<br>How do we learn to use itk::NumericTraits? This does not appear in the ITK Software Guide and the doxygen is not very helpful as a use guide. There are many examples and test progams that use NumericTraits, but wading through them may not provide a concise conceptual overview of these tools (in the absence of anything better, it will have to do). A quick search on the ITK wiki does not reveal a useful guide on this topic.<br>

<br>
If I understand your question correctly, I believe you may be looking<br>
for itk::NumericTraits.<br>
<br>
You can use as follows:<br>
<br>
#include "itkNumericTraits.h"<br>
<br>
typedef unsigned char PixelType;<br>
<br>
std::cout << "max=" << itk::NumericTraits<PixelType>::max() << std::endl;<br>
std::cout << "min=" << itk::NumericTraits<PixelType>::min() << std::endl;<br>
std::cout << "zero=" << itk::NumericTraits<PixelType>::Zero << std::endl;<br>
std::cout << "one=" << itk::NumericTraits<PixelType>::One << std::endl;<br>
std::cout << "one=" << itk::NumericTraits<PixelType>::IsPositive( 42 )<br>
<< std::endl;<br>
etc...<br>
<br>
Hope this helps.<br>
<br>
Cheers, Dan<br>
