A digital straight line is represented by a chain code of directions which satisfy Freeman's three criteria. Given two chain codes of digital straight lines and their starting pixels where their equations are not known, the paper will describe how to determine if they are parallel, overlapped, or intersected. An algorithm with only integer arithmetic is also implemented to find the intersection.
