试了下,果然可以。
在渲染完所有东东后(Present之前)
获得BackBuffer表面
然后用D3DX的函数保存
void
ScreenShot (
char
*
filename)
{
IDirect3DSurface9
*
tmp
=
NULL;
IDirect3DSurface9
*
back
=
NULL;
//
生成固定颜色模式的离屏表面(Width和 Height为屏幕或窗口的宽高)
D3D9Device
->
CreateOffscreenPlainSurface(Width, Height, D3DFMT_A8R8G8B8, D3DPOOL_DEFAULT,
&
tmp, NULL);
//
获得BackBuffer的D3D Surface
D3D9Device
->
GetBackBuffer(
0
,
0
, D3DBACKBUFFER_TYPE_MONO,
&
back);
//
Copy一下,,需要时转换颜色格式
D3DXLoadSurfaceFromSurface(tmp, NULL, NULL, back, NULL, NULL, D3DX_FILTER_NONE,
0
);
//
保存成BMP格式
D3DXSaveSurfaceToFile(filename, D3DXIFF_BMP, tmp, NULL, NULL);
//
释放Surface,防止内存泄漏
SAFE_RELEASE(tmp);
SAFE_RELEASE(back);
}
