Summary

Loads the object status from a file.

Syntax

C++

public void LoadState(  
   string fileName 
)

Public Sub LoadState( _ 
   ByVal fileName As String _ 
)

public: 
void LoadState(  
   String^ fileName 
)

Parameters

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

Remarks

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.
