SDL函数说明

• SDL_SetVideoMode
  设置图像模式
  SDL_Surface *SDL_SetVideoMode(int width, int height, int bpp, Uint32 flags)
          Set up a video mode with the specified width, height and bits-per-pixel.
  Return Value
           The framebuffer surface, or NULL if it fails. The surface returned is freed by SDL_Quit() and should nt be freed by the caller.
• SDL_WM_SetCaption
  void SDL_WM_SetCaption(const char *title, const char *icon)
      Sets the title-bar and icon name of the display window.
• IMG_Load函数

         SDL_Surface *IMG_load( char *filename)

         功能：加载图象文件

         它是扩展库中的一个导入图象的函数，支持的图象格式有BMP, PNM, XPM, LBM, PCX, GIF, JPEG, TGA 和PNG。

• SDL_DisplayFormat函数

         SDL_Surface *SDL_DisplayFormat(SDL_Surface *image)

         功能：建立最佳图象

         它会将图象的格式转换为同屏幕相同的格式。这样，如果出现32bit、24bit的图片，都将统一格式显示。但会降低速度。

• SDL_BlitSurface

         显示图像
         SDL_BlitSurface(SDL_Surface *source, NULL,  SDL_Surface* destination,  SDL_Rect *offset )
         其中SDL_Rect是矩形坐标。它将source图象按照Offset规定的坐标贴在destination屏幕上。

• SDL_Flip

          更新屏幕

• SDL_FreeSurface

          释放图象
