Convert Surface


參考資訊:
1. libctru doc
2. 3ds-examples

說明:

API
SDL_Surface* SDL_ConvertSurface(SDL_Surface *src, const SDL_PixelFormat *fmt, Uint32 flags)

main.c

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

    SDL_Init(SDL_INIT_VIDEO);
    screen = SDL_SetVideoMode(400, 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

完成
