1. NAME AND TITLE
EZVIDEO: Graphics Routines for the IBM PC
Oak Ridge National Laboratory
3. CODING LANGUAGE AND COMPUTER
Fortran 77; IBM PC or Compatible.
4. NATURE OF PROBLEM SOLVED
EZVIDEO simulates a subset of the DISSPLA plotting package to make plots on the IBM PC
screen. Screen dumps can also be made to an attached LaserJet or Epson printer to make hard copy
without using terminal emulators. The forerunner of EZVIDEO was called EZPLOT.
5. METHOD OF SOLUTION
The subroutines in the EZVIDEO system are based on the Hewlett Packard HP 9000 simulation
of DISSPLA. These routines manipulate the pen movements on the screen and are also capable of
capturing these same movements so that a hardcopy can be made to a dot matrix or laser printer.
6. RESTRICTIONS OR LIMITATIONS
For plotting on the IBM PC, the plotting emulator PCPLOT is needed.
7. TYPICAL RUNNING TIME
The sample problem runs in about 2 minutes on the IBM PC/XT.
8. COMPUTER HARDWARE REQUIREMENTS
EZVIDEO is operable on an IBM PC with at least 105 K of memory.
9. COMPUTER SOFTWARE REQUIREMENTS
Microsoft Fortran Version 3.31 or higher is required for compilation.
The code was run at RSIC under PC DOS 3.1. PCPLOT and TEK terminal emulators are required
for full implementation.
