SaveState Method

Saves the object status to a file.
public void SaveState( 
   string fileName 
Public Sub SaveState( _ 
   ByVal fileName As String _ 
void SaveState(  
   String^ fileName 


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

  • When saving the object state, the following will be saved:

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