从内存中载入图片的例程

shenguhan

这是给那些不知道的朋友看的，
知道了的就不要看了，
看之前建议先看看关于打包方面的资料！

下面这段程序演示了如何内存中加载图片资源，当然，之前你必须先将图片解压到内存中！（此程序部分参照了kylinx写的gppGameLib2.3）

void LoadBmp(LPDIRECTDRAWSURFACE7 surface,LPBYTE FileBuffer,DWORD FileLen,int bwidth,int bheight)
{
LPVOID pvData=NULL;
HGLOBAL hGlobal = GlobalAlloc(GMEM_MOVEABLE, FileLen);
pvData=GlobalLock(hGlobal);
memcpy(pvData,FileBuffer,FileLen);
GlobalUnlock(hGlobal);

LPSTREAM pStream = NULL;
LPPICTURE gpPicture=NULL;
CreateStreamOnHGlobal(hGlobal,true,&pStream);
OleLoadPicture(pStream,FileLen, false, IID_IPicture, (void**)&gpPicture);

long lWidth,lHeight;
gpPicture->get_Width(&lWidth);
gpPicture->get_Height(&lHeight);
HDC hdc;
surface->GetDC(&hdc);
RECT rect={0,0,bwidth,bheight};
gpPicture->Render(hdc,0,0,bwidth,bheight,0,lHeight,lWidth,-lHeight,&rect);
surface->ReleaseDC(hdc);
GlobalFree(hGlobal);
pStream->Release();
}

另外，如果谁有更好的方法麻烦告诉我啊！

sdk中
hBitmap = LoadBitmap (hInstance, TEXT ("Bricks")) ;
hdc = GetDC(hwnd) ;
hdcMem = CreateCompatibleDC (hdc) ;
SelectObject (hdcMem, hBitmap) ;

BitBlt (hdc, 0, 0, cxClient,cyClient, hdcMem, cxSource, cySource, SRCCOPY) ;


DeleteObject(hBitmap);
DeleteDC (hdcMem) ;
ReleseDC (hdc);


哈哈搞定
