ABSTRACT:
A character processing apparatus which has character data as a coordinate point array on contour lines and converts the character data into dot information and outputs. This apparatus includes: a discriminating circuit to discriminate whether two continuous points in the coordinate point array constitute horizontal or vertical line elements on the basis of the coordinate values between the two points; and an arithmetic operating device which, when it is determined that those two points constitute a horizontal or vertical line, enlarges or reduces a thickness of this horizontal or vertical line so that the relation of thickness of the horizontal and vertical lines is equal to the relation of thickness in the character data. The discriminating circuit performs the discrimination before the character data is converted into the dot information. The arithmetic operations are independently performed in accordance with a designated size with respect to the coordinate points indicative of a main outer shape of a character and to the coordinate points representative of an additional outer shape. With this apparatus, the horizontal and vertical lines can be output with a high quality with various sizes.
