ABSTRACT:
In a run-length represented image an image area with reverse print is recognized. Two borders (left and right) are determined and in a plurality of steps the run transitions are removed, first on the left border of the area and then at the right border of the area, causing all runs within the area of reverse print to take on the reverse color.
