读取二值图像

我已经启动并运行了套接字通信。

我现在需要以下方面的帮助：

我们将通过套接字将图像发送到设备。

transmit.framebuffer.rgb_byte will transmit in binary format the following information:
[4 bytes] => image width
[4 bytes] => image height
[< image width> * <image height> * 3 bytes] => RGB in unsigned char format [0, 255]
[3 bytes] "OK\n"

我该如何让它发挥作用？... 现在我只处理纯文本等，所以这整个二进制编码对我来说是新的。

I've got my socket communication up and running.

I now need help with the following:

We are going to send a image to the device through the socket.

transmit.framebuffer.rgb_byte will transmit in binary format the following information:
[4 bytes] => image width
[4 bytes] => image height
[< image width> * <image height> * 3 bytes] => RGB in unsigned char format [0, 255]
[3 bytes] "OK\n"

How would I go about getting this to work?..
For now I've just worked with plain text etc,
so this whole binary coding is new to me.

这是您可以在客户端读取数据的示例：

out = new ByteArrayOutputStream();
in = new BufferedInputStream(socket.getInputStream(), BUFFER_SIZE);
byte[] dataBuffer = new byte[1024 * 16];
int size = 0;
while ((size = in.read(dataBuffer)) != -1) {
    out.write(dataBuffer, 0, size);
}
out.flush();
byte[] bytesReceived = out.toByteArray();

This is an example of you could read data on the client side:

out = new ByteArrayOutputStream();
in = new BufferedInputStream(socket.getInputStream(), BUFFER_SIZE);
byte[] dataBuffer = new byte[1024 * 16];
int size = 0;
while ((size = in.read(dataBuffer)) != -1) {
    out.write(dataBuffer, 0, size);
}
out.flush();
byte[] bytesReceived = out.toByteArray();
