    Alpha blending (i.e. true blending) is not supported in DirectDraw.  If you would like that you either need to roll your own blitters on top of DirectDraw, use GDI+ or move to using Direct3D (and using D3DX Sprites).

    You want to use alpha-blending instead of color-key with DDraw Can you use the D3DX sprite library

    thx, for now we'll try to prepare graphics will one transparent key, then if we'll get free time, will try to recode engine to d3d sprites
