Hi there i have a such question. Im trying to blit with color key. when my texture has a white as transparent and im setting colorkey as white it''s ok // ddck.dwColorSpaceHighValue=RGB(255,255,255); // and low... but with any other color its wrong e. g. grey // ddck.dwColorSpaceHighValue=RGB(125,125,125); // and low... are there other functions or macros to make a proper onemy texture is A8R8G8B8 style.

using the RGB macro is a massive nono, it returns a colorref. You need to set up your own macro.

Please state the nature of the debugging emergency.

Well, I dont know about D3D programming but there is a DDColorMatch function that, if you have a surface, returns the color index of a certain rgb value.

So if the color key does not change (i.e. it is set to a certain color space at the beginning and then stays), use DDColorMatch and assign its return value to your color key.

DDColorMatch is defined in ddutil.cpp anywhere in the mssdk/samples directory.
