IMAGE PROCESSING APPARATUS AND METHOD FOR PRODUCING PIXEL DATA IN DEPENDENCE UPON THE SHAPE OF A SECTIONAL LINE EXTENDING BETWEEN BOUNDARY LINES OF AN OBJECT

An image processing apparatus for generating visible output images, including visually distinct images. A processor generates displayable image data by writing data to a frame store which is repeatedly read therefrom. An input, preferably in the form of a mouse, supplies operator defined input signals to the processor for defining boundary lines (B1, B2) of an object and a sectional line (51), which identifies two boundary lines as defining the object. In addition, a data store is provided for storing data generated in response to the input signals and for storing attribute data defining visual attributes of the objects.
