[Insight-developers] Image::TransformPhysicalPointToIndex

[Lydia Ng]

Currently Image::TransformPhysicalPointToIndex
does a truncation to convert the index from
continuous space to discrete space. i.e

    for (unsigned int i =3D 0 ; i < VImageDimension ; i++)
      {=20
      index[i] =3D static_cast<long>(inputPoint[i]);
      }

Any objection if that the truncation is change
to vnl_math_rnd instead? ie.

    for (unsigned int i =3D 0 ; i < VImageDimension ; i++)
      {=20
      index[i] =3D static_cast<long>( vnl_math_rnd(inputPoint[i]) );
      }
