Galaxy Advanced Engineering, Inc. presents a migration bridge for callable DIGLIB
routines within your existing FORTRAN program via its high level FORTRAN Graphics Library Language
that is called UGL. UGL is a Scientific Graphics Subroutine Library for any computing
system such as Main, Micro and Mini-Computers with its given Operating System. UGL presently
supports hardware such as HP/UX, SUN/SOLARIS, Alpha/OpenVMS, VAX/VMS, LINUX SGI/IRIX and
Windows 95/98/2000 and NT or DOS.
GAE Graphics Software Products and DIGLIB Compatibility
UGL-GRAPHICS was developed to provide a migration path with a CA-DISSPLA, GKS, PLOT-10,
CalComp, PLOT88 and DIGLIB (from Lawrence Livermore Lab.) graphics interface in the PC
and VAX as well as UNIX environment and provides the same high graphics standards found
on the main frames using the above graphics libraries. The most common subset of CA-DISSPLA
routine (more than %95) and rest of the mentioned graphics libraries are supported directly and any
particular ones may be provided upon request. If the users have an existing code using any of these
graphics library routines within them, they do not have to change their calls. The bridge that are
built with UGL-GRAPHICS library of Galaxy advanced Engineering, Inc. will distinguish these
routines and maps them to its own routine against these calls for direct porting of the user code to
its new environment supported by UGL-GRAPHICS.
What is DIGLIB?
DIGLIB (Device Independent Graphics LIBrary) is a collection of FORTRAN callable subroutines
designed with the following goals:
PC-DIGLIB is a port of the popular graphics package DIGLIB written by Hal Brand at
Lawrence Livermore Lab. for use on PDP-11's and VAX's. The package has been ported to the PC
environment using above 16 bit Fortran Compilers.
- Easily usable by the casual graphics programmer for 2D plotting.
- Device independent (as much as possible).
- Small and reasonably fast.
- Device drivers are as simple as possible, and therefore easy to write, and device drivers may
be written in FORTRAN when desired.
- Compatible (as much as possible) with PLTLIB. This is a historical artifact that no one now
needs be concerned with except former PLTLIB users.
- Compatible with PC-DOS.
- Compatible with all 32 bit compiler such as Lahey LF90 and F77, Microsoft FORTRAN, Compaq Visual
FORTRAN as well as Salford both FORTRAN 77 and 90.
