Color.FromScRgb Method

Creates a new Color structure by using the specified ScRGB alpha channel and color channel values.

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

public static Color FromScRgb(
	float a,
	float r,
	float g,
	float b
)

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.

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.

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


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;
}
