Writing filter with multiple outputs - do I need to provide the number of outputs already in the constructor?

Yes, that can be done. Here is how:

InsightSoftwareConsortium/ITKMontage/blob/aa09f7d0825e5baa7d7d7210466504c7527236a5/include/itkTileMontage.hxx#L101


::SetMontageSize( SizeType montageSize )
{
  if ( m_MontageSize != montageSize )
    {
    m_LinearMontageSize = 1u;
    for ( unsigned d = 0; d < ImageDimension; d++ )
      {
      m_LinearMontageSize *= montageSize[d];
      }
    this->SetNumberOfRequiredInputs( m_LinearMontageSize );
    this->SetNumberOfRequiredOutputs( m_LinearMontageSize );
    m_MontageSize = montageSize;
    m_Filenames.resize( m_LinearMontageSize );
    m_FFTCache.resize( m_LinearMontageSize );
    this->Modified();
    }
}
