[Insight-users] image pixel value

[Luis Ibanez]

Hi Leila,


You may want use the type


             NumericTraits< T >::PrintType


For example:

   typedef BinaryImageType::PixelType             PixelType;
   typedef NumericTraits< PixelType>::PrintType   PrintType;

   PixelType pixelValue = m_VarianceImage->GetPixel( pixelIndex );

   PrintType printValue = static_cast< PrintType >( pixelValue ):
   std::cout << printValue << std::endl;


   Regards,


     Luis
