Displaying and improving run-length encoded images on a BTOS system

The goal of this project was decode and display a run-length encoded image, and to apply error concealment techniques to the decoded image. The software was written in the C programming language, a language learned during the course of this project. This software was written to read a run-length encoded ASCII file and translate it to a bit-mapped ASCII file. The software can display the bit-mapped image on a video screen and print it on a laser printer.

The software also implements four error concealment techniques and displays the improved image on the video screen and on a laser printer.

This software was written for the U.S. Coast Guard's Standard Workstation, running the Unisys Corporation's Burroughs Technology Operating System (BTOS), using the BTOS C compiler. Most of the code should be transportable to other operating systems, but the display functions make use of system library functions, which may not be available on other operating systems.
