Abstract
An apparatus for pattern processing includes a display control unit for controlling display by a CRT, a keyboard, a CPU, a RAM, and the like, the CPU being adapted to control the apparatus and incorporating a segment-information extracting unit and a boundary-position-information setting unit, wherein the segment-information extracting unit extracts segments respectively parallel with an x-axis and a y-axis of the coordinate system from a plurality of segments constituting the outline, on the basis of at least two sets of coordinates indicating a position of each of the segments, while the boundary-position-information setting unit determines a horizontal boundary position of the outline on the basis of the respective sets of coordinates indicating the position of the segment parallel with the x-axis of the coordinate system, and determines a vertical boundary position of the outline on the basis of the respective sets of coordinates indicating the position of the segment parallel with the y-axis of the coordinate system.
