ABSTRACT:
An image processing apparatus for correcting shape errors when a graphic image to which contour line data was given is painted and developed comprises: an input device to input contour line data of image information; a circuit to make a contour line pattern of the image information on the basis of the contour line data; a circuit to make a painted pattern in which the inside of the contour line pattern was painted; a circuit to narrow the painted pattern; and a contour line correcting circuit to obtain the exclusive-OR combination of the narrowed painted pattern and the contour line pattern. The contour line pattern is eliminated from the painted pattern by the narrowing circuit. The contour line correcting circuit has a converter to convert the contour line pattern in correspondence to the drawing direction of the contour line pattern and obtains the exclusive-OR combination of the converted contour line pattern and the painted pattern. This apparatus can prevent a small blank region in an image being painted over and can effect a feature of a contour line.
