I don''t know anything about using the alpha channel. But I would really like to use it. Because I don''t have the full DX7 SDK(will do in the next 8 days with getright) - just the header files I don''t have any documentation about it. If anyone has any tutorial URLs or a simple program with a bitmap and an alpha channel surface please could you send it to me....thanx //--- Created by Tom Oram --- // tom.oram@vodafone.net

are planning to use ddraw () or D3D? and what bit depth?

Ddraw 16bit color

To bad the alpha channel doesn''t with DDraw then.

Microsoft haven''t implemented support for blitting with alpha yet. But you can still do your own blit function that uses alpha and DirectDraw surfaces as the surfaces do support the alpha channel. Hopefully DX8 will have support for alpha in blitting.

Check this out: http://www.gamedev.net/reference/programming/features/mmxblend/

(Why the hell does Microsoft not include this stupid Alpha blending??? )

Because it''s fun to sit for hours trying to optimize your alpha blending assembly routines...
