Remarks

The code example that follows illustrates how to create an instance of this interface.

IXpsOMImageResource    *newInterface;
// The following values are defined outside of 
// this example.
//  IStream            *acquiredStream;
//  XPS_IMAGE_TYPE     contentType;
//  IOpcPartUri        *partUri;
    
// Note the implicit requirement that CoInitializeEx 
//  has previously been called from this thread.

hr = CoCreateInstance(
    __uuidof(XpsOMObjectFactory),
    NULL,
    CLSCTX_INPROC_SERVER,
    _uuidof(IXpsOMObjectFactory),
    reinterpret_cast<LPVOID*>(&xpsFactory)
    );

if (SUCCEEDED(hr))
{
    // The partUriString and acquiredStream variables 
    //   are defined outside of this example.
    hr = xpsFactory->CreatePartUri(partUriString, &partUri);
    if (SUCCEEDED(hr))
    {
        hr = xpsFactory->CreateImageResource (
            acquiredStream,
            contentType,
            partUri,
            &newInterface);
        if (SUCCEEDED(hr))
        {
            // use newInterface

            newInterface->Release();
        }
        partUri->Release();
    }
    xpsFactory->Release();
}
else
{
    // evaluate HRESULT error returned in hr
}
