1. NAME AND TITLE

EZVIDEO: Graphics Routines for the IBM PC

2. CONTRIBUTOR

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.
