Color.FromAValues Method

Creates a Color structure using the specified alpha component, color channel values, and color profile.

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

public static Color FromAValues (
	float a,
	float[] values,
	Uri profileUri
)
public static Color FromAValues (
	float a, 
	float[] values, 
	Uri profileUri
)
public static function FromAValues (
	a : float, 
	values : float[], 
	profileUri : Uri
) : Color
You cannot use methods in XAML.

Parameters

a

The alpha channel of the new Color structure.

values

The collection of values used to specify the color channels of the Color structure. These values map to the profileUri.

profileUri

The International Color Consortium (ICC) or Image Color Management (ICM) color profile used for the Color structure.

Return Value

The Color structure created.

A International Color Consortium (ICC) or Image Color Management (ICM) color profile contains a color system profile for a particular application or device such as a color printer. This profile is matched to a common profile that in turn can be mapped to the individual profiles of other devices. This allows the color system used by one computer device to match the colors from other applications and devices on the same or other computer systems.

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

private Color FromAValuesExample()
{
    // Create a brown color using the FromAValues static method.
    Color myAValuesColor = new Color();
    float [] colorValues = new float[4];
    colorValues[0] = 0.0f;
    colorValues[1] = 0.5f;
    colorValues[2] = 0.5f;
    colorValues[3] = 0.5f;

    // Uri to sample color profile. This color profile is used to 
    // determine what the colors the colorValues map to.
    Uri iccUri = new Uri("C:\\sampleColorProfile.icc");

    // The FromAValues method requires an explicit value for alpha
    // (first parameter). The values given by the second parameter are
    // used with the color profile specified by the third parameter to 
    // determine the color.
    myAValuesColor = Color.FromAValues(1.0f, colorValues, iccUri);
    return myAValuesColor;
}
