Abstract
A common programming interface for multiple types of document processing systems. An object interface is defined that includes properties, methods, and events that are applicable to multiple types of document processing systems. For a particular document processing system of a particular type, an instance of the object interface is established, and an application program controls overall operations of the document processing system by setting values of properties in the object interface, invoking methods in the object interface, and responding to events reported via the object interface. System specific track drivers handle system specific interface requirements and interact with an application program via an instance of the object interface. The single application programming interface promotes ease of development for application programs and some reuse of code.
