PURPOSE:To obtain outline character data by a relatively simple method by noticing the states of four nearby dots around a coordinate point on the boundary part of dots and determining the value of this coordinate point as a dot value code. CONSTITUTION:In the processing which reads the value of the form of a dot pattern discriminated for character pattern data 11 as a dot value code, coordinate points of boundary parts of respective dots are scanned and are successively converted to dot value codes to obtain dot value code data 2 for character pattern data 11. Thereafter, read dot value code data 12 is used to move the coordinate point of the noticed boundary part based on the outline tracing direction preliminarily determined in an encoded table by the outline tracing direction and the tracing operation preliminarily determined in this table, thereby extracting outline data of the pertinent character pattern. Thus, the direction of the next coordinate point for outline extraction is relatively easily obtained by one scanning, and even data of one-dot line width is extracted as the outline. |
