GetLabelStruct

Returns the label parameters in a single structure. This structure can also be used as an argument to the IObjectManager51::CreateLabelEx() method. Each of the struct members has an equivalent ITerrainLabel5 property. For a detailed explanation of the purpose of each struct member, see the documentation for those properties. When using this structure as an argument for the CreateLabelEx() method, the client can indicate that it wants to use the system default for a specific label property. To do so, the client must set that member to a certain value. Those values appear in parenthesis in the following description.
