Hi Miri,

I am not entirely sure, where you are trying to switch to a specific datatype, 
but if you want to use it with a specific one you enter the datatype, just like 
in itk::Image< float, 3 > for a three dimensional itk Image using floats. If 
you are asking about defining the function for a specific datatype, you can 
just get rid of the parameter and define it like

template< unsigned int VImageDimension>
void AddFilter(itk::Image<float, VImageDimension>* image, mitk::Image::Pointer 
outputImage)

or even get rid of templating altogether

void AddFilter(itk::Image<float, 3>* image, mitk::Image::Pointer outputImage)


In any case, you might want to read further into the usage of templates as for 
example here http://www.cplusplus.com/doc/tutorial/templates/ .

Regards,
Caspar

Betreff: [mitk-users] Changing image type

Hi All,

I have some questions:

1. The example of template on web (awesomeFilter) gets the image type as is by 
typename

templaye<typename TPixel, unsigned int VImageDimension>
void AddFilter(itk::Image<TPixel, VImageDimension>* image, mitk::Image::Pointer 
outputImage)
{...}
 ,thus if I want to change the image type, I need to use the filter: 
itk::castingFilter. How can I get the image as any type that I want and avoid 
the casting afterwards? My intuition is telling me that it should be something 
like that:
typename<float TPixel, unsigned int VImageDimension>
but that returns errors...

2. It's really necessary to add the cpp files in the cmake file: 
moduls\MyModuleLib\files.cmake like that:

set (CPP_FILES
myCppFile1.cpp
myCppFile2.cpp)
...
I think that when I don't add that, it doesn't matter the result.


Thanks!
