SaveState Method

Summary

Saves the object status to a file.

Syntax

C++

public void SaveState(  
   string fileName 
)

Public Sub SaveState( _ 
   ByVal fileName As String _ 
)

public: 
void SaveState(  
   String^ fileName 
)

Parameters

fileName
The file name for which the state data will be saved.

Remarks

When saving the object state, the following will be saved:
Window Level
Object Orientation
Slab Parameters
Remove Density values
You can save the state for one object and then load it on another one.
To load the state use the LoadState method.
Saving a state normally means that engine will save the current view of the 3D volume so that when a user loads the same state at later time, it will display the object exactly the same way as when the user saved it. So, this should include rotation, scale, window/level, threshold values etc (i.e. the current properties of the object's state) and it is specific to image set used for the volume.
