Abstract : This report describes a digital plotting system that receives and stores coded signals depicting graphic information for processing and display. The system processes three basic types of information which are short vector information, long vector information and character information. Together these three types of information can reproduce virtually any type of graphic information that is desired to be transmitted and displayed. The short vector information describes curved lines, the long vector information describes straight lines and the character information describes alphanumerics and symbols. The system employs effective data compaction techniques resulting in a substantial reduction of processed data as compared to facsimile processing. The system automatically stores and provides for sequential selection of the short vector, long vector and alphanumeric information for presentation.
