Converting pSDL_COLOR to TColor/Cardinal and back

[Super Vegeta]

If by Cardinal, you mean a color in $RRGGBB format, then just (*, +) or (shl, or) the components of sdl's color.

Function SDL_ColorToUInt(Col:PSDL_Color):Longword;
   begin Exit((Col^.R shl 16) or (Col^.G shl 8) or (Col^.B)) end; 

Function Make_PSDL_Color(Num:LongWord):PSDL_Color;
   Var Col:PSDL_Color;
   begin New(Col);
   Col^.R:=Num shr 16;
   Col^.G:=Num shr 8;
   Col^.B:=Num;
   Exit(Col)
   end;
