ABSTRACT:
A character pattern generating apparatus for generating a bit map data from outline data corresponding to a pattern having a curve portion comprises: a discriminating circuit to discriminate a size of pattern data to be output; and a deciding circuit to decide whether the bit map data is generated or not by regarding the curve portion as a straight line from the outline data on the basis of the discrimination of the discriminating circuit. The curve portion is a portion to form a Bezier curve on the basis of the outline data.
