Data processing method of binary graphic pattern and system therefor

摘要

Data on the characteristic point on the contours of unit patterns such as characters, marks, patterns and/or the like are stored in a memory. The data are then read out as needed and then subjected to magnification-changing processing such as enlargement or reduction, rotation processing and/or the like. The resulting unit pattern data are then arranged in accordance with a given layout so as to establish desired positional relationship among the unit patterns. The thus-arranged pattern data are then converted into one-dimensional time series data so as to ON-OFF control the scanning and exposing means of a one-dimensional output unit. The above method permits to process a pattern in a single step. The specification also discloses a system useful in the practice of the above method.
