[Insight-users] How to define global ITK variable for different cxx files

[Xiaopeng Yang]

I tried as follows. But I am not sure it is right or not.

// globals.h 
 
#ifndef GLOBALS_H 
#define GLOBALS_H 
 
#ifndef EXTERN 
#define EXTERN extern 
#endif 


#include <itkImage.h>

#include "itkRescaleIntensityImageFilter.h"

typedef    float    InputPixelType;

typedef itk::Image< InputPixelType,  3 >   InputImageType;

typedef itk::RescaleIntensityImageFilter< 
             InputImageType, InputImageType > RescaleFilterType;

EXTERN RescaleFilterType::Pointer rescaler1 = RescaleFilterType::

#endif

Thanks.

Add a third header file defining the global.
