Color.ScA Property

Definition

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

public:
 property float ScA { float get(); void set(float value); };
public float ScA { get; set; }
member this.ScA : single with get, set
Public Property ScA As Single

Property Value

The ScRGB alpha channel value of the Color structure, a value between 0 and 1.

Remarks

The alpha channel of a Color structure determines the amount of transparency the Color has. An alpha value of 1 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.
