[Insight-users] ImageRegionIterator inside ImageToImageFilter

[Michael Xanadu]

Hi,

i wanna write my own filter dereived from ImageToImageFilter. In
GenerateData() i want to use an ImageRegionIterator, which shall get the
Input of the filter:

template <class TImageType, class TOutputType>
void ContourArrayFilter<TImageType, TOutputType>::GenerateData()
{
    typedef itk::ImageRegionIterator< TImageType > IteratorType;
    IteratorType iterator( this->GetInput(),
this->GetInput()->GetLargestPossibleRegion());
    //...
}

But this->GetInput() delivers a const Pointer while the iterator needs a
normal one. So I get:

cannot convert parameter 1 from 'const itk::Image<TPixel,VImageDimension> *'
to 'itk::Image<TPixel,VImageDimension> *'

Does anybody know how to solve the problem? I just wanna iterate the pixels
of the input.


Refards, Michael
