[ITK-users] Composite Filter with variable stdvector of filters inside

[Matt McCormick]

Hi Ignacio,

If I understand corrections, this may do want is desired:

void SetNumberOfZSlices( int slices )
{
if( m_NumberOfZSlices != slices )
  {
  this->m_NumberOfZSlices = slices;
  this->UpdateNumberOfFilters();
  this->Modified();
  }
}

and a similar implementation for SetNumberOfTimeFrames().

Hope this helps,
Matt
