The IDxtAlphaSetter interface sets properties on the Alpha Setter effect.
This interface is used internally by DirectShow Editing Services (DES) when it renders the Alpha Setter effect. DES applications do not have to use this interface. To set the properties on a transition in DES, use the IPropertySetter interface.
In addition to the methods inherited from IDXEffect, the IDxtAlphaSetter interface exposes the following methods.
| Method | Description |
| get_Alpha | Retrieves the alpha value for the entire image. |
| get_AlphaRamp | Retrieves the alpha ramp property. |
| put_Alpha | Specifies the alpha value for the entire image. |
| put_AlphaRamp | Specifies the alpha ramp property. |
