Have you also tried to use the GDI AlphaBlend function? This is the one which should be used I think and we back it by XRender .. Roderick
Sorry for the OT : apropos AlphaBlend and RGBA bitmaps... what happens with BitBlt on a destination DIB which has alpha channel ? it gets overwritten or the dest alpha channel is simply ignored ? I mean BitBlt(dstBmp......., SRC_COPY) what happens to dstBmp alpha ? and BitBlt(dstBmp......., SRC_AND) ??? Max
