Color.A Property


Gets or sets the sRGB alpha channel value of the color.

Namespace:   System.Windows.Media
Assembly:  PresentationCore (in PresentationCore.dll)

Public Property A As Byte

Property Value

Type: System.Byte

The sRGB alpha channel value of the color, a value between 0 and 255.

The alpha channel of a Color structure determines the amount of transparency the Color has. An alpha value of 255 indicates the Color is completely opaque and a value of 0 indicates the color is completely transparent.

The sRGB channels (A, R, G, B) and the ScRGB channels (ScA, ScR, ScG, ScB) of the Color structure are synchronized properties. For example, when A, the sRGB alpha channel, is modified, the ScRGB alpha channel, ScA, is converted to the equivalent value using the 0-1 range that the Sc scheme supports.
