?於D3DXSaveSurfaceToFile的memory leak

akira32

我想??ack buffer的?面?Υ娉梢??png的?D?n,不?加了以下的程式?後,?束程式??霈F"The D3D device has a non-zero reference count, meaning some objects were not released."的?息.
我查????出在GetBackBuffer的?r候,但是我不知道是什?原因?解?Q方法.

1. 
   
2. void SaveBackBufferToPng(IDirect3DDevice9* pd3dDevice,WCHAR* szFilename)
   
3. {
   
4.         LPDIRECT3DSURFACE9 m_TmpSurface=NULL;
   
5.         HRESULT hr;
   
6.         D3DDISPLAYMODE display;
   
7. 
   
8.         hr=pd3dDevice->GetDisplayMode(0,&display);
   
9.         hr=pd3dDevice->CreateOffscreenPlainSurface(display.Width,display.Height,D3DFMT_A8R8G8B8,D3DPOOL_DEFAULT,&m_TmpSurface,NULL);//D3DFMT_A8R8G8B8
   
10.         hr=pd3dDevice->GetBackBuffer(0,0,D3DBACKBUFFER_TYPE_MONO,&m_TmpSurface);//<==key point
    
11.        
    
12.         D3DXSaveSurfaceToFile(szFilename,D3DXIFF_PNG,m_TmpSurface,NULL,NULL);//L"file.png"
    
13. 
    
14.         SAFE_RELEASE(m_TmpSurface);
    
15. }

Aming

hr=pd3dDevice->CreateOffscreenPlainSurface(
display.Width,
display.Height,
D3DFMT_A8R8G8B8,D3DPOOL_DEFAULT,
&m_TmpSurface,  //<------------???你多建了????]?放 ..
NULL);//D3DFMT_A8R8G8B8

接下?砟阌帜?_TmpSurface去接BackSurface
