I''m trying to blend two bitmaps (on 16-bit ddraw7 surfaces) at runtime to create a stock fade effect between two screens. Can someone tell me how to achieve this, or direct me to a tutorial? Thanks!

I think it can be done with alpha-blending.... I don''t know if additive-blending or other types can do the trick, but I would use alpha-blending... Gamedev.net has good tutorials about this, but if anyone has a better idea, plz post, because alpha-blending is slow(in most cases) and it is not the best thing to code.
Search Articles & Resources for Alpha Blending.

Alright. What values do I need to change in a general alpha blending algorithm to decrease/increase the level of translucency?
