Статья
06/01/2017

Provides the top-level entry into the XPS object model tree.

Although this interface does not correspond to any XPS markup, it does correspond to the XPS document, and it is required to save the components of an XPS object model tree as an XPS document.

When to implement

Never. Custom implementation of this interface is not supported.

Members

The IXpsOMPackage interface inherits from the IUnknown interface. IXpsOMPackage also has these types of members:

Methods

Methods

The IXpsOMPackage interface has these methods.

Method	Description
GetCoreProperties	Gets a pointer to the IXpsOMCoreProperties interface of the XPS package.
GetDiscardControlPartName	Gets the name of the discard control part in the XPS package.
GetDocumentSequence	Gets a pointer to the IXpsOMDocumentSequence interface that contains the document sequence of the XPS package.
GetThumbnailResource	Gets a pointer to the IXpsOMImageResource interface of the thumbnail resource that is associated with the XPS package.
SetCoreProperties	Sets the IXpsOMCoreProperties interface of the XPS package.
SetDiscardControlPartName	Sets the name of the discard control part in the XPS package.
SetDocumentSequence	Sets the IXpsOMDocumentSequence interface of the XPS package.
SetThumbnailResource	Sets the thumbnail image of the XPS document.
WriteToFile	Writes the XPS package to a specified file.
WriteToStream	Writes the XPS package to a specified stream.

Remarks

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

IXpsOMPackage    *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->CreatePackage (&newInterface);
    if (SUCCEEDED(hr))
    {
        // use newInterface

        newInterface->Release();
    }

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