Hi,

As of DX 6.1, DirectDraw provides no means of blending two images/surfaces
in any way (other then simple color keying), though I belive, such
capablities are included in DX 7.0 (I may be mistaken.)

If you want to have DX <= 6.1 blend images, you have to use Direct3D: Setup
one or both images as textures, and then blend away!

Hope this helps,
David
