Assembly: Microsoft.WindowsMobile.DirectX (in Microsoft.WindowsMobile.DirectX.dll)

Syntax

'Declaration
Public Property AlphaTestEnable As Boolean
    Get
    Set
'Usage
Dim instance As RenderStateManager
Dim value As Boolean

value = instance.AlphaTestEnable

instance.AlphaTestEnable = value

public bool AlphaTestEnable { get; set; }

public:
property bool AlphaTestEnable {
    bool get ();
    void set (bool value);
}

member AlphaTestEnable : bool with get, set

Property Value

Type: System.Boolean
true if per-pixel alpha blending is enabled; otherwise, false. The default value is false.

Remarks

If the test passes, the pixel is processed by the frame buffer. Otherwise, all frame-buffer processing is skipped for the pixel. The test is done by comparing the incoming alpha value with the reference alpha value, using the comparison function provided by AlphaFunction. The reference alpha value is determined by the value set for ReferenceAlpha.
