DeHalo_alpha (clip clp, float "rx", float "ry", float "darkstr", float "brightstr", float "lowsens", float "highsens", float "ss") 


        clip  clp =

            Input clip. 


        float  rx = 2.0
        float  ry = 2.0

            As usual, the radii for halo removal. 
            Note: This function is rather sensitive to the radius settings. Set it as low as possible! If radius is set too high, it will start missing small spots.

            Range: 1.0 to 3.0 


        float  darkstr = 1.0
        float  brightstr = 1.0

            The strength factors for processing dark and bright halos. Default 1.0 both for symmetrical processing. 
            On Comics/Anime, darkstr=0.4~0.8 sometimes might be better ... sometimes. In general, the function seems to preserve dark lines rather well.

            Range: 0.0 to 1.0 [<0.0 and >1.0 possible] 


        int  lowsens = 50
        int  highsens = 50

            Sensitivity settings, not that easy to describe them exactly ... 
            In a sense, they define a window between how weak an achieved effect has to be to get fully accepted, and how strong an achieved effect has to be to get fully discarded. 
            Defaults are 50 and 50 ... try and see for yourself. 

            Range: 0 to 100 


        float  ss = 1.5

            Supersampling factor, to avoid creation of aliasing. ss=1.0 -> no supersampling. 

            Range: 1.0 to ???
