Image processing method and apparatus |
摘要 |
In an image processing method and apparatus, contour vector data are extracted in order to generate an excellent image without increasing the width of a line even after magnification-varying processing. When extracting a vector present along a binary-image edge changing from a black pixel to a white pixel, a vector present along a border which is provided between the black pixel and the white pixel and closer to the black pixel is extracted. <IMAGE> |
