LoadState Method

Loads the object status from a file.
public void LoadState( 
   string fileName 
Public Sub LoadState( _ 
   ByVal fileName As String _ 
void LoadState(  
   String^ fileName 


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


The load object state will affect the following features:

  1. Window Level
  2. Object Orientation
  3. Slab Parameters
  4. 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.
