GetDictionary	Gets a pointer to the resolved IXpsOMDictionary interface of the dictionary associated with the canvas.
GetDictionaryLocal	Gets a pointer to the IXpsOMDictionary interface of the local, unshared dictionary.
GetDictionaryResource	Gets a pointer to the IXpsOMRemoteDictionaryResource interface of the remote dictionary resource.
GetUseAliasedEdgeMode	Gets a Boolean value that determines whether the edges of the objects in the canvas are to be rendered using the aliased edge mode.

Remarks

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

IXpsOMCanvas    *newInterface;

// 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))
{
    hr = xpsFactory->CreateCanvas (&newInterface);
    if (SUCCEEDED(hr))
    {
        // use newInterface

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