#include "SDL.h" SDL_Surface *SDL_DisplayFormat(SDL_Surface *surface);

It calls SDL_ConvertSurface If you want to take advantage of hardware colorkey or alpha blit acceleration, you should set the colorkey and alpha value before calling this function. If you want an alpha channel, see SDL_DisplayFormatAlpha.
