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

JScript

	float a,
	float r,
	float g,
	float b
)

You cannot use methods in XAML.

Parameters

a: Type: System.Single
The ScRGB alpha channel, ScA, of the new color.

r: Type: System.Single
The ScRGB red channel, ScR, of the new color.

g: Type: System.Single
The ScRGB green channel, ScG, of the new color.

b: Type: System.Single
The ScRGB blue channel, ScB, of the new color.

Return Value

Type: System.Windows.Media.Color
A Color structure with the specified values.

Remarks

The alpha channel of a color determines the amount of transparency of the color. An alpha value of 1 indicates that the color is completely opaque, and a value of 0 indicates that 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 R, the sRGB red channel, is modified the ScRGB red channel, ScR, is transformed to the equivalent value.

Examples

The following example shows how to use the FromScRgb method to create a Color structure.

Copy

private Color FromScRgbExample()
{
    // Create a blue color using the FromScRgb static method.
    Color myScRgbColor = new Color();
    myScRgbColor = Color.FromScRgb(1, 0, 0, 1);
    return myScRgbColor;
}
