Hello All!

I create a PSDL_Surface like this:
Code:
FSurface := SDL_CreateRGBSurfaceFrom(@FPixels[0], FWidth, FHeight, 32, FWidth*SizeOf(FPixels[0]), rmask, gmask, bmask, amask);
Where FPixels is a dynamic array of Uint32. Now when I try to make a certain color transparent nothing happens. Anybody have any idea to why? Maybe even have some tutorial on how to do this sort of thing (I haven't found any myself).

Any help is really appreciated!
