Computer Graphics Research Project:Graphics Compatibility System (GCS) Programmer's Reference Manual (Version 2.5).

摘要

The document represents one of a trilogy of manuals designed to outline the scope of GCS in a form which may be readily assimilated by the user. This particular manual is intended for individuals who are already familiar with GCS but require instructions on the use of specific options and/or facilities. Each GCS user level subroutine is covered along with all of the available USET, UPSET options for that subroutine. There is a separate chapter which discusses the important concepts supported by each USET and UPSET option. The manual is intended to be a definite treatise on all of the capabilities and facilities available with GCS. For easy reference the subroutines are presented in alphabetical order within one chapter. The chapter also contains an index table at the beginning that further facilitates a quick reference option. Each example presented is intended to illustrate specific characteristics about functioning of a particular subroutine or option. It is impossible because of the inherent flexibility of GCS to describe all of the possible effects which can be obtained by the interaction of various options. Users are encouraged to use their imagination and experiment. (Modified author abstract)
