我装载一张图片，运行都通的过，但是就是没有画面，我想了一下可能是因为图片是376，222的，于是我更改程序为376，222的，但是依旧没有图像，这是怎么回事啊

int Game_Init(void *parms)
{
// this function is where you do all the initialization 
// for your game
	DDraw_Init(SCREEN_WIDTH, SCREEN_HEIGHT, SCREEN_BPP);
	Load_Bitmap_File(&bitmap16bit,"beginmenu.bmp");
	
	Create_Bitmap(&startmenu,0,0,376,222,16);
	Load_Image_Bitmap(&startmenu,&bitmap16bit,0,0,BITMAP_EXTRACT_MODE_ABS);
	
	
	
	Unload_Bitmap_File(&bitmap16bit);

// start up DirectDraw (replace the parms as you desire)



return(1);

} // end Game_Init

///////////////////////////////////////////////////////////

int Game_Shutdown(void *parms)
{

return(1);
} // end Game_Shutdown

///////////////////////////////////////////////////////////



//////////////////////////////////////////////////////////

int Game_Main(void *parms)
{
// this is the workhorse of your game it will be called
// continuously in real-time this is like main() in C
// all the calls for you game go here!

Start_Clock();
DDraw_Fill_Surface(lpddsback, 0);
DDraw_Lock_Back_Surface();
Draw_Bitmap16(&startmenu, back_buffer, back_lpitch, 0);
DDraw_Unlock_Back_Surface();
DDraw_Flip();
// check of user is trying to exit
if (KEY_DOWN(VK_ESCAPE))
	PostMessage(main_window_handle, WM_DESTROY,0,0);

// sync to 30ish fps
Wait_Clock(30);

// return success
return(1);

} // end Game_Main

检查你的图片色深

// load in the generator bob image
Load_Bitmap_File(&bitmap8bit, "GENS4.BMP");

注意这个函数是8位色深

[hankcs]

在你的代码里面

Load_Bitmap_File(&bitmap16bit,"beginmenu.bmp");

色深是16，所以要找个16位的图片
