CHAP User's Manual.

Abstract

A computer representation for line drawings that has been found particularly convenient and has become widely accepted is the chain code. This representation is compact and allows most common processing functions to be performed efficiently. CHAP is a collection of FORTRAN routines designed to process chain-encoded line drawings. Routines exist in CHAP to manipulate, synthesize, analyze, and do input and output upon chains. This report is intended to serve as a user's manual for CHAP. It describes the use of the CHAP routines along with other information needed to write a program utilizing the routines. A programming example is included. (Author)
