Abstract

We have integrated digital video into Trestle, an object-oriented user interface toolkit written in Modula-3. The display of video frames is managed within the application process using, where possible, shared memory to transmit images to the window system. We took advantage of Modula-3's type system, lightweight threads and garbage collection to develop a flexible architecture that supports the reuse of image data within an application; the object-oriented features of Modula-3 we found most useful were inheritance, partial revelations, and encapsulation. We then integrated our video extension into several higher-level tools which allow us to dynamically experiment with video applications.
