JAVA編寫的使用像素RGB值還原圖像的方法，代碼如下
public class ImageData {
private int[][] idata=null;
public ImageData() {
readImageData();
writeImageData();
}
private int[][] readImageData()
{
try {
//imagedata的鍵值就是一個存儲了圖像像素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("文件已經生成，路經為" + filepath);
}
catch (IOException ex) {
ex.printStackTrace();
}
}
public static void main(String[] args) {
ImageData imagedata = new ImageData();
}
}
其中的“GetResource”，“DynArrayInt”為自定義類，GetResource得功能就是解析獲取properties文件的內容，DynArrayInt是一個整形動態數組，可以在以前的文章里獲得“DynArrayInt”的源代碼,所謂的圖像的像素值就是如下數據

以上數據表示圖像有兩行像素，每一行有260個像素組成，每個像素的RGB值就是44525b
