ABSTRACT:
A pattern processing system which comprises a main memory (3) and an outline data extractor (4) and a stroke setter (5). The outline data extractor (4) extracts a plurality of pairs of opposing segments on an outline of a pattern, obtain a position of a segment in one side of the segments in each pair, and also obtains a width between the segments in each pair on the basis of outline font data stored in the main memory (3). The stroke setter (5), when the obtained widths between the segments in the pairs are equal to each other, calculates an average distance between the segments on the basis of the positions of segments in one side in the pairs, selects one of the positions of the segments in one side and using a selected position as a reference position, corrects the remaining positions of the segments in one side other than the selected position on the basis of the average distance and the reference position and obtaining respective correction positions therefor, and adds the width to the reference position of the segments in one side and the correction positions to thereby obtain correction positions of the segments in another side in the pairs of segments.
