Abstract
Abstract A method is disclosed for nesting and processing mixed data objects from diverse data types including: text, image, and graphics. The method permits the utilization of shared environmental specifications for processing multiple data objects. Each mixed data object includes a pair of object delimiters, which identify the beginning and end of that object, and an environment control indicator which determines whether that object will inherit environment objects from a nesting object or pass environment objects to the nesting object. An appropriate application for processing each object is called in response to the detection of the beginning of that object and is returned to after any intervening objects have been processed. Processing is accomplished utilizing environment elements from the current object or a previous object so that coordinate systems, color, units of measure or current positions may be shared between objects while allowing specific applications suited to a particular object to be utilized for processing.
