DIGLIB for HP-1000 computers
DIGLIB (Device Independent Graphic LIBrary), originally developed by Hal R. Brand for DEC computers, has been modified for use by HP 1000 computers running under RTE. DIGLIB consists of a small but functionally complete set of FORTRAN-callable library subroutines for creating arbitrary views of two-dimensional objects and for supporting interaction between the graphic application program and its user. Graphic presentation is oriented towards interactive graphic display devices (such as the HP 2648A or Tektronix 4025) and line-drawing plotters (like the CalComp pen plotters). In addition, a high density Versatec V-80 or 1200 electrostatic printer/plotter interface is available. DIGLIB makes the application program independent of the specific graphic hardware devices, thereby presenting a uniform programmer interface to the graphics library, requiring few modifications (typically one) to the application program in order to accommodate a different graphics configuration. A device-independent subroutine library provides a high level of program portability, allowing support of a variety of different display controllers and operating environments.
