D3DXLoadSurfaceFromSurface

I am currently rewriting my slow old 2D engine to be a little more efficient. In the old version it copied a bitmap pixel by pixel to the desired surface frame by frame, which was, of course, extraordinarily slow. Now I copy it once, to a stored surface which I then D3DXLoadSurfaceFromSurface to the desired surface. The only problem with this is that with my old version if the current pixel (the one it''s about to copy) matched the ColorKey, it was never copied and with D3DXLoadSurfaceFromSurface it copies black instead, forcing a black rectangle around all my 2D bitmaps I''m trying to display. Is there a way, to simply make D3DXLoadSurfaceFromSurface not touch instead of setting all the ColorKey-colored pixels to black?

I''m glad you got it to work!
Sorry that i side-tracked from the original blitting idea, i have to admit that i didn''t read your code very carefully at first...
The quad rendering is the "right" way in this case.

kind rgds,
