  • Patent number: 4958272
    Abstract: An apparatus and system for generating smooth shaded continuous tone images based on user selected curve constraints that define the color intensity level transition in the image. The curve constraints define an intensity surface for each selected color. These surfaces are mapped, pixel by pixel onto a two-dimensional matrix array. The image generated from this two-dimensional matrix array can be stored, modified transmitted, displayed, or printed.
