[Insight-users] ImageRegionIterator inside ImageToImageFilter

[Michael Xanadu]

Thank you, it works. Do you know how to put the input of the filter directly
to the filter's output? I don't need any other filters in GenerateData(),
only the iterator. I tryed something like that, but I get an error again:

template <class TImageType, class TOutputType>
void ContourArrayFilter<TImageType, TOutputType>::GenerateData()
{
    //after iterating through input, set input directly to output:
    this->Update();
    this->GraftOutput( this->GetInput() );
}

error C2664: 'itk::ImageSource<TOutputImage>::GraftOutput' : cannot convert
parameter 1 from 'const itk::Image<TPixel,VImageDimension> *' to
'itk::DataObject *'
