[Insight-users] output multiple images filter

[Dennis Jen]

Hi,
  I'm writing a filter that takes in an image volume, performs some 
computation, and outputs two image volumes.  Would it be best to 
subclass from ImageToImageFilter?  Is there a superclass that outputs 
multiple images--maybe something that might be called 
ImageToImagesFilter?  I'd appreciate any help, and please let me know if 
you need more information.
  Thanks,
    Dennis
