Abstract
Line patterning apparatus for use with a vector generator comprises a memory storing a plurality of addressable line pattern bit strings. Each string comprises a series of ones and zeros defining a predetermined pattern of dots and/or dashes. Associated with each pattern string is a pattern restart string defining the length of the pattern. The bits of an addressed pattern string and the associated pattern restart string are serially provided by the memory in response to an addressing counter. The bits of the pattern string are utilized for video inhibition to superimpose the pattern on a vector being generated. The bits of the pattern restart string are utilized to clear the counter when a preset restart bit is encountered in the string by the counter.
