I'm writing an application which takes continous screenshots of a small portion of the screen. What I would like to do is to display some type of indication over the targeted area which will allow the user to see where the capture is taking place. It's an application which will display a person's workspace in real time on the web and the user needs to know in which are they must work in order for the images to be captured correctly.
Does anybody have any idea in particular on how to accomplish this? The java application that is doing the capturing will be running in the background and the applications being captured could be anything just as long as there is some type of indication to the user where the space is. I imagine a solution to this is going to be kind of tricky.
