Gets the lookup key for the IXpsOMMatrixTransform interface that contains the resolved matrix transform for the geometry. The matrix transform is stored in a resource dictionary.

Syntax

HRESULT GetTransformLookup(
  [out, retval] LPWSTR *lookup
);

Parameters

[out, retval] lookup

The lookup key for the IXpsOMMatrixTransform interface in a resource dictionary. A NULL pointer is returned if a matrix transform lookup key has not been set or if a local matrix transform has been set.

The value that is returned in this parameter depends on which method has most recently been called to set the transform.

Most recent method called	Object that is returned in lookup
SetTransformLocal	NULL pointer.
SetTransformLookup	The lookup key set by SetTransformLookup.
Neither SetTransformLocal nor SetTransformLookup has been called yet.	NULL pointer.

Return value

The method returns an HRESULT. Possible values include, but are not limited to, those in the table that follows. For information about XPS document API return values that are not listed in this table, see XPS Document Errors.

Return code	Description
S_OK	The method succeeded.
E_POINTER	lookup is NULL.

Remarks

This method allocates the memory used by the string that is returned in lookup. If lookup is not NULL, use the CoTaskMemFree function to free the memory.
