Updates on the screens

Posted by Saeed on May 30, 2001 at 10:43 PM

Hi,

I am writing a small application to export screens from one computer to another. I have my code working fine with a low performance. I am capturing screen from one machine and sending it to another via Java socket. And this process is done at a reguler interval of time. Since I am sending the full screen to the other machine, the size of the data being transffered through the network is always quite big which is causing delay on the receiving machine. I am looking for some way of comparing the new captured screen with the one, sent last time and trying to find if there is a difference. If I successfully acomplish this task, I would like to get the coordinates of updated portion of the screen, capturing just updated portion and sending it to the receiving machine. This way I would be able to reduce the network traffic and could get the updates rather quickly on the receiving machine. I would appreciate if anyone of you could share his approach and/or code with me to do achieve this goal.
