Convert Surface

參考資訊：
1. docs

main.c

#include <stdio.h>
#include <stdlib.h>
#include <SDL.h>
 
int main(int argc, char **argv)
{
    SDL_Surface *screen = NULL;

    SDL_Init(SDL_INIT_VIDEO);
    screen = SDL_SetVideoMode(320, 240, 16, SDL_HWSURFACE);

    SDL_Surface *bmp = SDL_LoadBMP("main.bmp");
    SDL_Surface *t = SDL_ConvertSurface(bmp, screen->format, 0);
    SDL_SoftStretch(t, NULL, screen, NULL);
    SDL_FreeSurface(t);
    SDL_Flip(screen);
    SDL_Delay(3000);

    SDL_FreeSurface(bmp);
    SDL_Quit();
    return 0;
}

P.S. 用來轉換Pixels像素格式，如：main.bmp是32Bits，則可以轉換成16Bits，方便處理

編譯、執行

$ gcc main.c -o main -lSDL -I/usr/include/SDL
$ ./main
