[Insight-users] creating 1 voxel image not possible?

[Luis Ibanez]

Hi Maarten,

Thanks for your detailed question.

I tried your code, and...

                  It works for me


See the full code below.

I compiled it in Ubuntu Linux 9.10,
with Gcc 4.4, and the CVS version of ITK.

It compiled without errors and ran without
crashing.

It is likely that you have a configuration
problem in your build.


Have you run the program in a debugger ?


     Regards,


           Luis


--------------------------------------------------------
#include "itkImage.h"
#include "itkMatrix.h"

int main()
{
    const unsigned int Dimension = 3;
    typedef itk::Matrix<double, 4, 4> MatrixType;
    typedef itk::Image<MatrixType, Dimension> MatrixFieldType;
    MatrixFieldType::Pointer matrixfield = MatrixFieldType::New();
    MatrixFieldType::IndexType index;
    index.Fill( 0 );
    MatrixFieldType::SizeType size;
    size.Fill( 1 );
    MatrixFieldType::RegionType region( index, size );
    matrixfield->SetRegions( region );
    matrixfield->Allocate();
    MatrixType matrix;
    matrix.SetIdentity();
    matrixfield->SetPixel( index, matrix );

    return 0;
}
