---|---|---|
Edge lightening threshold |
Defines the threshold for edge detection. If set to 0 (default), all edges will be detected. |
|
Edge brightness upscaling multiplier |
Defines the level of brightness in which edges are drawn |
|
Non-edge downscaling multiplier |

For sources with large contiguous areas like a sky or a wall the Edge lightening threshold can be used to ignore the small and subtle changes in color or luminance that would otherwise be detected as edges.
