Abstract

This research report describes the design of a highlevel graphics package for use by application programmers t o display pictures of two-dimensional objects on a portable alphanumeric/graphic terminal. The design is implemented on the Digital VAX-11/780™ minicomputer running under the VMS operating system environment as the host computer and uses the DECwriter Correspondent (LA12) as the graphics device. The graphics package consists both the database manipulation software which is completely device dependent, and the interface software between the normal "drawing functions" and the hardware associated with a particular graphics device, which is minimally device-dependent.
