AlphaBlendBackColor Property

Visual Basic
C#

'Declaration
 
Public Overridable Property AlphaBlendBackColor As Integer

'Usage
 
Dim instance As PSObject
Dim value As Integer
 
instance.AlphaBlendBackColor = value
 
value = instance.AlphaBlendBackColor

public virtual int AlphaBlendBackColor {get; set;}

Property Value

Integer representing the amount of alpha blending

Alpha blending determines the amount of transparency of the background color.

This example shows the use of the property in customizing a shape to illustrate the use of the property for classes that inherit this property.
