SDL_DisplayFormat(3)						 SDL API Reference					      SDL_DisplayFormat(3)

NAME
       SDL_DisplayFormat - Convert a surface to the display format

SYNOPSIS
       #include "SDL.h"

       SDL_Surface *SDL_DisplayFormat(SDL_Surface *surface);

DESCRIPTION
       This  function  takes  a  surface and copies it to a new surface of the pixel format and colors of the video framebuffer, suitable for fast
       blitting onto the display 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.

RETURN VALUE
       If the conversion fails or runs out of memory, it returns NULL
