[Insight-users] MaskImageFilter wiki example

[Chr. Rossmanith]

Hi,

does the conditional compilation (part of the code see below) really 
work? I have to put  #include "itkImage.h" before #if, otherwise I get 
the #if branch instead of the #else branch even if I use ITKv4. For 
testing purposes I had some output which showed ITK_VERSION_MAJOR with 
value 4 but despite that the expression ITK_VERSION_MAJOR<4 was 
evaluated as true.

#if  ITK_VERSION_MAJOR<4   //These are all defaults in ITKv4
//  Not supported in ITKv3.
int main(int argc, char *argv[])
{
   return 0;
}
#else
#include "itkImage.h"
#include "itkImageFileReader.h"
#include "itkMaskImageFilter.h"

#include "QuickView.h"
