Property Value

The ScRGB alpha component value of this Color structure.

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 components (A, R, G, B) and the ScRGB components (ScA, ScR, ScG, ScB) of the Color structure are synchronized properties. For example, when R, the sRGB red component, is modified the ScRGB red component, ScR, is transformed to the equivalent value.
