Method of creating and detecting device independent controls in a presentation data stream

摘要

A method of creating a graphical presentation data stream having special controls/hints which are device independent and permit text to be processed at higher speeds. The special controls/hints are added to the graphical presentation data stream to identify where limitations have been made for text presentation. A begin data characteristic control is added to the graphical presentation data stream to indicate the start of limitations. The limitations remain in effect until an associated end data characteristic control is encountered. An identification field is part of each begin/end characteristic control. The identification field defines the specific process used to generate the delimited portion of the data stream.
