- Methods
Methods
The IXpsOMImageResource interface has these methods.
| Method | Description |

| GetStream | Gets a new, read-only copy of the stream that is associated with this resource. |
| SetContent | Sets the read-only stream to be associated with this resource. |
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
}
