COMPUTER GRAPHICS BY EXAMPLE, PART 7: THE TV80LIB GRAPHICS LIBRARY

摘要

TV80LIB is a FORTRAN library of graphics subroutines and device processors. TV80LIB routines are device-independent in that all picture- drawing calls are independent of the particular output device being used. This report, written for the new user, shows by example how to use TV80LIB with CHAT (the compiler for the LRLTRAN language). All libraries used (and the CHAT compiler as well) are available in public files on the CDC 7600 computers of the Livermore Octopus Network. The examples help to illustrate the use of device processors, drawing routines, and color selection with TV80LIB in an LRLTRAN source program.
