如何通过套接字发送图像对象？

Question

我想通过套接字发送图像对象...不想将图像存储在发送者或接收者计算机中...

Answer 1

Use this method:

  ImageIO.write(RenderedImage, String, OutputStream)

Use in your situation:

Sender

   BufferedImage image = ....;
   ImageIO.write(image, "PNG", socket.getOutputStream());

Receiver

   BufferedImage image = ImageIO.read(socket.getInputStream());

Answer 2

So what have you tried ?

This is a tutorial on client/server communication using Java. This reads from stdin, but in your instance you should probably provide an InputStream on your image object.

Answer 3

将此序列化用于图像对象以通过套接字发送它。
