Determines the emphasis given to edges and flat areas in color and grayscale images. Images requiring precise edge definition will benefit from a lower setting. If precise edges are not as important as consistency in flat color areas, increase this setting. The practical range of values is 0.1 to 10 where 0.1 represents maximum edge definition with less emphasis on flat areas, and 10 represents minimum edge definition with smoother areas of relatively consistent color.
Acceptable values: 0.0 - 10.0
Default: 2
