ABSTRACT:
A method for adjusting a grayscale spline, defined by a set of interconnected points, for an output device including the steps of adjusting a location of a first point previously located on the grayscale spline, adjusting a location of at least one other point, previously located on the grayscale spline, based on the adjusted location of the first point, generating a grayscale spline through the first point and the at least one other point, and producing an image with the output device using the generated grayscale spline. In addition, an apparatus for adjusting a grayscale spline, defined by a set of interconnected points, for an output device including an apparatus for adjusting a location of a first point on the grayscale spline, an apparatus for automatically adjusting a location of at least one other point, previously located on the grayscale spline, based on the adjusted location of the first point, and an apparatus for generating a grayscale spline through the first point and the at least one other point.
