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

[Lambert Zijp]

Hi Dženan,

Thank you very much!
Visual Studio 9 does not recognize decltype(), but typeid() worked fine. At
least, when you make separate if statements, like you did in your example.
When tried to use it in a switch statement, the compiler complained.

Greetings,
Lambert
