[ITK] [ITK-users] How to determine PixelType of itk::Image

[Dženan Zukić]

Hi Lambert,

the classic way is using a bunch of if-else's.

if (decltype(ValueType)==decltype(int))
{
//int specific processing
}
else if (decltype(ValueType)==decltype(itk::RGB<char>))
{
//RGB<char> specific processing
}
​else if ...​

​If you can't use C++11's decltype then use typeid from <typeinfo>​ header.

Regards,
Dženan
