[Insight-users] Change the dimension of an index

[Gaëtan Lehmann]

Hi Alberto,

Can't you simply copy the index on the dimensions of interest from the  
3D itk::Index to the 2D itk::Index?
Something like:

   itk::Index< 2 > idx2;
   idx2[0] = idx3[0];
   idx3[1] = idx3[1];
   img->SetPixel( idx2, 90 );

Regards,

Gaëtan
