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. KEYWORDS: End-User Programming, Programming by Example, Pixel Data Access, Interprocess Communication, Graphical Macros. INTRODUCTION Users of many systems appreciate the power they have to create novel automations that extend the power of these systems. Macros in word processors such as Emacs, WordPerfect, and Word enable users to record frequent sequences of actions for repeated replay and save them for future use. Macros can automate tasks such as making back-up files, merging complex lists, or con...
