Exceptions

Exception	Condition
ArgumentException	The scale was less than 0.

Remarks

Each edge magnitude image pixel value is set equal to the Sobel-computed grey value difference at the corresponding location multiplied by this scaling factor.

A value of 0.89 guarantees no pixel value exceeds 255, the maximum grey value. Magnitude values greater than 255 are clipped. The valid range is 0.5 through 50.

Default Value: 1.0
