    DirectX eqivalent

    Right now I am using the atlimage header file with transparentblt. I was wondering what the DirectX equivalent was. Any help would be great.

    When you create your direct draw surface you must specify a source or destination color key in one of the DDSURFACEDESC2 members. Then when you use IDirectDrawSurface::Blt( ) , use the appropriate flag for the source/dest color key information. For the exact flags and members look it up in your DX Help File.
