Java 通过套接字发送ImageIcon并加载到JPanel
我可以发送和加载到JPanel已经和一切工作完美时，是在同一台计算机上。 当它在另一台计算机（LAN）上，屏幕捕获速度慢，每秒发送一次数据（imageIcon）时，问题就出现了。。。发送它确实需要很多时间。“鼠标/键盘”控件在本地主机/局域网上运行良好，几乎是实时的。唯一的问题是屏幕截图：/有人能帮我改进FPS吗 此文件是服务器处理程序，它将图像屏幕作为对象发送Java 通过套接字发送ImageIcon并加载到JPanel,java,swing,sockets,javax.imageio,event-dispatch-thread,Java,Swing,Sockets,Javax.imageio,Event Dispatch Thread,我可以发送和加载到JPanel已经和一切工作完美时，是在同一台计算机上。 当它在另一台计算机（LAN）上，屏幕捕获速度慢，每秒发送一次数据（imageIcon）时，问题就出现了。。。发送它确实需要很多时间。“鼠标/键盘”控件在本地主机/局域网上运行良好，几乎是实时的。唯一的问题是屏幕截图：/有人能帮我改进FPS吗 此文件是服务器处理程序，它将图像屏幕作为对象发送 Socket Client = null; Robot Robot = null; Rectangle Rectangle = nul

有一件事。。。我以前确实使用过这种方法，而且没有问题，现在唯一的区别是服务器（是一个程序）和客户端是一个加载到浏览器中的小程序…为了更快地获得更好的帮助，请发布一个。另外，代码似乎试图发送
