
    }

    private int[][] readImageData()
    {
        try {
            //imagedata的键值就是一个存储了图像像素RGB值得文本文件
            RandomAccessFile randomAccessFile = new RandomAccessFile(new File(GetResource.getXMLValue("imagedata")),"r");
            long filesize=randomAccessFile.length();
            long filepointer=0;
            DynArrayInt dynArrayInt=null;
            ArrayList arrayList=new ArrayList();
            int n1=0;
            while(filesize>filepointer)
            {
                filepointer=randomAccessFile.getFilePointer();

                String str1=randomAccessFile.readLine();
                if(str1!=null)
                {
                    String[] str2=str1.split(" ");
                    String[] str3=str2[1].split(",");
                    dynArrayInt=new DynArrayInt();
                    for(int i=0;i<str3.length;i++)
                    {
                        if(!str3[i].equals(""))
                        {
                            int pix = Integer.parseInt(str3[i], 16);
                            dynArrayInt.addInt(pix);
                        }
                    }
                    if(n1==0)
                        n1=dynArrayInt.getSize();
                    arrayList.add(dynArrayInt);
                }
            }

            idata=new int[arrayList.size()][dynArrayInt.getSize()];
            for(int i=0;i<idata.length;i++)
            {
                 DynArrayInt dynArrayInt1=(DynArrayInt)arrayList.get(i);
                for(int j=0;j<idata[i].length;j++)
                {
                    idata[i][j]=dynArrayInt1.getInt(j);
                }
            }

        } catch (Exception ex) {
            ex.printStackTrace();
        }
        return idata;
    }

    private void writeImageData()
    {
        BufferedImage bufferedImage=new BufferedImage(idata[0].length,idata.length,BufferedImage.TYPE_INT_RGB);
        for(int i=0;i<idata.length;i++)
        {

            for(int j=0;j<idata[i].length;j++)
            {
                bufferedImage.setRGB(j,i,idata[i][j]);
            }
        }
        Random random=new Random(System.currentTimeMillis());
        String ext="jpg";
        String filepath = System.getProperty("java.io.tmpdir") + random.nextInt(99999) + "." + ext;
        try {
            ImageIO.write(bufferedImage, ext,  new File(filepath));
            System.out.println("文件已经生成,路经为" + filepath);
        }
        catch (IOException ex) {
            ex.printStackTrace();
        }

    }

    public static void main(String[] args) {
        ImageData imagedata = new ImageData();
    }
}

其中的“GetResource”,“DynArrayInt”为自定义类,GetResource得功能就是解析获取properties文件的内容,DynArrayInt是一个整形动态数组,可以在以前的文章里获得“DynArrayInt”的源代码,所谓的图像的像素值就是如下数据

以上数据表示图像有两行像素,每一行有260个像素组成,每个像素的RGB值就是44525b

非常感谢SF的帮忙,解决这个问题。其实这个问题起源于解决自拍截图的图片保存。现在很多网站都兴起自拍视频方面的,我看了很多都是php完成的,这次特此采用java实现。  回复  更多评论

您好 我想参考下你的代码 但其中的“GetResource”,“DynArrayInt”我找了您的博客,但一直没找到,请博主告知下具体位置,非常感谢~  回复  更多评论
