Abstract

PURPOSE:To automatically and always uniformly correct jag by detecting a jaggy part, whose correction is necessary, from source data and generating correction data, where dots are arranged in right-angles isosceles triangles, to fill the jaggy part of expanded data. CONSTITUTION:An expanding means 1 which expands source data S stored in a bit map in longitudinal and transverse directions in accordance with a magnifying power, a jag detecting means 2 which detects a jaggy pattern to be corrected from expanded source data, a correction data generating means 3 which performs operation in accordance with the jaggy pattern and the magnifying power to a generate correction data where dots are arranged in a right- angled isosceles triangles, and a synthesizing means 4 which synthesizes correction data with the corresponding jaggy part of expanded source data are provided. Thus, since jag on the expanded pattern is automatically corrected when source data and its magnifying power are only designated, uniform and accurate jag correction is performed in a short time, and especially, a less rugged and smooth expanded pattern is obtained in case of expansion of an oblique line or the like.
