A method of eliminating unwanted steps at edges in image or graphic representations in the line raster, in particular in on-line operation having the steps:

• a) Application of an edge operator to an image portion for coarsely ascertaining at least one rastered edge configuration,
• b) Determining the position of at least a first pixel from the amount of those pixels which form the rastered edge configuration or adjoin said rastered edge configuration,
• c) Approximation of a straight line for ascertaining a probable configuration of the unrastered image edge in the proximity of the first pixel,
• d) Ascertaining a criterion from the approximation straight line and the position of the first pixel for mixing a color X to the color C in the first pixel considered, and
• e) Mixing the ascertained color X to the color C in the first pixel considered.
