ABSTRACT:: 

Pixel Data Access is an interprocess communication technique that enables 
users of graphical user interfaces to automate certain tasks.  By accessing 
the contents of the display buffer, users can search for pixel representations 
of interface elements, and then initiate actions such as mouse clicks and 
keyboard entries.   While this technique has limitations it offers users of 
current systems some unusually powerful features that are especially appealing 
in the area of end-user programming.
