IXpsOMGeometry::GetTransformLookup method (xpsobjectmodel.h)
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 |
