Remarks

To instantiate this interface, call CoCreateInstance as shown in the code example that follows.

IXpsOMThumbnailGenerator    *newInterface;

// Note the implicit requirement that CoInitializeEx 
//  has previously been called from this thread.

hr = CoCreateInstance(
      __uuidof(XpsOMThumbnailGenerator),
      NULL, 
      CLSCTX_INPROC_SERVER,
      __uuidof(IXpsOMThumbnailGenerator),
      reinterpret_cast<LPVOID*>(&newInterface)
      );

if (SUCCEEDED(hr))
{
    // use newInterface
    newInterface->Release();
}
else
{
    // evaluate HRESULT error returned in hr
}
 

This interface requires XpsRasterService.dll. If XpsRasterService.dll is not present when CoCreateInstance is called to create an IXpsOMThumbnailGenerator instance, CoCreateInstance returns E_FAIL.
