ABSTRACT:
This invention provides an image processing method and apparatus. According to this invention, contour line data when viewed from a the main scan direction are generated on the basis of the connection relationship between a target line element and adjacent line elements before and after the target line element in one direction of continuous line elements, and a direction of an area to be painted out. It is then set that a pixel position of an odd-numbered contour encountered in a scan operation in the main scan direction indicates a forward rotation position of the area, and that an adjacent pixel position in the main scan direction of an even-numbered contour encountered in the scan operation indicates a reverse rotation position of the area. Thereafter, it is discriminated that a portion between an odd-numbered contour position, when viewed from a scan direction on each scan line, to a pixel position immediately before an even-numbered contour position is a portion inside the area of a closed figure, and remaining portions are outside the area of the closed figure.
