Constructor Details
- VirtualStack
  
  public VirtualStack()
  
  Default constructor.
- VirtualStack
  
  public VirtualStack(int width, int height)
- VirtualStack
  
  public VirtualStack(int width, int height, ColorModel cm, String path)
  
  Creates an empty virtual stack.
  
  Parameters:
  
  width - image width
  
  height - image height
