Fade Transform

Fades from one DXSurface object to another or from one DXSurface to black, depending on the number of inputs passed. If you use two inputs, the first input gradually fades into the second input as the value of the Progress property from IDXEffect goes from 0 to 1. If you use only one input, the input gradually fades to black as Progress goes from 0 to 1.

The Overlap and Center custom properties are relevant only if you are using two inputs.

Note To use this transform, you need to have Microsoft® DirectX® Media 6, Microsoft Internet Explorer 5, Microsoft Windows® 98 Second Edition, or Windows 2000 installed.
