Public Sub LoadState( _
   ByVal fileName As String _
)

'Usage
 
Dim instance As Medical3DObject
Dim fileName As String
 
instance.LoadState(fileName)

public void LoadState( 
   string fileName
)

 function Leadtools.Medical3D.Medical3DObject.LoadState( 
   fileName 
)

public:
void LoadState( 
   String^ fileName
)

Parameters

fileName: The file name from which the state data will be loaded.

The load object state will affect the following features:

Window Level
Object Orientation
Slab Parameters
Remove Density values

You can save this state for one object, then load it for another one.

To save the state use the SaveState method.
