摘要

A system for computerizing changes to engineering drawings by separating graphical and textual information in a digital representation of a drawing so that desired changes can be made to the digital representation. Separation is accomplished by scanning the document and analyzing it element by element until all objects have been separated one from another. Special purpose circuitry is provided to test for connectivity between one state bits in a single row and adjacent one state bits in the directly neighboring row.
