[Insight-users] Complementary Image: is there something in itk

[Sergiy Volkovych]

Suppose your current image pointer is CurrentImage. Then to obtain it's
complementary image you may use code like this:

ImageType::Pointer ComplementaryImage = ImageType::New();
ComplementaryImage->SetBufferedRegion(ComplementaryImage
->GetRequestedRegion());
ComplementaryImage->Allocate();

typedef itk::ImageRegionIterator<ImageType> IteratorType;
typedef itk::ImageRegionConstIterator<ImageType> ConstIteratorType;

IteratorType ComplementaryImageIt (ComplementaryImage,
ComplementaryImage->GetRequestedRegion());
ConstIteratorType CurrentImageIt (CurrentImage,
CurrentImage->GetRequestedRegion());

for (ComplementaryImageIt.GoToBegin(), CurrentImageIt.GoToBegin();
!CurrentImageIt.IsAtEnd(); ++ComplementaryImageIt, ++CurrentImageIt)
  ComplementaryImageIt.Set(1 - CurrentImageIt.Get());

Feel yourself free to use iterators - it gives you possibility to do
anything you want :)
