The degree of opacity. The valid range of values is from 0 through 1. A value of 0 indicates that the shadow is completely transparent, and a value of 1 indicates that the shadow is completely opaque. A value of 0.5 indicates the shadow is 50 percent opaque, a value of 0.725 indicates the shadow is 72.5 percent opaque, and so on. Values less than 0 are treated as 0, while values greater than 1 are treated as 1. The default is 1.
Remarks
This property must be used to set the opacity of the DropShadowBitmapEffect because the alpha level component of the DropShadowBitmapEffect.Color property is ignored.
The following illustration demonstrates the effect of this property.
