IMAGE PROCESSING METHOD, IMAGE PROCESSOR, IMAGE PROCESSING PROGRAM AND RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To automatically prepare a cut curve for trimming processing even when, for example, the crossline part of two faces is a line group constituted of a plurality of segments or curved segments. SOLUTION: A series of processing constituted of first processing to judge whether or not the crossline part is a line group constituted of a plurality of segments or curved segments or a single segment or curved segment and second processing to extend at least either the segments or curved segments of adjacent segments or curved segments, and to link the adjacent segments or curved segments when the crossline part is the line group is repeated until the judged result of the first processing is turned to be a single segment or curved segment so that the crossline part can be obtained as one segment or curved segment.
