[Insight-users] How to get & set the dimension of an itk::image dynamically?

[Luis Ibanez]

Hi Michael,

You can't use the call to GetDimension() from an image
to set the dimension of another image.

This is because GetDimension() will act at run-time, while
you need something that will make the dimension available
at compilation time.


What you need is code of the sort:

*template <class TImage>
void MyClass<TImage>::writeImage(ImageType *image)
{
    typedef itk::Image<unsigned char, TImage::ImageDimension>
OutputImageType;*
}


and in some primitive compilers
like Visual Studio 6.0 and Borland 5.5,
you may have to do:

*
template <class TImage>
void MyClass<TImage>::writeImage(ImageType *image)
{*
*typedef itk::Image<unsigned char, *
:itk::GetImageDimension< TImage >::ImageDimension
*> OutputImageType;*
}


    Regards,


           Luis
