    • 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.
    • 用于图案处理的装置包括用于控制CRT,键盘,CPU,RAM等的显示的显示控制单元,所述CPU适于控制所述装置并且包括分段信息提取单元和边界信息提取单元, 位置信息设定单元,其中所述段信息提取单元基于至少两组坐标,从构成轮廓的多个段提取与坐标系的x轴和y轴平行的区段 指示每个段的位置,而边界位置信息设置单元基于指示与坐标的x轴平行的段的位置的各组坐标来确定轮廓的水平边界位置 并且基于指示段的平行位置的各组坐标来确定轮廓的垂直边界位置 坐标系的y轴。
