Sending an Image

Question

Hello!
Usually, when I use networking (which is rare) PrintWriter fulfills my needs. But in this case I need to send a BufferedImage over a network, and I don't think PrintWriter would work. Does somebody know what class I could use?
Thanks!

Answer 1

I realize this. Here's the pseudo code of what I'm trying to accomplish:
1. Get the image to be sent.
2. Get the data as an array of bytes.
3. Use BufferedOutputStream to send the bytes.
The problem with my code is with #2. I can't seem to find a way to convert an image into an array of bytes. The above code is the closest I have ever gotten.
Any suggestions?
here my suggestion
1. get image from file or what?, if you want to get image from file then you should use fileInputStream like this :
public byte[] readFile(String fileName){
       ByteArrayOutputStream bos = new ByteArrayOutputStream();                   
        try{
            fis = new FileInputStream(sourceFile);
            int d;
            while((d=fis.read())!=-1){
               bos.write(d);               
            System.out.println("LOAD FILE COMPLETED");
        }catch (IOException e){
        //nothing to do
        }catch (StringIndexOutOfBoundsException e){
            System.out.println("BLA2");
        return bos.toByteArray();
   }2. then you can send bos that already come byteArray like this :
public void sendChunkFile(byte[] fileByte) {
        DataOutputStream os;
        int off = 0;
        boolean endFile = false;
        while (!endFile) {
            if ((off+chunkSize)>=fileSize) {
                endFile = true;
                chunkSize = fileSize - off;
                os.write(fileByte,off,chunkSize);
                off = off + chunkSize;    
                try {
                    Thread.sleep(100);
                } catch (InterruptedException e) {
        if (endFile){
            System.out.println("FILE Sent");
            chunkSize = CHUNK_SIZE;
   }maybe that will help you
