Description: Pass the file path to the function :) | If you have SDL_Image stuff to load other file types, replace SDL_LoadBMP with IMG_Load and #include <SDL/SDL_image.h> (example shown in the code)A function to load and optimise an image.

#include <SDL/SDL.h>

/* Function to load and return an optimised image
 * using the SDL graphics libraries
 * author: Danny Battison

 */

SDL_Surface *Load_Optimal (char *filename)
{
    SDL_Surface *loaded  = NULL; /* The surface to load the basic image */
    SDL_Surface *optimal = NULL; /* The optimised surface */
    loaded = SDL_LoadBMP (filename); /* Load the basic image */
    if (loaded != NULL) /* This is why NULL is important, now we can check if it was loaded successfully */
    {
        optimal = SDL_DisplayFormat (loaded); /* Load an optimised version of the basic surface */
        SDL_FreeSurface (loaded); /* Delete the basic one, it's no longer needed */
    }
    return optimal; /* Return the optimised image */
